利用Ｗｉｔｔｉｇ反应合成了超文化ＰＰＶ及线性ＰＰＶ（包括对位和间位ＰＰＶ），产物经ＦＴＩＲ，１Ｈ－ＮＭＲ，１３Ｃ－ＮＭＲ，凝胶渗透色谱（ＧＰＣ）等手段进行了表征，研究了它们在溶液和薄膜状态下的光物理性质．在二氯甲烷溶液中，超支化ＰＰＶ和具有间位结构的线性ＰＰＶ的最大吸收和发射波长的位置基本相同，都在对位ＰＰＶ吸收和发射的短波方向．说明超文化ＰＰＶ分子的电子结构与对位ＰＰＶ明显不同，处在一种特殊的共轭结构形式．与溶液状态相比，超文化和间位ＰＰＶ的膜的吸收都发生了不同程度的蓝移，而发射却发生了红移．但是相应的对位ＰＰＶ的膜与溶液状态相比，无论是吸收和发射都发生了不同程度的红移，说明超支化ＰＰＶ分子的能级结构比较特殊
The hypercultural PPV and linear PPV (including para and meta PPV) were synthesized by Wittig reaction. The products were characterized by means of FTIR, 1H-NMR, 13C-NMR and gel permeation chromatography (GPC) Photophysical Properties in Solution and Film Conditions. In dichloromethane solution, the positions of maximum absorption and emission wavelength of hyperbranched PPV and linear PPV with meta structure were almost the same, all in the short-wave direction of absorption and emission of para-PPV. It shows that the electronic structure of PPV is obviously different from that of para PPV and is in a special form of conjugate structure. Compared with the solution state, the absorption of the membrane of meta-culture and meta PPV all experienced different degrees of blue-shift, but the emission shifted red-shifted. However, compared with solution state, the corresponding para-PPV membranes both red-shifted in both the absorption and emission, indicating that the energy structure of hyperbranched PPV molecules is rather special
