The acetylene polymer type material null constitutional formula where the extinction emission spectrum changes

摘要

Structural formula(N in formula is integer of 30, or more as for R, -c6h4-oc _xH2x+1, -c6h4-n=ncoc _xH2x+1 and -c6h4-nhcoc _xH2x+1, o- trifluoromethyl phenyl or o- (2- chieniru) it is phenyl, as for X correct integer, as for -c6h4- o-, it is the m- or p- phenylene basis,) with being the polymer which is displayed, the molecular chain has systematic narasen structure, offers the form of the extinction emission spectrum and the polymer where peak wave length changes reversibly due to the fact that pitch of helical structure changes reversibly with the grant, solvent processing or the change of stimulus.
