Four new complexes, namely Cd(II)(4'‐(2‐(5‐R‐thienyl))‐terpyridine) 2 (ClO 4 ) 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. Complexes 2 and 4 were further characterized by single‐crystal X‐ray diffraction analysis, which showed that the Cd(II) ions in complexes 2 and 4 are both six‐coordinated with the N 6 coordination sphere, displaying distorted octahedral geometries. The luminescence of complexes 1 – 4 was studied. Moreover, the photocatalytic properties of complexes 1 – 4 were investigated and compared with those of their parent complex Cd(II)(terpyridine) 2 (ClO 4 ) 2 .
