Desigh And Assembiy Some Functional Luminol Derivatives

Luminol derivatives applied in biological system and functional material fields areone of the most important organic compounds designing bisfunctional amphiphiles andorganized assembly system. Based on the previous work, some special amphiphiles,including luminol derivatives with aromatic substituted groups, bolaamphiphile withhydrophobic, other special structure of the luminol derivatives and gelation experiments,have been designed and synthesized. and their organized supramolecular assemblies at theair/water interface have also been investigated, which may broaden the traditional researchareas about LB film, can give some perspectives and clues for the relative research in thefuture.First, Some functional luminol derivatives with aromatic substituted groups havebeen designed and synthesized from the reaction of the corresponding aromatic acylchloride precursors with luminol. It has been found that depending on the size of aromaticgroups, the formed luminol derivatives showed different properties, indicating distinctregulation of molecular skeletons. UV and IR data confirmed commonly the formation ofimide group as well as aromatic segment in molecular structures. Thermal analysisshowed that the thermal stability of luminol derivatives with p-phthaloyl segment was thehighest in those derivatives. The difference of thermal stability is mainly attributed to theformation of imide group and aromatic substituent groups in molecular structure.Second, some series of bolaform amphiphiles with distinct structures have been alsodesigned, and their interfacial assembling behaviors were investigated. In the course of theexperiment, These research results showed clearly that the spacer configuration changesprocess in the LB film. Through the careful measurements, such as UV, IR and AFM, wehave systematically characterized the interfacial behaviors and obtained some usefulconclusions.Moreover, we have done some groping research work about the interfacial behaviorsof luminol amphiphiles with special structure. Long-Chain plays an important role inmolecular structure. The present results have demonstrated that the special properties ofluminol derivatives can be turned by modifying molecular structures of objective compounds with proper substituted groups, which show potential application in functionalmaterial field and ECL sensor. At the same time, The Tri-C16-Lu showed excellent gellingcapability in various solvents. SEM observation proves that the gels having differentappearances possessed very different microstructures and superstructures.
