a UV-Vis diffuse reflectance spectra of CuSA/COFs. Steady-state PL spectra with a function of the reciprocal temperature of b CuSA/Obq-COF and c CuSA/Ace-COF; the insets display the PL spectra at varying temperatures. 2D pseudo-color maps of d CuSA/Obq-COF and e CuSA/Ace-COF, and their corresponding fs-TA spectra under several representative probe delays: f CuSA/Obq-COF and g CuSA/Ace-COF. Kinetics decay profile probed at 520 nm of h CuSA/Obq-COF and i CuSA/Ace-COF.
