Homochiral hexanuclear nickel(ii) metallocyclic structures with high activity for the photocatalytic degradation of organic dyes

Abstract

Enantiopure ligands, namely (R,R)- and (S,S)-2,2′-(1,4-phenylene) bis(4,5-dihydrothiazole-4-carboxylic acid) (H₂L^RR, and H₂L^SS) were synthesized, and homochiral metallocyclic rings {Ni₆L^RR₆(H₂O)₁₂} (1^RR) and {Ni₆L^SS₆(H₂O)₁₂} (1^SS) were obtained and their structures were determined. The complexes exhibit excellent activity for the photocatalytic degradation of organic dyes.
