Abstract

Molecular sensors are molecules that interact with substances of interest and produce a detectable change. Therefore, their unique properties have been applied in various field. This paper aims to study whether structural changes are required for the molecular sensor 5-propionyl-1-dimethylaminonapthalene to reach its charge transfer excited state. After examining the solvatochromism, quantum yield, and hydrogen bond quenching data between 5-propionyl-1-dimethylaminonapthalene and 1-(1-methyl-1, 2, 3, 4-tetrahydronaptho[1, 8-bc] azepin-7-yl) propan-1-one, this paper concludes that 5-propionyl-1-dimethylaminonapthalene fluoresces through a planar ICT and the carbonyl group is sensitive to hydrogen bond quenching.
