Bathochromic thiazolylazo second-order nonlinear optical chromophores
(NLOphores) having 2-hydroxyethyl group(s) in a molecule have been pre
pared. The tris(2-hydroxyethyl) derivatives showed the best relaxation
behaviour among the non-, mono-, bis- and tris(2-hydroxyethyl) ones d
oped in poly(methyl methacrylate-co-methacrylic acid). (C) 1998 Elsevi
