“H”-shape second order NLO polymers: synthesis and characterization

Author affiliations


In this work, two “H”-shape and one “AB”-type second order nonlinear optical (NLO) polymers were prepared for the first time. The linkage positions of chromophores in the “H”-shape polymers were shoulder-to-shoulder, in which the chromophore moieties were part of the polymeric backbone. The subtle structure could be easily modified by the introduction of different isolation groups, to adjust the property of the resultant polymers. All the polymers exhibited good film-forming ability and thermal stability. The second harmonic generation (SHG) experiments demonstrated that the two “H”-shape polymers (P1 and P2) exhibited large SHG coefficients of d33 values (up to 90 pm V−1), and P2 even demonstrated relatively good long-term temporal stability.
