Nonlinear optical (NLO) polymers have been extensively studied over the past decade because of their potential applications in the field of field of electro-optic devices, including ultrafast optical switches and high-speed optical modulators. Generally main-chain NLO polymers have good thermal stability of dipole alignments, but they often do not dissolve in organic solvents, which make them unusable to fabricate stable noncentrosymmetric films. Side-chain NLO polymer systems have the advantages such as good solubility and high level of NLO chromophore relative to the main-chain systems, but they often suffer from poor stability of dipole alignments at high temperatures. In this work we prepared a new polyester containing nitrothiazolylazoresorcinoxy groups as NLO chromophores, which constitute parts of the polymer backbone. After confirming the structure of the resulting polymer, we investigated its properties. |
