In thisstudy,thesynthesisofphthalonitrilederivativesbearing fluoro-functionalizedgroupsandtheirperipherally-tetrasubstitutedzincphthalocyaninecomplexeswerereported.Thephthalonitrilederiva-
tives 2a–5a werepreparedbynucleophilicsubstitutionof4-nitrophthalonitrilewith2-[3-(trifluoromethyl)phenoxy]ethanol,2-{2-[3-(trifluoromethyl)phenoxy]ethoxy}ethanol,2-(2,3,5,6-tetrafluorophenoxy)ethanol,2-[2-(2,3,5,6-tetrafluorophenoxy)ethoxy]ethanol,respectively.Zincphthalocyanines
bearing fluoro-functionalizedgroups(2b–5b) wereobtainedfromthecorrespondingphthalonitrile
