<P>PROBLEM TO BE SOLVED: To provide a novel tetraphenylporphyrin derivative having a plurality of silicon-containing substituents at the phenyl groups at the meso position, to provide a porphyrin complex, and to provide dye-sensitized solar cells using them as dyes. <P>SOLUTION: The porphyrin derivative is represented by formula (1) and is synthesized by, for example, a method (the so-called Lindsey method) comprising cyclizing a silicon-containing-substituent-containing benzaldehyde derivative, a carboxylic-ester-containing benzaldehyde derivative, and pyrrole by dehydrative condensation in the presence of an acid catalyst and chemically oxidizing the product of cyclization. <P>COPYRIGHT: (C)2009,JPO&INPIT |
