Atom Effect

Pure organic room-temperature phosphorescence (RTP) materials have attracted wide attention for their easy preparation, low toxicity and applications in professional fields such as bioimaging and anti-counterfeiting. Developing phosphorescent systems with more universality and less difficulty in synthesis has long been the pursuit of materials scientists. By employing polymeric quaternary ammonium salt with an ionic bonding matrix and heavy atoms, commercial fluorescent dyes are directly endowed with phosphorescence emission. In a single amorphous polymer, the external heavy-atom effect generates excited triplet states, which are further stabilized by the rigid polymer matrix. This study proposed a new general strategy to design and develop pure organic RTP materials starting from the vast library of organic dyes without complicated chemical synthesis.
