| 摘 要： | 以ＦｅＣｌ３为催化剂，通过氧化偶联反应合成了在一般有机溶剂中完全可溶的聚（２，５－二庚氧基对苯撑）（ＨＯ－ＰＰＰ），其平均聚合度Ｐｎ＝１０。使用＾１Ｈ－ＮＭＲ、ＩＲ手段对其结构进行了表征。ＨＯ－ＰＰＰ在ＵＶ－Ｖ１ｓ谱图上的最大吸收峰位于２４２ｎｍ（Ｅ１吸收带）和３３５ｎｍ（Ｅ２吸收带）。Ｅ２吸收带相对于未取代的聚对苯撑（ＰＰＰ）产生的了较强的红移（约３５ｎｍ），根据吸收边计算其π→π＾＊跃迁的禁带

| Abstract: | Poly(2,5-diheptyloxy-1,4-phenylene)(HO-PPP) which is soluble in common organic solvent has been synthesized by oxadition coupling using iron(III) chloride as catalyst.A average degree of polymerization (WTFXP n) is about 10.The maxium absorption in UV-Vis spectra is located at 242nm (E1 absorption band) and 335nm (E2 absorption band).The E 2 band occurs about a 35nm bathochromic shift in contrast to that of poly( p -phenylene)(PPP). The energy gap( E g) of * transition is about 3.3eV which be calculated by absorption edge and is about 0.30.6eV larger thann that of PPP.The peak of photoluminescence and electroluminescence is located at 405nm.The thermal properties have been studied by TG and DSC. |
