Herein we designed and synthesized three photoinduced electron transfer ( pet ) phosphoroionophores , ( 1 - bromo - naphthalen - 2 - ylmethyl ) - bis - ( 2 - hydroxyl - ethyl ) - amine ( bnd ) , ( 1 - bromo - naphthalen - 2 - yl - methyl ) - bis - ( 2 - cholor - ethyl ) - amine ( bnc ) and 7 , 16 - bis - ( 1 - bromo - naphthalen - 2 - ylmethyl ) - 1 , 4 , 10 , l3 - tetraoxa - 7 , l6 - diaza - cyclooctadecane and their phosphorescent characteristics were studied , compared with 1 - bromo - 2 - methylnaphthalene . the experimental results showed that strong p hosphorescence could be observed in p - cyclodextrin aqueous solution only at low ph value . this system combined and and not function to produce a three - input inhibit ( inh ) logic gate 实验结果表明，在环糊精水溶液中只有在较低ph时，才能有效抑制分子内的pet过程，使磷光体发射强的磷光，体系的磷光状态为off - on ，同时体系包含了and ( - cdandproton )和not ( o _ 2 )逻辑功能，可作为一种三输入的inhibit逻辑开关。
