So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Li, Mengke; Cai, Xinyi; Chen, Zijian; Liu, Kunkun; Qiu, Weidong; Xie, Wentao; Wang, Liangying; Su, Shi-Jian researched the compound: 1,2-Bis(diphenylphosphino)ethane( cas:1663-45-2 ).Electric Literature of C26H24P2.They published the article 《Boosting purely organic room-temperature phosphorescence performance through a host-guest strategy》 about this compound( cas:1663-45-2 ) in Chemical Science. Keywords: heterocyclic isomer host guest cocrystal room temperature phosphorescence. We’ll tell you more about this compound (cas:1663-45-2).
The host-guest doping system has aroused great attention due to its promising advantage in stimulating bright and persistent room-temperature phosphorescence (RTP). Currently, exploration of the explicit structure-property relationship of bicomponent systems has encountered obstacles. In this work, two sets of heterocyclic isomers showing promising RTP emissions in the solid state were designed and synthesized. By encapsulating these phosphors into a robust phosphorus-containing host, several host-guest cocryst. systems were further developed, achieving highly efficient RTP performance with a phosphorescence quantum efficiency (ϕP) of ~26% and lifetime (τP) of ~32 ms. Detailed photophys. characterization and mol. dynamics (MD) simulation were conducted to reveal the structure-property relationships in such bicomponent systems. It was verified that other than restricting the mol. configuration, the host matrix could also dilute the guest to avoid concentration quenching and provide an external heavy atom effect for the population of triplet excitons, thus boosting the RTP performance of the guest.
