Novel zinc phthalocyanine (ZnPc) derivatives containing tribenzonaphtho-condensed porphyrazine (see figure) are reported. As a dye for dye-sensitized solar cells (DSSCs), the highly asymmetric derivative containing tBu groups yields a 3.56 % efficiency with the highest IPCE of 60.7 % in the red/near-IR region, which is higher than that of the derivative containing nBuO groups (2.20 % with an IPCE of 22.9 %) under AM 1.5G solar irradiation.
