Porphyrin-phthalocyanine dimer and tetramer having directly-bound &#x3c0; electron systems and production method thereof

A photo-functional molecule element having, on a substrate, a porphyrin polymer containing covalently-fixed porphyrin units, and the method of preparing the same. The photo-functional molecule element may be used as a photoelectric conversion element such as an organic solar cell or a three-dimensional, non-linear organic material.

Element having porphyrin polymer fixed on a substrate and method of preparing the same
