Polycyclic Aromatics as Promising Phosphorescence Materials

Abstract

Phosphorescent materials, as a class of functional substances with unique optical properties, demonstrate immense application potential in various fields, such as anticounterfeiting technology, information encryption, and bioimaging. Polycyclic aromatic compounds (PACs) stand out in this field as highly promising candidates, due to their unique rigid conjugated structures, diverse and tunable conformations, easily modulated bandgaps, multifunctionality, and excellent biocompatibility. This review systematically evaluates the latest research progress in PAC‐based phosphorescent materials, highlighting the innovative strategies for enhancing phosphorescence performance and the current challenges faced, to provide forward‐looking research perspectives for this rapidly evolving field of materials science.
