The third approach involves: 1) the synthesis of certain molecules containing readily polarised groups of substituents, and 2) the controlled polymerisation or crystallisation of these molecules.目的首要是找到一个具相对地稳定的染料前驱体的导带，然后将这些转成所需要的染料。第三种方法包括： 1)将含极性取代基的染料分子合成；2)控制染料分子的聚合或结晶过程。 conducting chain - 导带（导带本?閏onduction band，不知是否相同，请翻查）dye precursors - 染料前驱体synthesis - 合成（dye) molecules - 染料分子polarised - 含极性substituents - 取代基polymerisation - 聚合过程crystallisation- 结晶过程********原文出自“High-temperature Exciton Superconductivity: Synthetic Aspects”（译：高温超导激子的合成），一篇由Eduard B Yagubskii在1972年发表的文章。字汇翻译参考： （并非专业翻译，仅供参考。）
