Abstract A variety of novel 2, 5-diaryl-indolizines have been prepared through the palladium- catalyzed cross-coupling reactions of organozinc reagents prepared from 2-aryl-indolizines with aromatic halides. The photophysical properties of representative compounds indicate that the 2, 5-diaryl-indolizines are promising candidates to be used in optoelectronic devices and biomolecular labeling. In addition, cyclic voltammetry studies of some nitrophenyl- ...
