Ultrasound-accelerated synthesis of quinoline-based luminescent imines exhibiting large Stokes shift

摘要

High yield synthesis of quinoline-based fluorescent imines, exhibiting the highest Stokes shift exceeding 380 nm ( 18 000 cm(-1)), is reported in the current publication. Such large difference in the excitation and emission wavelengths is quite unusual. Synthesis of imines was accelerated by ultrasound. Both experimental and theoretical studies have been performed.
