several triphenylmethane derivative-based single-component phosphors that possess multicolor and ultralong lifetime (1.17 s) are reported. The emission color can be tuned from cyan (460 nm) to orange-red (626 nm) through altering the excitation wavelength. Theoretical calculation studies and X-ray crystal structures reveal that clustered molecules are the reasons for the color-tunable emission. Furthermore
