Following modification, click reaction was performed by adding 10 mg of ZnPc (1.04×10 -2 mol) (Cu(PPh3)3Br) (50 mg, 0.054 mmol), 100 µL of azidothiol-AuNPs, 0.5 mL DMF, and 0.5 mL triethylamine. TBAF (1 M, 0.66 mL) was added dropwise (the first portion of 0.11 mL over 1 h and the second portion of 0.55 mL over 1.5 h), and the reaction mixture was stirred for 72 h under nitrogen atmosphere. The product was washed with MeOH three times and dried at room temperature for characterization.
