A carbon nitride material can be combined with homogeneous nickel catalysts for light-mediated cross-couplings of aryl bromides with alcohols under mild conditions. The metal-free heterogeneous semiconductor is fully recyclable and couples a broad range of electron-poor aryl bromides with primary and secondary alcohols as well as water. The application for intramolecular reactions and the synthesis of active pharmaceutical ingredients was demonstrated. The catalytic protocol is applicable for the coupling of aryl iodides with thiols as well.

Paragraph 0037; 0039, (2018/09/12)
The invention relates to a derivative based on a 1,3,5-triazine structure and a fluorene unit and application thereof. The 1,3,5-triazine derivative and the fluorenyl derivative are fixed into a single molecule through sp3 hybrid carbon atoms by means of a Pd(dba)2 catalytic C-H coupled reaction, and a bipolar body material is prepared. The synthesis method is simple, raw materials are easy to obtain, and industrial development is facilitated. The bipolar body material has the balanced carrier transport capability, the high triplet energy level, the wide energy gap and the high quantum efficiency. According to the bipolar body material, under the film state, due to the interplanar pi-pi effect of the 1,3,5-triazine, excimer fluorescence spectrum red shifting is formed. The body material has the good solubility in a common organic solvent and can be applied to preparing a solution machined electroluminescent device. The body material is applied to the electroluminescent device, the device efficiency is improved, driving voltage and efficiency roll-off are lowered, and the service life of the device is prolonged.

The ligands of certain G-protein-coupled receptors (GPCRs) have been identified as endogenous lipids, such as lysophosphatidylserine (LysoPS). Here, we analyzed the molecular basis of the structure-activity relationship of ligands of GPR34, one of the LysoPS receptor subtypes, focusing on recognition of the long-chain fatty acid moiety by the hydrophobic pocket. By introducing benzene ring(s) into the fatty acid moiety of 2-deoxy-LysoPS, we explored the binding site's preference for the hydrophobic shape. A tribenzene-containing fatty acid surrogate with modifications of the terminal aromatic moiety showed potent agonistic activity toward GPR34. Computational docking of these derivatives with a homology modeling/molecular dynamics-based virtual binding site of GPR34 indicated that a kink in the benzene-based lipid surrogates matches the L-shaped hydrophobic pocket of GPR34. A tetrabenzene-based lipid analogue bearing a bulky tert-butyl group at the 4-position of the terminal benzene ring exhibited potent GPR34 agonistic activity, validating the present hydrophobic binding pocket model.
