Three novel organic dyes based on porphyrin derivatives were designed and synthesized for dye-sensitized solar cells, resulting in a maximum power conversion efficiency (η) of 5.14% and a maximum IPCE value of 72% for a cell based on the PZn-hT dye. The Royal Society of Chemistry 2009.
Aspects of investigating scrambling in the synthesis of porphyrins: Different analytical methods

Herein, we discuss the analyses and quantification of the different components in porphyrin mixtures, prepared from p-anisaldehyde, p-tolualdehyde, and 5-(4-bromophenyl)-dipyrromethane with acid catalysis, using NMR and HPLC. The advantages and disadvantages of these analytical methods are emphasized. Due to the similar size of a bromine atom and a methyl group it was possible to grow crystals suitable for X-ray crystallographic studies from a mixture of porphyrins, where the 4-position of the meso-phenyl rings was either substituted with methyl groups or bromine atoms. We also show that X-ray studies are inferior to NMR analysis for determining the components in a porphyrin mixture.
Convergent synthesis of multiporphyrin light-harvesting rods

, (2008/06/13)
The present invention provides a convergent method for the synthesis of light harvesting rods. The rods are oligomers of the formula A1(Ab+1)b, wherein b is at least 1, A1through Ab+1are covalently coupled rod segments, and each rod segment A1through A1+bcomprises a compound of the formula X1(Xm+1)mwherein m is at least 1 and X1through Xm+1are covalently coupled porphyrinic macrocycles. Light harvesting arrays and solar cells containing such light harvesting rods are also described, along with intermediates useful in such methods and rods produced by such methods.

We present the design of molecular materials for ultimate use in solid-state solar cells. The molecular materials are semi-rigid oligomeric rods of defined length with metalloporphyrins in the backbone and a carboxy group at one end for attachment to a su
Functionalized meso-Arylporphyrins, Precursors for the Synthesis of Oligoporphyrinyls

Lithiation and subsequent formylation of bromo-substituted tetraarylporphyrins 3a-d, prepared under Adler-Rothemund conditions, afford a mixture of the porphyrinylbenzaldehydes 4a-d and the corresponding dialdehydes (cis and trans isomer) 7a/7d and 8a/8d, which may be isolated by column chromatography.The readily available porphyrins are suitable precursors for the synthesis of oligoporphyrinyl systems which is demonstrated for the case of the novel stilbene-linked diporphyrinyl 12.Alkyl substitution of the nonfunctionalized aryl groups brings about sufficient solubility of the porphyrins in organic solvents.
