Three Cu(II/I) coordination polymers/supramolecules were obtained by means of hydrothermal synthesis: (1) [K2Cu2(ox)(btec)(MeOH)(2)](n), (2) {[Cu(pdc)(H2O)(2)]center dot H2O}(n), and (3) [Cu(cyan)(phen)]center dot H2O (where H(2)ox is oxalic acid, H4btec is 1,2,4,5-benzenetetracarboxylic acid, MeOH is methanol, H(2)pdc is pyridine-2,5-dicarboxylic acid, phen is 1,10-phenanthroline, and Hcyan is cyanuric acid). These compounds were characterized by single crystal X-ray diffraction, surface photovoltage spectroscopy (SPS), solid phase ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared (FTIR) spectroscopy, and elemental analysis. Results indicated that (1) is a three-dimensional (3D) coordination polymer while (2) is a two-dimensional (2D) coordination polymer connected into a 3D network through hydrogen bonding. For both (1) and (2), the center metal is a Cu(II) cation. Compound (3) is a Cu(I) mononuclear complex which forms a 2D supramolecule via hydrogen bonding and pi-pi interactions. The SPS data for these three complexes exhibited photovoltage responses in the range of approximately 300 to 800 nm, indicating that all three possess some capacity for photoelectric conversion. The effects of composition, structure, dimensionality, ligands, valence states, and coordination environment of the central metal ions on the SPS results were investigated and discussed, as was the interrelationship between SPS and UV-Vis spectra.
