The present invention aims to provide a light control material capable of optionally controlling the light transmittance in an arbitrary wavelength range among a wide wavelength range, and a light control film formed by using the light control material. The present invention provides a light control material, which comprises a stimulus sensitive resin and is capable of controlling the light transmittance in a specific wavelength range, the stimulus sensitive resin being a polyacetylene compound having a repeating unit represented by the following general formula (1): [Chemical Formula 1] (see formula 1) in the formula(1), R1 represents a naphthalene group, a phenanthrene group, a pyrenyl group or an antheracene group, each of the four groups being substituted by a group selected from the group consisting of: an alkyl group having 1 to 40 carbon atoms, an alkoxy group (with an alkyl group having 1 to 40 carbon atoms), an SR4 group (R4 represents a hydrogen atom or an alkyl group having 1 to 40 carbon atoms), an NR5R6 group (R5 and R6 may be the same or different, and each represents a hydrogen atom or a group selected from alkyl groups having 1 to 40 carbon atoms), a cyano group, a carboxy group, a sulfoxyl group, an ester group, an amide group and COR7 (R7 represents an alkyl group having 1 to 40 carbon atoms), or the following general formula (2): [Chemical Formula 2] (see formula 2) in the formula (2), R2 represents a naphthalene group or an anthracene group; R3 represents a phenyl group substituted 39 by a substituent X at the position m or the position p; and the substituent X represents a group selected from the group consisting of: an alkyl group having 1 to 20 carbon atoms, an alkoxy group (with an alkyl group having 1 to 20 carbon atoms), an SR4 group (R4 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms), an NR5R6 group (R5 and R6 may be the same or different, and each represents a hydrogen atom or a group selected from alkyl groups having 1 to 20 carbon atoms), a cyano group, a carboxy group, a sulfoxyl group, an ester group, an amide group and COR7 (R7 represents an alkyl group having 1 to 20 carbon atoms). |
