Syntheses and photophysical properties of rigid-rod conjugated compounds based on N-7-azaindole and 2,2′-dipyridylamine

Rigid-rod conjugated compounds based on N-7-azaindole and 2,2′-dipyridylamine functional groups have been synthesized as potential compounds for molecular electronic devices via Pd-mediated Sonogashira couplings. Their photoluminescent properties have been investigated.
