文摘

The front cover image, provided by Kai Zhang and co-workers, illustrates a precise bandgap engineering strategy to achieve fine justification of the valence and conduction band positions of nanoporous poly-benzobisthiadiazoles to optimally bracket the redox potential of the targeted photoredox reaction via copolymerization of the electron-withdrawing moieties into the polymer backbone. The enhanced photocatalytic activity of the polymers was demonstrated in the synthesis of 1,2,3,4-tetrahydroquinoline, an important motif in pharmaceutical compounds, via photooxidative cyclization of N,N-dimethylanilines with maleimides. Details can be found in the communication on pages 2576–2582 (Z. J. Wang, S. Ghasimi, K. Landfester, K. A. I. Zhang, Adv. Synth. Catal. 2016, 358, 2576–2582; DOI: 10.1002/adsc.201600125).
