発明の名称 (英語) Polyisocyanide derivative having controlled helical main chain structure
発明の概要(英語) (US7619109)
Disclosed are: a method for production of a polyisocyanide derivative having a stable helical main chain structure with a right-handed or left-handed helix or a mixture thereof from a single type of monomer by polymerizing an aromatic isocyanate having a substituent harboring a structure -CONH in the aromatic ring and a hydrophobic moiety having 6 or more carbon atoms in a polymerization solvent, wherein the direction of the helix depends on the polarity of the polymerization solvent; a poly(aromatic isocyanide) derivative produced by the method; and an aromatic isocyanide which is useful as a monomer for use in the production of the poly(aromatic isocyanide) derivative.
特許請求の範囲(英語) [claim1]
1. A polyaromatic isocyanide derivative having a helical main chain structure represented by the following general formula (1):
wherein, Ar represents a benzene ring of 6 to 30 carbon atoms, R1 represents an aminocarbonyl group of an optically active alanine ester that is esterified with an alkyl group of 6 to 30 carbon atoms, the optically active alanine is any of levorotatory (S) or dextrorotatory (R) chiral body, and x is a positive number indicating the repeat of polyisocyanide group.
[claim2]
2. A polyaromatic isocyanide derivative according to claim 1 wherein the polyaromatic isocyanide derivative is a polyaromatic isocyanide derivative which can form a hydrogen bond between the adjacent amide groups on a side chain.
[claim3]
3. A polyaromatic isocyanide derivative according to claim 1 wherein the polyaromatic isocyanide derivative has a persistence length of 100 nm or more.
[claim4]
4. A liquid crystalline composition comprising a polyaromatic isocyanide derivative of claim 1.
