Synthesis and Optical Properties of Novel Carbazole Derivatives Containing Pyridine Ring

A series of novel monodisperse, well‐defined molecules with a pyridine core and carbazole arms were synthesized by simple procedures with Iodo‐reaction and Ullmann reaction. Their structures were confirmed by IR, 1 H NMR, 13 C NMR, and elementary analysis. Moreover, the fluorescence spectra showed that these compounds exhibited strong fluorescence with the maximum wavelengths ranging from 373 to 385 nm.
