Title:

NOVEL PYRROLE MONOMER, PROCESS FOR PREPARING THE SAME, AND FUNCTIONAL POLYMER FILM

Document Type and Number:

WIPO Patent Application WO/1991/005769

Kind Code:

A1

Abstract:

A compound represented by general formula (I), wherein R¿1? and R¿2? are selected so as to form a combination wherein at least one of them functions as an electron attractive group; R¿1? represents hydrogen, cyano, alkyl, either phenyl or benzyl, COR¿3? (wherein R¿3? represents an alkyl, phenyl or benzyl), or -COOR¿4? (wherein R¿4? represents hydrogen, alkyl, phenyl or benzyl); and R¿2? represents a group of formula (II), wherein Y represents an alkylene having 1 to 12 carbon atoms, phenylene, -CO-, -COO-, -COOalk.-, -COOalkO-, -COOalkN(R¿8?)-(wherein R¿8? represents an alkyl) or -alkO- (wherein alk represents an alkylene having 1 to 12 carbon atoms); Z represents -HC=CH-, -CH=NNH-, -N=N(O)-, -C=C-, -COO-, -N=N-, -S- or a direct bond; and r represents hydrogen, nitro, cyano, halogen, either alkyl or alkoxy, -COR¿5? (wherein R¿5? represents an alkyl or phenyl), -COOR¿6? or OCOR¿7? (wherein R¿6? and R¿7? represent hydrogen, alkyl or phenyl). The polymer film can interchange the various functions (light, electricity, pressure, etc.) possessed by liquid crystal molecules.
