Abstract

Through a facile one-pot three-component reaction and a subsequent acetylation strategy, a novel greenish-blue fluorescent 4-imino-4H-pyrido[1,2-a]pyrimidine-3-carbonitrile (IPPC) was synthesized. Electrochemiluminescence (ECL) of IPPC was firstly found to produce efficient emission at 500 nm with reducing coreactants. Its very similar ECL and PL spectra suggest that ECL production is mainly from the monomeric excited states.
