PROBLEM TO BE SOLVED: To provide a photoenergy transferable element obtained by forming a self- organized monomolecular film composed of a mixture of an energy donor and an energy acceptor compound of the surface of a substrate. SOLUTION: This photoenergy transferable element obtained by forming a monomolecular film from a donor compound of formula A: E-L-Bin. ...A [E is a light-absorbing organic residue; L is an atomic group having a long chain of (CH2)n [(n) is, for example, 1 to 20] or an atomic group whose main chain is divided with O, S or N and binds to E or EA through NH-CO, O or CO-O; Bin is a group for binding the compound A or B to the surface of a metal or a semiconductor through a covalent bond or a coordination bond] and an acceptor compound of formula B: EA-L-Bin. ...B [EA is a light-absorbing organic group having an absorption wave length region overlapping with the exciting light of the compound of formula A] on the surface of the metal or semi-conductor formed on the surface of a substrate through covalent bonds or coordination bonds in a state that energy can be transferred between both compounds.
