Redox-modulated near-infrared electrochromism, electroluminochromism, and aggregation-induced fluorescence change in an indolo[3,2-b]carbazole-bridged diamine system
A new indolo[3,2-b]carbazole-based compound (1) has been developed by linking two redox-active diphenylamine moieties to the rigid pi-conjugated indolo[3,2-b]carbazole core. Its first two completely reversible oxidation steps are mainly related to the two terminal amine centers, and a moderate electron coupling between these amine centers has been determined. The associated oxidized species 1+and 12+both exhibited strong NIR absorptions, and a completely reversible conversion among three different colors (light-yellow, red, and blue, corresponding to neutral, monocationic and dicationic states, respectively) could be realized. In addition, reversible switching between turn-off and turn-on of its fluorescence could be accomplished by electrochemical oxidation and reduction, respectively. Compound 1 also exhibited obvious fluorescence color changes during its aggregate-forming process, and its solid showed bright-yellow fluorescence with a high emission quantum yield of 30%.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: Pd2(DBA)3, you can also check out more blogs about52409-22-0
