a Chemical structures of the investigated molecules. b HOMO and LUMO distributions of DTPPAO and tBuDTPPAO calculated at the B3LYP/6-311 G(d) level. Normalized steady-state photoluminescence (PL) emission and delayed spectra (delay time of 8 ms) of (c) DTPPAO and (d) tBuDTPPAO in different host matrices at ambient conditions. Time-resolved decay curves of (e) DTPPAO/host systems at the phosphorescence emission band of 503 nm and (f) tBuDTPPAO/host systems at the phosphorescence band of 487 nm. Insets: Photographs of guest/host systems taken under daylight, 365 nm UV lamp on and off. g The schematic of mechanism and proposed transfer paths between guest and host molecules in the doping systems.
