Compound, composition and thin film

A compound represented by the following formula (DII):

• wherein Y31, Y32 and Y33 each represents a methine group;
• R31, R32 and R33 each independently represents the following formula (DII-R):
• wherein A31 and A32 each independently represent a methine group or a nitrogen atom;
• X3 represents an oxygen atom, a sulfur atom, a methylene group or an imino group;
• Q31 represents a naphthalene group;
• n3 indicates an integer of from 1 to 3;
• L31 represents *—O—, *—O—CO—, *—CO—O—, *—O—CO—O—, *—S—, *—NH—, *—SO2—, *—CH2—, *—CH═CH— or *—C≡C—;
• * indicates the position at which the group bonds to Q31;
• L32 represents a divalent linking group selected from the group consisting of —O—, —S—, —C(═O)—, —SO2—, —NH—, —CH2—, —CH═CH— and —C≡C— and a combination thereof, and when the divalent linking group contains a hydrogen atom, then the hydrogen atom may be substituted with a substituent;
• Q32 represents a polymerizable group or a hydrogen atom, and when the polymerizable group contains a hydrogen atom, then the hydrogen atom may be substituted with a substituent.
