an initial effort to discern some of the fine features of cholinergic anionic receptors, a study was made on inhibitors of acetylcholinesterase which used inhibitors that are relatively free from conformational variation. The inhibitors used were quaternized 1-azabicyclo (2.2.2)octanes. The bicyclic parent amine was prepared by several conventional procedures. The salts were evaluated as competitive

present article, we show how organic templates can efficiently transform a complex dynamic imine library into a dynamic iminemacrocycle. Not only is the constitution well controlled, but also the syn/anti host configuration is efficiently selected and even the orientation of the guest in the asymmetric cavity of the host can be well aligned. This is attributed to the delicate balance and the cooperation

A highly efficient artificial light-harvesting system (ALHS) in the aqueous phase with a two-step sequential energy transfer process has been successfully constructed based on the host–guest interaction between a water-soluble pillar[5]arene (WP5) and a bola-type bis(4-phenyl)acrylonitrile derivative (BPT), as well as two different hydrophobic fluorescent dyes (4,7-bis(thien-2-yl)-2,1,3-benzothiadiazole

A dual-responsive supra-amphiphile was constructed based on a water-soluble pillar[7]arene and a pyrene-containing guest. The self-assembly morphology of this supra-amphiphile could be adjusted by changing pH or irradiation by UV light.
