We show that the visible light absorption of COF-505 is tunable via altering central metal ions or the dihedral angle between two adjacent ligand groups by first-principles calculations. We also found that positively charged COF-505 with Pd(ii) exhibits appreciable O–H activation of the adsorbed H2O.

Trapped States

In this paper, nanometer-sized CdO organosol was prepared by using microemulsion methods. Its electronic structure and optical properties are characterized through UV-visible light absorption, photoluminescence, and Z-scan techniques. Some newfeatures were observed. Fluorescence and nonlinear optical responses are mainly related to surface trapped states.
