Design And Synthesis Of Arylmaleimide And Its Application In The Molecuar Logic Gates

Traditional logic gates are based on silicon materials,their inputs and outputs signals are conducted in the form of current operations,their operational rules are binary operators.With the failure of Moore's law and the limitation of the physical space,traditional logic gates got bottleneck,so we need new logic gates.Since De Silva proposed the first molecular level AND logic gate in 1993,the field of molecular logic gates is favored by more and more researchers.Compared to traditional logic gates,molecular logic gates have series of advantages,such as operations in the nanoscale,none wires,molecular regulation,faster calculation,etc.Arylmaleimide are good fluorescence,they have kinds of advantages,such as good stability,high fluorescence,easy modifition,easy synthesis.So they can be applied in ions detection,solid-state fluorescence information storage,OLED,etc.This article is based on Arylmaleimide for fluorophore,we synthesized a series of chemical sensing materials,which are applied in molecular logic gates.The specific contents are as follows:1.Two chemical sensing molecules were synthesized by bisindolymaleimide as fluorophore and phenylaza-crown ether and benzo-15-crown-5 respectively as receptors,which structure verified by mass spectrometry and NMR.In ion detections,there are different fluorescence responses on detections of different metal ions,based on this property,we can design the molecular keypad lock,4:2 encoder,INH logic gate and the demultiplexer.2.In order to improve the fluorescence intensity,two chemical sensing molecules were synthesized by bisphenylmaleimide and bisphenylmaleimide respectively as fluorophores and N,N-dimethyl amine as receptor,which structure verified by mass spectrometry and NMR.In ion detections,there are different spectrals responses on detections of different metal ions,which be changed over time,based on these properties,we can design sequential half-adder and complex molecular keypad lock.3.In order to improve the coordination ability,two chemical sensing molecules were synthesized by bisphenylmaleimide and bisindolymaleimide respectively as fluorophores and DPA as receptor,which structure verified by mass spectrometry and NMR.In ion detections,there are different fluorescence responses on detections of different metal ions,based on this property,we can design INH logic gate and molecular keypad lock.
