It was found that the bridging reaction is selectively, at least, preferably at 1,3\|position for p \|tert\|butylcalix\arene and p \|tert\|b utylcalix\arene, 1,5\|position for p \|tert \|butylcalix\arene. Taking the yield of bridged calixarene as a comparsion standard, the activity decreases with the increasing of the number of phenolic units in calixarene.展开更多

The structure and morphology of vesicles were different when the copper （Ⅱ） salt was added to the solution. The results showed that both the counterions and the ligands had strong influence on the configuration of coordinated structures and packing model in bilayer membrane of vesicles.展开更多
