摘要
具有优良电致发光性能的有机聚合物材料的研制及其发光性能和应用的研究是９０年代新兴的高科技领域．聚对苯乙炔［Ｐｏｌｙ（ｐ－ｐｈｅｎｙｌｅｎｅｖｉｎｙｌｅｎｅ），缩写为ＰＰＶ，又称聚苯撑乙烯］是这一领域最先研制出来的具有代表性的材料［１，２］．为改变ＰＰ...
In this contribution, how to prepare the electroluminescence materials of Poly(PV co DMeOPV) based on Wessling solutable precusor route was described. The determined spectrum shapes of the PL and EL of co polymer having 1∶1 mole ratio all are single peak type, and different from the double peak shapes of PL and EL spectra of PPV. And the emissive maximum magnitudes of PL and EL of above co polymer are 520 nm and 570 nm, respectively. The PL peak lies on about middle position between 515 nm and 601 nm which are the PL short wave peaks of PPV and PDMeOPV, respectively. For the sake of discussing the influence of co polymerization on luminescence property of co polymer, the EHMACC/CO(Crystal Orbital) program is used to calculate the energy bands of PPV, PDMeOPV and 1∶1 molar ratio co polymer. The results show that due to the p π conjugation between the OCH 3 and the main chain, the energy gap of co polymer decreases, and the emission spectrum is red shift; this kind of effect will become stronger and stronger with the increasing of OCH 3 number on the conjugative chain.
