Currently, tens-of-thousands of chemicals are used in Japan, and their presence in and impact on aquatic ecosystems are poorly understood. Because conventional risk evaluation processes using target analysis and biological tests are time-consuming and costly, it is challenging to investigate all substances. Therefore, we aimed to develop a rapid and highly efficient screening scheme for identifying hazardous organic micropollutants (OMPs) in aquatic ecosystems. The scheme is divided into two steps: chemical analysis and risk evaluation. First, a comprehensive screening method (CSM) using gas chromatography (GC)-mass spectrometry (MS) and a database containing nearly 1000 compounds is used to identify known compounds, and nontargeted analysis is carried out using a GC x GC-time-of-flight (TOF)MS to detect compounds not registered in the database. Secondly, the predicted toxicity values obtained by quantitative structure-activity relationship (QSAR) are used to evaluate and rank the ecological risk of each detected OMPs and to identify priority compounds for detailed survey. To assess the proposed scheme, we surveyed representative urban rivers in Japan and ranked the potential toxicity of the identified compounds. The total number of compounds detected in water from each river ranged from 29 to 87, and the total concentrations ranged from 2.3 to 63 mu g L-1. Pharmaceuticals and personal care products, such as crotamiton and galaxolide, were identified in the urban rivers and found to have high ecotoxicity rankings. Thus, the scheme combining CSM and risk evaluation using QSAR is a novel screening that can identify candidates with high ecological risk in aquatic environment rapidly and efficiently.

The radiationless transition rate based on intra-molecular vibrations from the lowest excited triplet state (T-1) at room temperature [k(nr)(RT)] is crucial for triplet energy harvesting in optoelectronics and photonics applications. Although a decrease of k(nr)(RT) of chromophores with strong intermolecular interactions is often proposed, scientific evidence for this has not been reported. Here we report a method to predict k(nr)(RT). We optically estimated k(nr)(RT) of various molecularly dispersed chromophores with a variety of transition characteristics from T-1 to the ground state (S-0) under appropriate inert liquid or solid host conditions. Spin-orbit coupling (SOC) without considering molecular vibrations was not correlated with the estimated k(nr)(RT). However, the estimated k(nr)(RT) was strongly correlated with a multiplication of SOC considering vibrations freely allowed at room temperature and the Franck-Condon factor. This correlation revealed that k(nr)(RT) of many heavy-atom-free chromophores with a visible T-1 -S-0 transition energy and local excited T-1-S-0 transition characteristics is intrinsically less than 10(0) s(-1) even when vibrations freely occur. This information will assist researchers to appropriately design materials without limitations regarding intermolecular interactions to control T-1 lifetime at room temperature and facilitate triplet energy harvesting.

A di(o-tolyl)borylgold complex was synthesized via the metathesis reaction of a gold alkoxide with tetra(o-tolyl)diborane(4). The resulting diarylborylgold complex exhibited a Lewis acidic boron center and a characteristic visible absorption that arises from its HOMO-LUMO excitation, which is narrower than that of a previously reported dioxyborylgold complex. The diarylborylgold complex reacted with isocyanide in a stepwise fashion to afford single- and double-insertion products and a C-C coupled product. Reactions of this diarylborylgold complex with C = O/N double bond species furnished addition products under concomitant formation of Au-C and B-O/N bonds, which suggests nucleophilic reactivity of the gold metal center. DFT calculations provided details of the underlying reaction mechanism, which involves an initial coordination of the C = O/N bond to the boron vacant p-orbital of the diarylboryl ligand followed by a migration of the gold atom from the tetracoordinate sp(3)-hybridized boron center, which is analogous to the reactivity of the conventional sp(3)-hybridized borate species. The DFT calculations also suggested a stepwise mechanism for the reaction of this diarylborylgold complex with isocyanide, which afforded three different reaction products depending on the applied reaction conditions.

12-Deoxyphorbol-13-phenylacetate (DPP), found in Euphorbia resinifera, is a prototype of a new class of phorbol derivatives that function as protein kinase C activators with potent anti-tumor-promoting activity. To better understand the biosynthesis of DPP in E. resinifera and develop methods for its production, we used next-generation sequencing technologies to build a transcriptome dataset. We obtained a total of approximately 27,102,078 clean reads that were assembled into 90,448 unigenes. Of those, 129 and 59 unigenes were identified in the Terpenoid Backbone Biosynthesis (TBB) (KEGG map00900) and the Diterpenoid Biosynthesis (DB) (KEGG map00904) pathways, respectively. We investigated the expression patterns of 23 DPP biosynthesis-related genes and validated the results by quantitative real time PCR. The results showed that CMK (4-diphosphocytidyl-2-C-methyl-o-erythritol kinase), MECS (2-C-methyl-D-erythritol 2,4-cyclodiphosphate synthase), HDS (1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate synthase), and IPI (Isopentenyl-diphosphate Delta-isomerase) of the methylerythritol 4-phosphate (MEP) pathway had a higher expression compared to other genes of TBB, whereas the expression levels of genes involved in the mevalonic acid (MVA) pathway were relatively lower and not significantly different from each other. Furthermore, the expression of the 23 genes in root, stem and young stem differed, and the statistical results indicated that HMGS (Hydroxymethylglutaryl-CoA synthase), MVK (mevalonic acid), MECT (2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase), MECS, HDS and IPI in the TBB pathway as well as KS in the DB pathway were significantly and positively correlated with the CS (casbene synthase) gene. These results suggested that both cytosol-localized MVA and plastid-localized MEP pathways may have a significant contribution in DPP accumulation, with MEP pathway playing a dominant role. To the best of our knowledge, this study is the first transcriptome analysis of E. resinifera and the results reported here will aid the identification of functional genes and better understanding of DPP biosynthesis.

Several ethylenedioxy-bridged bisarenes with a variety of type and number of aryl groups were synthesized to study non-covalent dispersion-driven inter- and intramolecular aryl-aryl interactions in the solid state and gas phase. Intramolecular interactions are preferably found in the gas phase. DFT calculations with and without dispersion correction show larger interacting aromatic groups increase the stabilization energy of folded conformers and decrease the intermolecular centroid-centroid distance. Single-molecule structures generally adopt folded conformations with short intramolecular aryl-aryl contacts. Gas electron diffraction experiments were performed exemplarily for 1-(pentafluorophenoxy)-2-(phenoxy)ethane. A new procedure for structure refinement was developed to deal with the conformational complexity of such molecules. The results are an experimental confirmation of the existence of folded conformations of this molecule with short intramolecular aryl-aryl distances in the gas phase. Solid-state structures are dominated by stretched structures without intramolecular aryl-aryl interactions but interactions with neighboring molecules.

Strategies for developing purely organic materials exhibiting both high efficiency and persistent room-temperature phosphorescence (RTP) have remained ambiguous and challenging. Herein, we propose that introducing an intermediate charge transfer (CT) state into the donor-acceptor binary molecular system holds promise for accomplishing this goal. Guest materials showing gradient ionization potentials were selected to fine-tune the intermolecularly formed CT state when doped into the same host material with a large electron affiliation potential. Such a CT intermediate state accelerates the population of the triplet exciton to benefit phosphorescent emission and decreases the phosphorescence lifetime via quenching the long-lived triplet excitons. As a result, a trade-off between a long phosphorescence lifetime (595 ms) and a high phosphorescent quantum yield (27.5%) can be obtained by tuning the host-guest energy gap offset. This finding highlights the key role of CT in RTP emission and provides new guidance for developing novel RTP systems.

Herein, we report an intramolecular radical cyclization reaction towards the synthesis of pyrrolidinone derivatives via metal-free photoredox catalysis under irradiation from blue LEDs. Some of the remarkable features of this protocol include synthetic efficiency, green reaction profile, easy isolation of products and short reaction time. The photophysical properties of synthesized compounds were investigated via steady state and time-resolved fluorescence spectroscopy in the solid state. Results showed the promising opportunity for their spectral tuning together with large Stokes-shifted and highly active fluorescence emission, thus indicating that these molecular scaffolds can be effective probes for the biological applications and development of opto-electronic devices.
