Abstract A phthalonitrile derivative 4-{4-[(E)-(thiophen-2-ylmethylidene)amino]phenoxy}phthalonitrile (2) and its Co(II) and Cu(II) phthalocyanine derivatives (2a, 2b) are reported. The compounds have been characterized by spectroscopic techniques (IR, NMR, UV–Vis, and MS) and elemental analyses (for the metallophthalocyanines). Photocatalytic activities of 2a and 2b on 4-nitrophenol (4-NP) oxidation are reported. Parameters influencing the photooxidation process were determined; 4-NP oxidizes to less harmful products with high conversion and yield in the presence of Co(II) and Cu(II) phthalocyanine catalysts.
