a Photographs of X-CPDs-n (n = 2–8) before and after turning off the UV lamp (365 nm) at room temperature. b Delayed emission spectra of CMX and X-CPDs-n (n = 2–8) (excitation wavelength: 365 nm, delay time: 1 ms). c The CIE coordinate diagrams plotted from the delayed spectra of X-CPDs-n (n = 2–8). d The phosphorescence lifetime decay curves of X-CPDs-n (n = 2–8). e Phosphorescence quantum yield of X-CPDs-n (n = 2–8). f Time-dependent phosphorescence mapping of X-CPDs-3 excited by 365 nm at room temperature. g Delayed emission spectra of X-CPDs-3 with varying delayed times excited by 365 nm at room temperature (interval of 200 ms). h Trajectory of TDPC of X-CPDs-3 in the CIE coordinate diagram at room temperature.
