The construction of layered covalent carbon nitride polymers based on tri-s-triazine units has been achieved by using nucleobases (adenine, guanine, cytosine, thymine and uracil) and urea to establish a two-dimensional semiconducting structure that allows band-gap engineering applications. This biomolecule-derived binary carbon nitride polymer enables the generation of energized charge carrier with light-irradiation to induce photoredox reactions for stable hydrogen production and heterogeneous organosynthesis of C−O, C−C, C−N and N−N bonds, which may enrich discussion on chemical reactions in prebiotic conditions by taking account of the photoredox function of conjugated carbonitride semiconductors that have long been considered to be stable HCN-derived organic macromolecules in space.

从生物分子合成层状碳氮化物进行光氧化还原转化

通过使用核碱基（腺嘌呤，鸟嘌呤，胞嘧啶，胸腺嘧啶和尿嘧啶）和尿素建立二维半导体结构，实现带隙工程应用，从而实现了基于三-s-三嗪单元的层状共价氮化碳聚合物的构建。。这种生物分子衍生的二元氮化碳聚合物可通过光辐照生成带电电荷载流子，从而引发光氧化还原反应，从而稳定地产生氢并生成C-O，CC-，C-N和N-N键的异质有机合成。考虑到共轭碳氮化物半导体的光氧化还原功能，长期以来人们一直认为它们是太空中稳定的HCN衍生有机大分子，从而丰富了有关益生元条件下化学反应的讨论。
