a Photocatalytic CO2 reduction with PAHs under the illumination of a 300 W Xenon lamp (50 mw cm−2, λ > 400 nm, irradiation time: 18 h) in the presence of PAHs (10 μM), CAT (5 μM), BIH (18 mM) and TEA (0.3 mM) in 5 mL CO2-saturated CH3CN/H2O (v/v = 4/1) solution. b Nanosecond transient absorption spectra of kinetic decay trace of TP, TPy, and TH at 500 nm. These spectra were recorded in CH3CN/H2O (v/v = 4/1) solution after pulsed excitation at 430 nm under argon atmosphere at room temperature. c Delayed emission spectra of TPy@PS at mass ratio of 1:75 in air and vacuum. d Phosphorescence efficiency of PAHs@PS at mass ratio of 1:75.
