In the title compound, C16H17NO4S, the heterocyclic ring is almost planar (r.m.s. deviation = 0.007Å) and the dihedral angle between the benzene rings is 28.18 (10)°. The N-C-C-C torsion angle for the central chain is 62.4 (3)°: overall, the mol-ecule has a Z-shape. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R 2 (2)(8) loops.

The operation mechanisms and energy losses for organic solar cells are essentially determined by the exciton binding energies () of organic active materials. Because the factor of chemical modifications is precluded, polymorphisms featuring different packing motifs of the same molecular structures provide an ideal platform for revealing the influence of solid-state packing. Herein, we have calculated the values in three different cystal phases of a representative acceptor-donor-acceptor molecular acceptor (IDIC) by the self-consistent quantum mechanics/embedded charge approach.

A series of Ti/Li/Al ternary layered double hydroxides (TiLiAl-LDHs) with different Ti:Li:Al molar ratios were prepared by a coprecipitation method for photocatalytic CO reduction. It was demonstrated that the contents of anions between the layers of Ti/Li/Al-LDHs greatly determined the photocatalytic activity for CO reduction. With Ti:Li:Al molar ratios optimized to be 1:3:2, the largest contents of [Formula: see text] anion and hydroxyl group were obtained for the TiLiAl-LDHs sample, which exhibited the highest photocatalytic activity for CO reduction, with CH production rate achieving 1.
