Graphycal Abstract: This study presents the synthesis of a novel polymer analogue derived from aminomethyl zinc phthalocyanine (AmPcZn) and chitosan (CH). The polymer was produced by grafting AmPcZn onto chitosan using ethyl chloroformate as a coupling agent. The resulting CH–AmPcZn polymers, containing 10%, 20%, 30%, and 60% AmPcZn, were characterized using FTIR and UV-Vis spectroscopy. The UV-Vis analysis showed that absorbance increased with higher concentrations of AmPcZn in the CH–AmPcZn solutions.
