Novel peripheral and nonperipheral tetrasubstituted zinc(II) phthalocyanines with ester-containing coumarin substituents: Synthesis, characterization, aggregation, thermal and antioxidant studies. Journal of the Iranian Chemical Society, 23(3), pp. 1-13. https://doi.org/10.1007/s13738-026-03369-21735-24281735-207Xhttps://doi.org/10.1007/s13738-026-03369-2https://hdl.handle.net/20.500.13055/1387In this study, nonperipheral and peripheral zinc metallophthalocyanine compounds substituted with coumarin contain ing ester groups were synthesized, their chemical structures were characterized, and their aggregation behaviours were investigated. Their antioxidant properties were investigated using 1,1-diphenyl-2-picrylhydrazine (DPPH). The antioxidant activity studies revealed that the peripheral substituted phthalocyanine compound had higher antioxidant activity than the nonperipheral phthalocyanine compound. Their thermal analysis were investigated using thermal gravimetric analy sis. Thermal analysis studies concluded that the synthesized zinc metal phthalocyanine compounds are thermally stable compounds.eninfo:eu-repo/semantics/closedAccessMetallophthalocyanineAggregationThermal PropertiesAntioxidant ActivityArticle10.1007/s13738-026-03369-2233113Q3WOS:0016981978000022-s2.0-105030949620Q2
