Paragraph 0249; 0253-0254, (2021/08/06)
A composition contains a naphthalocyanine derivative represented by the following formula: where R1 to R8 are independently an alkyl group and R9 to R12 are independently an aryl group, and at least one hydrogen atom in at least one selected from the group consisting of R9, R10, R11, and R12 is substituted by an electron-withdrawing group.

The synthesis and characterization of 30 Al, Ga, Si, and Sn naphthalocyanines relevant to the search for improved photodynamic therapy agents are reported. The compounds that have been studied are AlNcCl, AlNcOH, AlNcOSi-(n-C6H13)3, (AlNcF)n, GaNcCl, GaNcOH, GaNcOH·2H2O, GaNcOSin-C6H13)3, (GaNcF)n, SiNc(O-n-C8H17)2, SiNc[(OCH2CH2)～17OCH3] 2, SiNc[(OCH2CH2)～43OCH3] 2, SiNc[4-OCH2CH2)～26OC6H 4C(CH3)2CH2C(CH3) 3]2, SiNc[4-OC6H4CO(OCH2CH2) 3OCH3]2, SiNc[OSi(n-C4H9)2(n-C18H 37)]2, SiNc[OSi(i-C4H9)2(n-C18H 37)]2, SiNc[OSi(CH3)2(CH2)10COOCH 3]2, SiNc(2/3-Cl)4Cl2, SiNc(2/3-Cl)4(O-n-C8H17)2, SiNc(2/3-Cl)4[OSi(n-C6H13)3] 2, SiNc[2/3-Cl)4(OH)2, SiNc(2/3-Br)4Cl2, SiNc(2/3-Br)4(O-n-C8H17)2, SiNc(2/3-Br)4[OSi(n-C6H13)3] 2, SiNc(2/3-Br)4(OH)2, SnNcCl2, SnNc, SnNcI2, SnNc(OH)2, and SnNc[OSi(n-C6H13)3]2. For nine of these compounds and for an additional compound, SiNc[OSi(n-C6H13)3]2, one or more of the following photoproperties have been determined: λQ, the Q(0,0)-band absorption maximum; ΦT, the triplet-state quantum yield or ΦT′, an approximation of ΦT; Δ∈T the triplet-minus-ground-state extinction coefficient difference at 590 nm; τT, the triplet-state lifetime in the absence of O2; and kox, the bimolecular rate constant for the quenching of the triplet state by O2. The values obtained show that λQ is essentially independent of the kinds of atoms in the 2 and 3 positions of the macrocycle and that ΦT is moderately and directly dependent on the atomic numbers of the atoms in the center and the 2 and 3 positions of the ring. In the case of the silicon naphthalocyanines, they show in addition that λQ, ΦT′, and τT are moderately dependent on the type of axial ligand present.
