NOVELTY - A functional film comprises a combination of a compound having conjugated group and coordinated group, and a metal salt of transition metal e.g. silver, cadmium, indium, tin, antimony, lanthanum, cerium, europium, hafnium, tantalum, tungsten, rhenium, osmium, iridium, platinum, gold, mercury, thallium, lead and bismuth. A curve representing the light absorption spectrum of the combination in first order differential form does not have a minimum value at 430-800 nm which is less than a quarter of the maximum value at 240-400 nm.    USE - Functional film is used for electric-charge injection layer and charge transferring layer of organic electronic devices e.g. organic light-emitting elements, organic transistor elements and organic photoelectric conversion elements (all claimed) e.g. organic solar cells.    ADVANTAGE - The functional film has excellent electric-charge-injection function and charge-transfer function. The combination forms a network between molecules and improves the injection property of electric charge from a metal electrode and the mobility of electric charge. The functional film provides organic electronic devices having excellent luminous efficiency.    DETAILED DESCRIPTION - A functional film comprises a combination of a compound of formula: Ar-(-J)n having conjugated group and coordinated group, and a metal salt of transition metal chosen from aluminum, scandium, titanium, vanadium, chromium, manganese, zinc, gallium, germanium, yttrium, zirconium, niobium, molybdenum, ruthenium, palladium, silver, cadmium, indium, tin, antimony, lanthanum, cerium, europium, hafnium, tantalum, tungsten, rhenium, osmium, iridium, platinum, gold, mercury, thallium, lead and bismuth. A curve representing the light absorption spectrum of the combination in first order differential form does not have a minimum value at 430-800 nm which is less than a quarter of the maximum value at 240-400 nm.    Ar=n-valent conjugated group;    J=monovalent coordinated group having 1-8 atoms which can be coordinated to the metal ion which constitutes the metal salt, with the atoms being two or more chosen from carbon, nitrogen, oxygen and sulfur, preferably nitrogen;and    n=2-20.    INDEPENDENT CLAIMS are included for the following:    (1) organic electronic device provided with the functional film, and electrode(s) provided on the both sides of the functional film directly or through another layer;    (2) fluorene-type compound of formula (I); and    (3) complex of formula (II) consisting of the fluorene type compound and the transition metal salt.    R=monovalent hydrocarbyl;    J1=monovalent coordinated group having 1-3 atoms which can be coordinated to zinc ion, preferably bipyridyl, terpyridyl or phenanthrolinyl;    (AN)(power)(n'-)=n'-valent counter anion;    n'=1 or 2;and    dotted line=1-3 coordinated bonds.
