Synthesis characterization and metal sensing applications of novel chalcone substituted phthalocyanines

•The synthesis of new chalcone substituted metallophthalocyanines.•Synthesize and characterization of phthalocyanines carrying four chalcone groups.•Metal titration with phthalocyanine.•Metal sensing ability of phthalocyanine.

The synthesis of novel metallophthalocyanines (M = Zn, Co) bearing (E)-3-(4-hydroxyphenyl)-1-phenylprop-2-en-1-one as chalcone on four of the peripheral positions were achieved. These complexes have been characterized by a combination of FT-IR, 1HNMR, HRMS and UV–vis spectroscopytechniques and all the new compounds are highly soluble in most common organic solvents. In addition, metal ion binding titration properties are investigated. Cu+2 and Fe+3 ions were used for titration. The titration results give us the opportunity for application of metal sensing studies of phthalocyanines.
