Abstract

Official abstract text for this publication.

Provided is a new polycyclic aromatic hydrocarbon derivative. The polycyclic aromatic hydrocarbon derivative is a derivative of a polycyclic aromatic hydrocarbon having 6 or more aromatic rings and has a substituent represented by the following formula (1). (In the formula (1), R1 and R2 are carbon atoms of the aromatic rings in the polycyclic aromatic hydrocarbon, and R3 to R5 are carbon atoms of an aromatic ring or a heterocyclic ring in a group having the aromatic ring or the heterocyclic ring. n is 0 or 1, and m is the number of substituents.)[Chemical 1]

First claim

Opening claim text (preview).

The invention claimed is: 1. A light-modulating material comprising a polycyclic aromatic hydrocarbon derivative that is a derivative of a polycyclic aromatic hydrocarbon having 6 or more aromatic rings and has a substituent represented by a following formula (3): [Chemical 3] in which R 1 and R 2 are carbon atoms of the aromatic rings in the polycyclic aromatic hydrocarbon; R 7 and R 8 are each a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an alkoxy group (with an alkyl group having 1 to 20 carbon atoms), a cyano group, a nitro group, an amino group, an acylamino group, an alkylcarbonyl group, an arylcarbonyl group, or an acetoxy group; and m is a number of substituents. 2. A polycyclic aromatic hydrocarbon derivative that is a derivative of a polycyclic aromatic hydrocarbon having 6 or more aromatic rings and has a substituent represented by a following formula (10): [Chemical 4] in which R 1 and R 2 are carbon atoms of the aromatic rings in the polycyclic aromatic hydrocarbon; R 3 and R 4 are carbon atoms of an aromatic ring or a heterocyclic ring in a group having the aromatic ring or the heterocyclic ring; R 9 and R 10 are each a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an alkoxy group (with an alkyl group having 1 to 20 carbon atoms), a cyano group, a nitro group, an amino group, an acylamino group, an alkylcarbonyl group, an arylcarbonyl group, or an acetoxy group; and m is a number of substituents. 3. The light-modulating material according to claim 1 , having a plane-direction dimension of 100 nm or less.
