<p><P>PROBLEM TO BE SOLVED: To provide a method for simply synthesizing a subphthalocyanine formed by directly coupling a central boron with carbon and having optically desirable absorption characteristics and solubility characteristics with good yield; and an optical film which uses the subphthalocyanine obtained by this method, has light resistance, heat resistance, and absorption in a specific wavelength region, and serves as excellent functional optical thin film. <P>SOLUTION: In the method of producing axially substituted boron subphthalocyanine derivatives represented by chemical formula (III), a boron subphthalocyanine halide is reacted with a compound represented by the following chemical formula (II) R'-MgX<SP>2</SP>... (II). In the formula (III), R is a group selected from hydrogen, a halogen atom, a straight/branched chain alkyl group, an aralkyl group, an aryl group, an amino group, a hydroxyl group, an alkoxyl group, a thiol group, a thioether group, a straight/branched chain alkyl group partially/fully substituted with fluorine, a straight/branched chain aralkyl group partially/fully substituted with fluorine, and an aryl group partially/fully substituted with fluorine; R' is a group selected from a straight/branched chain alkyl group, an aralkyl group, and an aryl group; and n is an integer of 1-4. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
