Abstract

A chiral three-dimensional polyoxometalate cluster− organic framework (POMCOF) H₃[(btc)Ni₆(μ₃-OH)₃(H₂O)₅(B-αPW₉O₃₄)]·17H₂O (1, btc = 1,2,4-benzenetricarboxylate) has been made under hydrothermal conditions in the absence of amine or chiral starting reagents. 1 shows high stability in CH₃CN/DMF (1:3), acidic, and basic solutions with the pH ranging from 2 to 12 for 5 days. The UV−vis reflectance spectra and Mott−Schottky measurements reveal that 1 could be a suitable catalyst for photocatalysis. Visible-light-driven H₂ evolution studies have demonstrated that 1 is an ecofriendly, efficient, and recyclable catalyst with a H₂ evolution rate of 1058.24 μmol h⁻¹g⁻¹. Nonlinear optical (NLO) measurement reveals that 1 exhibits a second-harmonic generation (SHG) response of about 1.4 times that of KH₂PO₄ (KDP), indicating that 1 is a potential NLO material as well.
