Abstract
A series of butterfly-like molecules that undergo controlled photoinduced structural change (PSC) and exhibit tunable dual emission are reported by B. Ma, C. Huang, and co-workers in their Communication on page 9591 ff. The precise control of the PSC processes and the dual emission is achieved by molecular engineering of the potential energy surface of the excited state.

Cross-Coupling In their Communication on page 9502 ff., M. G. Organ et al. describe the cross-coupling of five-membered-ring heterocycles with secondary alkyl zinc reagents in the presence of the new precatalysts Pd-PEPPSI-IPentCl and Pd-PEPPSI-IHeptCl.1 Photocatalysis The selective room-temperature conversion of formic acid into either hydrogen or carbon monoxide is described by E. Reisner et al. in their Communication on page 9627 ff. The reaction is catalyzed by inexpensive CdS nanocrystals under irradiation with visible light.1 Lithium-Ion Batteries In their Communication on page 9663 ff., K. Kang et al. report a rechargeable Li–SO2 battery with an energy efficiency that is significantly better than that of the Li–O2 system.1
