摘要：

The resistless process of the photochemical formation of nonlinear optical pattern in the polymer layer was elaborated. The illumination of the polymer donor-acceptor layers consisting of poly(hydroxyaminoester) as a donor and tetrabromomethane as an acceptor provides second harmonic generation (SHG) due to the photochemical formation of the Michler's hydrol blue like fragment (MHB+). The square root of the SH intensity, I-0.5, linearly increases with the increase of exposure dose in region H less than or equal to 120 mi cm(-2). SHG is absent on unexposed areas of the same layer. SHG arises due to transformation of the geometry of MHB+ cation from centrosymmetric to noncentrosymmetric because of bond-length alternation under influence of Br- counteranion.
