Preparation of the Inclusion Complex-Type Nonlinear Optical Polymer

Abstract

is study uses the inclusion complex method to import nonlinear optical (NLO) chromophores, disperse red1 (DR1), and spiropyran (SP), into the -CD cavity of the -cyclodextrin polymer ( -CDP) to prepare orderly aligned nonphotocontrollable and photocontrollable nonlinear optical polymers. Calculations support the ultraviolet/visible analyses and suggest the formation of the 1 : 2 DR1/ -CDP and 1 : 2 SP/ -CDP inclusion complexes. Upon complexation, the DR1 and SP molecules are free to align themselves along an applied electric �eld and show high order parameters of approximately 0.48 and 0.20, respectively. Reversible photochromic reactions exhibit that the SP/ -CDP complex still retains the photochromic properties following corona poling.
