Abstract: Switchable inversion of chirality between opposite handedness by varying pH is discovered for a histidine pendant polymer, polymethyl (4-vinylbenzoyl) histidinate (PBHis), as demonstrated by the circular dichroism as well as the changes of hydrodynamic radius… read more here.

Abstract: A surprising inversion of chirality of the -ITV zeolite framework is observed when the ethyl group of the enantiopure N,N-ethyl-methyl-pseudoephedrinium organic structure-directing agent is replaced by a benzyl or 2-methylbenzyl group, keeping the same molecular… read more here.
