“…As a multifunctional dye, phthalocyanine (Pc) has received great attention for applications in numerous areas, such as pigments, [1] catalysts, [2] photoconducting agents, [3] chemical sensors, [4] optical storage materials, [5] photovoltaic cells, [6] organic semiconductors, [6c, 7] and photodynamic therapy [8] (PDT) of cancer. Among these applications, the use of Pcs as photosensitizers for PDT has attracted much more attention in recent decades because of their efficient singlet oxygen generation and intense absorption in the red and near-IR (NIR) region that is recognized to be the optimal therapeutic window with high tissue penetration for treatment of deep-seated tumors.…”

To demonstrate the effect of axial ligands on the structure-activity relationship, a series of axially substituted silicon phthalocyanines (SiPcs) have been synthesized with changes to the axial ligands. The reactivity of the axial ligand upon shielding by the phthalocyanine ring current, along with their stability, photophysical, and photodynamic therapy (PDT) activities were compared and evaluated for the first time. As revealed by single-crystal XRD analysis, rotation of the axial -OMe ligands was observed in SiPc 3, which resulted in two molecular configurations coexisting synchronously in both the solid and solution states and causing a split of the phthalocyanine α protons in the (1)H NMR spectra that is significantly different from all SiPcs reported so far. The remarkable photostability, good singlet oxygen quantum yield, and efficient in vitro photodynamic activity synergistically show that compound 3 is one of the most promising photosensitizers for PDT.
