Carbazole analogues have been known to show interesting fluorescent properties. A chromatography free synthesis of 1,8-dipyridyl-3,6-di-(tert-butyl)-9H carbazole (1) has been developed. The effect of binding different metals in order to fine-tune the photophysical and catalytic properties of 1, a potential L2X NNN pincer ligand, is an ongoing project in our lab. Initial studies of 1 performed in our group have demonstrated 1 to be a turn-on fluorescence sensor for zinc ions in both protic and aprotic solvents. This research will discuss the synthesis of a series of novel N-substituted 1,8-dipyridyl carbazoles and the effect different N-substituents have on the metal binding and optoelectronic properties of ligand system 1.
