Fig. 2: Photophysical properties for the adaptive host–guest materials of PTZ/TA, PTZ/PXT, and PTZ/XT under ambient conditions.
From: Boosting organic phosphorescence in adaptive host-guest materials by hyperconjugation
a Steady-state photoluminescence (dash line) and phosphorescence (solid line) spectra with a decay time of 8 ms. Inserts: photographs of the phosphors under a 365 nm lamp on (left) and off (right). b CIE coordinate diagram of phosphorescence. c Lifetime decay profiles of emission bands at 498, 508, and 517 nm. The average lifetimes are also listed. d Excitation-phosphorescence emission mapping of PTZ/PXT. e Histogram of phosphorescence quantum yields. Doping concentrations were 0.5 mol% for PTZ/TA, 1.0 mol% for PTZ/PXT and PTZ/XT, respectively.
