biostudies-literatureUnknown14(17)Ding HTriarylboranes-based pure organic room-temperature phosphorescence (RTP) materials are rarely investigated because of their large steric hindrance and the electron defect of the boron atom. As a result, creating functional triarylborane RTP materials is difficult. Herein, we report the first photo-activated RTP materials with lifetimes/quantum yields ≤0.18 s/6.83% based on donor (D)-π-acceptor (A) from methylene carbazole-functionalized aminoborane (BN)-doped polymethyl methacrylate (BN-<i>o</i>-Met-Cz@PMMA) under 365 nm UV irradiation (30 s). Incredibly, BN-<i>o</i>-Met-Cz@PMMA films exhibited unprecedented photo-activated RTP dual-response properties (<i>e.g.</i>, air + 365 nm: <i>τ</i> _P = 0.18 s, <i>Φ</i> _P = 6.83%; N₂ + 365 nm: <i>τ</i> _P = Chemical science4633-4640https://www.ebi.ac.uk/biostudies/studies/S-EPMC10155920biostudies-literatureTime-dependent photo-activated aminoborane room-temperature phosphorescence materials with unprecedented properties: simple, versatile, multicolor-tuneable, water resistance, optical information writing/erasing, and multilevel data encryption.PMC10155920Yue SPeng YDing HTang MWen JWang SLi FZheng LSun YShi YCao QfalseTime-dependent photo-activated aminoborane room-temperature phosphorescence materials with unprecedented properties: simple, versatile, multicolor-tuneable, water resistance, optical information writing/erasing, and multilevel data encryption.Triarylboranes-based pure organic room-temperature phosphorescence (RTP) materials are rarely investigated because of their large steric hindrance and the electron defect of the boron atom.
