摘要

Luminescent materials with room-temperature phosphorescence (RTP) have drawn tremendous attention due to their remarkable advantages, such as long emission wavelength and lifetime, large Stokes shift, and high signal-noise ratio.Currently, most RTP materials are inorganics or organometallic complexes containing expensive and toxic noble metals.To promote the development of the field of RTP, it is necessary and important to design and prepare metal-free RTP materials because of their potential applications in molecular switches, anti-counterfeiting, chemical sensors and biological imaging, etc.[1].
