RS Latch Realization by Using Asymmetric Porphyrin Covalently Connecting to Mesoporous Silica Films
卟啉 分子逻辑 介孔分子筛薄膜 共价接 RS触发器 porphyrin molecular logic mesoporous silica thin film covalently connected RS-latch
摘要
合成了5-(4-氨基苯基)-10,15,20-三苯基卟啉(ATPP), 并成功将其以共价嫁接的形式固载于介孔二氧化硅薄膜。基于卟啉化合物对酸碱的特异性响应, 实现了对RS触发器逻辑功能的模拟。卟啉化合物被共价固载于介孔薄膜材料使得该分子逻辑器件具有相对较大的表面积、周期性排布的均一孔道结构以及高的光透过性等介孔薄膜材料的优异性质。这种混合多孔结构不但有利于嫁接于介孔材料中的卟啉与酸碱的更有效相互作用, 而且还使酸碱输入能够被更加彻底地清除。
Abstract
5-(4-aminophenyl)-10,15,20-triphenyl-porphyrin (H2ATPP) was prepared and covalently connected to mesoporous silica thin films. Based on the porphyrin compoundss characteristic of being sensitive to acid and base, the molecular logics of RS-latch for sequential logic were achieved. The molecular logics have the advantages of larger surface area, periodic arranged uniform pore structure, and high transmission because of the covalent connection of porphyrin compounds to mesoporous silica. This hybrid mesoporous structure is not only advantageous to the interaction between the inputs and response materials, but also advantageous to the separation of the response materials and inputs without information loss.
