摘要

将具有氨基功能团的不对称中位四苯基卟啉以共价嫁接的形式固载于介孔二氧化硅薄膜.当将含有卟啉化合物的介孔薄膜材料置于酸性或碱性溶液中并取出时

卟啉在酸性或碱性环境中的状态会被完整的保存下来

进而实现对具有逻辑记忆功能的反馈回路(Feedback loop)的模拟.这种分子逻辑器件兼具了介孔薄膜材料的优异性质:相对较大的表面积不但有利于输入介质与响应单元更有效地接触

还有益于输入介质的彻底清除

避免其残留下来影响下次逻辑输入;周期性排布的均一孔道结构更加有利于器件的后期加工;高的透过性使得输出(Output)更容易被光学仪器所检测.

Abstract

An asymmetric porphyrin derivative of 5-(4-aminophenyl)-10

20-triphenyl-porphyrin (H

ATPP) has been successfully covalently connected to photo-permeable mesoporous silica thin films as a unit to mimic logic function. This hybrid mesoporous structure is not only advantageous to the interaction between inputs and response materials

but also to separation of the response materials and inputs without information lost. Then molecular logics with the function of memory

based on its characteristic of being sensitive to acid and base

are achieved. With different initial states

it could be handily described as feedback loop for sequential logic.
