Lead(II)-Based Coordination Polymer Exhibiting Reversible Color Switching and Selective CO2 Photoreduction Properties<\/p>\n

Herein, we report a new photofunctional Pb\u2013S-based coordination polymer (CP) with the formula [Pb(ATAT)(OAc)]n<\/i><\/sub> (ATAT = 3-amino-5-mercapto-1,2,4-triazole, OAc = acetate, CP1<\/b>). Apart from its photoactive one-dimensional (1D) (\u2212Pb\u2013S\u2212)n<\/i><\/sub> chain, CP1<\/b> is also composed of another 1D (\u2212Pb\u2013O\u2212)n<\/i><\/sub> chain that originates from the coordination with acetate. The coordinated acetate can be exchanged with water (H2<\/sub>O) or dimethyl sulfoxide (DMSO), leading to the formation of a CP1\u2013H<\/b>2<\/b><\/sub>O<\/b> or CP1\u2013DMSO<\/b> structure that exhibits a distinct change in optical properties, including a white-to-yellow color change. The structural transformation of CP1<\/b> to CP1\u2013H<\/b>2<\/b><\/sub>O<\/b> and CP1\u2013DMSO<\/b>, and its subsequent recovery to the original CP1<\/b> structure could be controlled by the presence or absence of acetic acid vapor; the transformation was completely reversible. CP1<\/b> absorbed light with wavelengths shorter than 390 nm, with an estimated bandgap of 3.18 eV. Density functional theory calculations indicated that the valence band of CP1<\/b> is mainly formed by N and S orbitals originating from the ATAT unit, whereas the conduction band is composed of the Pb orbitals. Even without any modification, such as the incorporation of a molecular catalyst, CP1<\/b> reduced CO2<\/sub> into formate under UV light with >99% selectivity.<\/p>\n
