発明の名称 (英語) Polyisocyanide derivative having controlled helical main chain structure
発明の概要(英語) The object is to provide: a method for producing a polymer having a stable right-handed or left-handed helical structure from a single type of monomer in a per-selective manner and controlling the proportion between a polymer having the right-handed helical structure and a polymer having the left-handed helical structure; and a polymeric material which can be used for the formation of any of the right-handed and left-handed helical structures.
Thus, 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]

[claim2]
2. The 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]

[claim4]
4. An aromatic isocyanide derivative which is represented by the following general formula (3): (see diagramm) wherein, Ar represents a benzene ring, R **1 represents an aminocarbonyl group of an optically active alanine ester that is esterified with an alkyl group of 6 to 30 carbon atoms, and the optically active alanine is any of levorotatory (S) or dextrorotatory (R) chiral body.
