The conventional conductive thin film using porphyrin as a material forms a charge transfer complex, which has no flow of charges in the in-plane direction of the film and cannot be used as an electric conductor. The present invention provides an ultrathin film electric conductor, a power storage body, and a photoconductor.

(rphinatomolybdenum) is developed on a 0.01 M aqueous sodium hydroxide solution to form a monomolecular film, and hypochlorous acid (NaClO, 0.04%) is added to the aqueous phase.
Was added and accumulated on the quartz plate. As a result of measuring the electron spectrum, the Soret band having a peak at 420 nm in the film developed on distilled water was 470 nm for the film on the water containing hypochlorous acid.
It shows that it is red-shifted to and is oxidized. The direct current resistance of the cumulative film was 25 megohm when the electrode gap was 0.36 mm when the gold vapor deposition film was used as an electrode. When converted to resistivity, it becomes 5 ohm meters. Polarization occurred due to the applied voltage for resistance measurement to form a battery. Similar results were obtained with triaminophenyl-, tetraaminophenyl-porphyrin and also with complexes of platinum, silver and the like.
