Abstract

Reaction of tetraphosphine (P4) ligand dppbpda with Ag(I) oxylates yielded new coordination polymers (CPs) of formula [(dppbpda)Ag₄(Ox)₄]_n (Ox=Bz (1), Sal (2), LA (3), Bz=benzoate, Sal=salicylate, LA=lactate). The solid-state structures of 1–3 consist of one dimensional (1D) chains constructed from tetranuclear μ-η²,η²- connected Ag₄(Ox)₄ cluster cores and dppbpda bridging ligands. Compounds 1–3 absorbed Congo Red in two distinct steps, with maximum uptake quantities of 1438 (1), 1417 (2) and 1656 (3) mg/g, inversely correlating with the size of the anions in the CPs. These CPs had band gaps in the semiconducting region (Eg) 3.05–3.15 eV and all three showed enhanced two-peak photocurrent responses during the stepwise adsorption of CR, with maximum photocurrent densities of 227 (1), 163 (2) and 386 (3) μA cm⁻² for composites with optimized dye coverage.
