Statistical analyses of the data conducted and general information on the reproducibility of experiments are mentioned in the relevant figure and table captions as applicable. ). e, Photothermal stability test for the metal precursor under green light (green outline) for 2 h (maximum and minimum temperature set at 120 °C and 100 °C respectively). Similarly, f, photothermal response of the DMF (control), DHBDC, and metal precursor under red light (red outline) exposure (maximum temperature set at 150 °C for 30 min). g, Photothermal stability test for the metal precursor under red light (red outline) for 2 h (maximum and minimum temperature set at 120 °C and 100 °C respectively). h, Photothermal activity of the MOF at various wavelength (typically at 520 nm or 660 nm) showing correspondences with the light absorption (Fig. ). i, Table the photothermal response of the molecular heater, ligand, and the MOF at two different wavelengths employed (± SD, n=number of cycles).
