Abstract

Abstract : Four new complexes, namely Cd(II)(4'‐(2‐(5‐R‐thienyl))‐terpyridine)2 (ClO4 )2 (R = hydrogen (1 ), bromo (2 ), methyl (3 ), and methoxy (4 )), were synthesized and characterized by high‐resolution mass spectrometry, infrared (IR) spectroscopy, and elemental analysis. Complexes2 and4 were further characterized by single‐crystal X‐ray diffraction analysis, which showed that the Cd(II) ions in complexes2 and4 are both six‐coordinated with the N6 coordination sphere, displaying distorted octahedral geometries. The luminescence of complexes1 –4 was studied. Moreover, the photocatalytic properties of complexes1 –4 were investigated and compared with those of their parent complex Cd(II)(terpyridine)2 (ClO4 )2 .
