I found the field of Chemistry; Science & Technology – Other Topics very interesting. Saw the article Intramolecular Charge Transfer and Extended Conjugate Effects in Donor–Acceptor-Type Mesoporous Carbon Nitride for Photocatalytic Hydrogen Evolution published in 2019.0. COA of Formula: C7H8N2O, Reprint Addresses Huang, LM (corresponding author), Southern Univ Sci & Technol, Dept Chem, Shenzhen 518055, Guangdong, Peoples R China.. The CAS is 64-10-8. Through research, I have a further understanding and discovery of 1-Phenylurea
Inspired by donor-acceptor (D-A) polymers in organic solar cell and the extended conjugation effect, a conceptual design of D–A-type mesoporous carbon nitride with benzene or thiophene as a -spacer is proposed as an efficient photocatalyst for hydrogen evolution. The photocatalyst was successfully synthesized by a one-pot thermopolymerization based on nucleophilic substitution and a Schiff-base chemical reaction. On the molecular level, the insertion of an in-plane benzene as a -spacer by forming covalent bonds C=N (acceptor) and C-N (donor) interrupts the continuity of tri-s-triazine units and maintains the intrinsic – conjugated electronic system. Synchronously, the enlarged electron delocalization and the intramolecular charge transfer induced by polarization provide force-directed migration of electrons, leading to boosted optical absorption capability and enhanced photogenerated carrier separation. With the synergistic effects of the mesoporous structure and excellent optical and electronic properties, a fivefold increase in the H-2 evolution rate compared with that of pristine g-C3N4 was achieved with robust performance. In addition, other simple aromatic heterocyclic compounds (e.g., pyridine, thiophene and furan)-based D–A structures with a higher hydrogen evolution rate (up to sevenfold increase) were also explored to broaden the application for the design of novel photocatalysts.
