Abstract

Abstract : Two novel 2, 7-naphthyridines which are unexpectedly obtained from 2-(3, 5-diaryl-4 H -pyran-4-ylidene)malononitrile and benzylamine display phosphorescence, thermally activated delayed fluorescence, and high contrast solid-state acidochromism. Abstract : Two novel 2, 7-naphthyridine derivatives are unexpectedly synthesized by the reaction of 2-(3, 5-diaryl-4 H -pyran-4-ylidene)malononitrile and benzylamine, and are achieved through different ring-closing mechanisms. These two derivatives with twisted molecular conformations display phosphorescence, thermally activated delayed fluorescence, and high contrast solid-state acidochromism due to special chemical structures.
