Structural and mechanistic insights into an Fe3+-triggered quinazoline based molecular rotor†
Abstract
Highly fluorescent, multifunctional and thermoreversible conformational switching (1) has been designed and developed by embedding two imidazo[1,2-c]quinazoline (IQ) units in the pyridyl scaffold. The origin of the conformational and optical switching of 1 to 1′ has been established by various studies and by developing a model compound.
