LIGHT REGULATING MATERIAL AND LIGHT REGULATING FILM Russian patent published in 2011 - IPC C09K9/02 G02B5/22 

FIELD: chemistry.

SUBSTANCE: resin is a polyacetylene compound, having a repeating unit of general formula (1) . In formula (1) R¹ denotes a naphthalene group, phenanthrene group, pyrenyl group or anthracene group. Each of these four groups is a substituted group selected from: alkyl group, alkoxy group, a SR⁴ group (R⁴ denotes a hydrogen atom or an alkyl group), a NR⁵R⁶ group (R⁵ and R⁶ each denote a hydrogen atom or a group selected from alkyl groups), cyano group, carboxy group, sulphoxyl group, ester group, amide group and COR⁷ (R⁷ denotes an alkyl group, having 1-40 carbon atoms), or the following general formula (2) . In formula (2), R² denotes a naphthalene group or an anthracene group; R³ denotes a phenyl group substituted with a substitute X in position m or position p; and substitute X is a group selected from: alkyl group, alkoxy group, SR⁴ group (R⁴ denotes a hydrogen atom or alkyl group), a NR⁵R⁶ group (R⁵ and R⁶ each denote a hydrogen atom or a group selected from alkyl group), cyano group, carboxy group, sulphoxyl group, ester group, amide group and COR⁷ (R⁷ denotes an alkyl group).

EFFECT: production of light regulating material capable of selectively controlling transmission of light in an arbitrary wavelength range from a wide wavelength range.
