In the aza-Henry reaction, the electron donor is not a sacrificial reagent but acts as the substrate, hence the scheme in Fig. 1a does not fully apply. Nonetheless, the initial photoinduced electron transfer from THIQ to excited [Ru(bpz)3]2+ and [Cr(dqp)2]3+ is quantitative given the...
The last section of the paper, "Conclusions," outlines the entire work. Research approach The Web of Science, Scopus, PubMed, and Google Scholar were among the databases searched as criteria for including and excluding the study. The search was conducted using key terms related to the ...
Covalent organic frameworks, cross-linked crystalline polymers constructed from rigid organic precursors connected by covalent interactions, have emerged as a promising class of nanoporous materials owing to their highly desirable combination of attribut
