The present study dealing with the oxidation catalysts using in laundry bleaching process comprises of the complexion of 4’‐(N‐2‐phthalonitrile‐N‐methylamino)‐2,2’:6’,2’’‐terpyridine ( 2 ) with the related MnCl 2 .4H 2 O and CoCl 2 .6H 2 O salts in ethanol to obtain 4’‐(N‐2‐phthalonitrile‐N‐methylamino)‐2,2’:6’,2’’‐terpyridine‐Mn (II) complex ( 3 ) and 4’‐(N‐2‐phthalonitrile‐N‐methylamino)‐2,2’:6’,2’’‐terpyridine‐Co (II) complex ( 4 ). Terpyridine metal complexes substituted Zinc phthalocyanines, Tetrakis [4’‐(N‐2‐phthalonitrile‐N‐methylamino)‐2, 2’: 6’, 2’’‐terpyridine‐Mn(II) complex] phthalocyaninato zinc(II) (5) and Tetrakis [4’‐(N‐2‐phthalonitrile‐N‐methylamino)‐2,2’:6’,2’’‐terpyridine‐Co(II) complex] phthalocyaninato zinc(II) (6 ) were also prepared by the tetramerization of the terpyridine‐metal complexes ( 3, 4 ) in the presence of ZnCl 2 . FT‐IR, 1 H‐NMR, 13 C‐NMR, UV‐Vis, ESI‐MS and MALDI‐MS spectra were applied to characterize the prepared compounds. 4‐nitrophthalonitrile and some other starting materials crystallized in the synthetic pathway. 4‐nitrophthalonitrile crystalizes in different morphology and 4’‐(N‐2‐ Hydroxyehyl‐N‐methylamino)‐2, 2’ : 6’, 2’’‐ terpyridine ( 1 ) crystallizes in the monoclinic, space group. The compound 2 and 3 crystallize in the monoclinic space group. The bleach performances of the prepared terpyridine complexes ( 3, 4 ) and their phthalocyanine derivatives ( 5, 6 ) were examined by the degradation of Morin dye by using online spectrophotometric method (OSM).
