Abstract Organic room temperature phosphorescent (ORTP) materials have garnered significant interest in the fields of anti‐counterfeiting, optical display, and bio‐imaging owing to their distinctive properties. However, a major drawback most existing ORTP is short phosphorescence lifetime low quantum yields (QYs), which greatly limit applicability across multiple fields. In this paper, covalently assisted host‐guest doping strategy that involves embedding three aminobenzoic acids with...
Abstract Long‐life room temperature phosphorescent (RTP) materials hold significant potential in the fields of optoelectronic devices, information encryption, and bio‐imaging due to their excellent optical properties. However, achieving multi‐color tunable RTP has proven challenging.
