General solvent-free ionic liquid catalyzed C–N/C–C coupled cyclization to diverse dihydropyrimidinones and new organic materials: Langmuir–Blodgett film study†
Abstract
An ionic liquid catalyzed dual C–N/C–C coupled cyclization of a three component assembly is demonstrated to access 3,4-dihydropyrimidin-2(1H)-one (DHPM) analogues under solvent-free green conditions. Innovative new organic materials are introduced with pure and mixed DHPM using LB high surface pressure, AFM and photophysical studies.
