Anisotropic Self-Alignment of Supramolecular Amylose Inclusion of Chromophores for Second-Order Nonlinear Optical Materials
Anisotropic alignment of nonlinear chromophores and their dipolar stability are the key issues1 of nonlinear optical (NLO) materials. Poling is a usual means in guest-host systems to bring about such an alignment2-4. Since poling is carried out around the glass transition temperature(Tg) of hosts5, and the temporal stability of chromophores depends primarily on Tg values of hosts, matrix materials for high-temperature stability are required to have high Tg such as with polyimides. However, the high-temperature poling causes problems in nonlinear chromophores, such as bleaching6-7, decomposition8,9 or loss of dipolar alignment10, unless they have very high decomposition temperatures. Also, a related problelm is a plasticizing effect8,11 of chromophores which lowers the Tg of the matrix with increasing chromophore concentration.
