Design And Synthesis Of Naphthidine And A Perfluorinated Dithienylethene Chemical Sensor

In recent years,the research on photochromic functional materials has been becoming increasingly popular owing to their potential applications as sensors,photoresponsive self-assemblies,optical memory storage,live cell imaging,molecular logic gates,and multifunctional switches.Among diverse photochromic compounds,diarylethene derivatives are the most promising candidate photochromic system because of their fast response,excellent thermal stability and outstanding fatigue resistance.Due to the distinct feature,an increasing number of diarylethenes with various functional groups have been extensively developed.And in recent decades,based on binaphthol derivatives has become an important class of chemical sensors in small molecules and ions recognition applications,for it is an excellent chiral ligands and auxiliary agents,as well as unique hand and rigid structure,also play an extremely important role in the induction of chiral.Binaphthol and coupon Naphthidine structure similar,just replace the phenolic hydroxyl group binaphthol with amino,and nucleophilic than hydroxyl amino.So united Naphthidine in addition to outside the structure characteristics of the binaphthol,and are more likely to become a chiral ligands.In numerous photochromic compounds,the use of diaryl ethylene and Naphthidine stitching together in the form of schiff base,in addition to play diaryl ethane in isomerization of light absorption spectrum of the process of change and with the change of other physical and chemical properties,the nature of the reversible change control by light not only,also can apply Naphthidine to molecular switch,photochemical sensors,and other areas of the molecules,making of which Naphthidine derivatives has important application value in the fluorescent sensors.Based on the above theory,we design a perfluorinated dithienylethene,respectively with biphenyl thiophene,methyl thiophene,isoxazole and thiophene aldehyde changed vinyl aromatic side ends,which formed 4 different perfluorinated diarylethene derivativeand Naphthidine to get the target of our product,finally,we got the 4 Naphthidine and perfluorinated dithienylethene fluorescent chemical sensors by 24-step synthesis.
