New Chemical Family of [n-CxH(2x+1)NEt3][BEt3Me] Showing Ionic Plastic-Crystal (x = 4, 5), Rotator-Crystal (x = 6, 7) and Liquid-Crystal Phases (x = 8–16)
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
