Carbazole capped Schiff base and its boron difluoride complex as luminescent columnar phases with application as turn on chemosensor towards Al3+ as well as WLED
Three carbazole Schiff base derived hexacatenar liquid crystals (LCs) L/n (n= 12, 14, 16) composed of salicylaldimines as the central core with N-trialkoxylbenzyl carbazole capped at one side and trialkoxybenzoate capped at the other side have been synthesized. The BF2 complex of L/12 was also successfully prepared. Both carbazole Schiff bases L/n and BF2 complex L-BF2/12 can self-assemble into luminescent Colsqu/p4mm LC phases with local helical structures in their bulk states. L/n can additionally self-assemble into luminescent organogels with winkled morphologies. Study on the photophysical property indicates that both L/12 and its BF2 complex L-BF2/12 show large Stokes shift with yellow greenish emission. L/12 shows AIEE effect and can be applied as turn on Al3+ chemical sensors. BF2 complex L-BF2/12 with stronger emission than L/12 has been used to generate a white light emission diode (WLED).
期刊介绍：
Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied.
Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media.
The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
