Abstract
Various highly fluorescent acridinediones were synthesized by microwave and ultrasound irradiations, as well as by conventional thermal methods. It was found that most of the acridinedione derivatives could be obtained in very high yields (80~90%) in the microwave- assisted, solvent-free, one-pot synthesis process within minutes (~2 min). These highly fluorescent acridinediones are potential new materials for electroluminescence (EL) devices.
