Two novel triarylamine- and triazine-cored porphyrin dimers were synthesized and investigated for their potential in dye-sensitized solar cells (DSSCs). Based on cyclic voltammetric analysis, highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels of the target porphyrins were found to be in an appropriate range in the TiO2-based DSSC systems. The device studies indicated the photovoltaic effects in the DSSCs based on both materials and the significant effect of their core units on the photovoltaic conversion efficiencies of the devices.

One-Pot Synthesis of Cyanuric Acid-Bridged Porphyrin−Porphyrin Dyads
Stepwise amination of cyanuric chloride (1) with 5-(4-aminophenyl)-10,15,20-triphenylporphyrin (2) and/or its zinc(II) complex (3) enables the synthesis of porphyrin-porphyrin dyads with predetermined free base-free base forms or free base-zinc and zinc-zinc metalation states. Furthermore, the use of aminopropyl-silanized silica gel as a scavenger for unwanted byproducts allowed the one-pot synthesis of title porphyrin compounds in high yield and purity with minimum use of preparative column chromatography.
