Azulene is a nonbenzenoid aromatic hydrocarbon that consists of an edge sharing combination of five- and seven-membered carbon rings. Azulene-containing substances often exhibit unusual photophysical properties due to their emission from the second singlet excited state, which violates Kasha’s Rule. This presentation will discuss the synthetic accessibility, molecular and electronic structures, reactivity, as well as photoluminescent behavior of several mercaptoazulenes and their complexes with monovalent gold. These compounds constitute attractive platforms for developing new, relatively non-toxic, photoluminescent materials for possible applications in optical sensing.
