PURPOSE:To provide the subject thin film exhibiting high photoelectric transfer characteristics and capable of being applied to photodiodes, solar batteries, photosensors, etc., by piling single molecule films containing a specific porphyrin derivative on a conductive substrate. CONSTITUTION:Single molecule films containing a porphyrin derivative of formula I or II (Ar is an aromatic hydrocarbon which may be substituted; R is 14-30C long chain alkyl; M is two valent anion mainly comprising a metal atom; X is anionic group) are piled on a conductive substrate e.g. prepared by forming the thin film of a metal (oxide) on an insulating substrate such as glass or quartz in a thickness of usually 10-2000Angstrom to provide the objective thin film. |
