based on this structure, the C1═C4···C1═C4 dihedral angle of the PDA chain found to be 140°. The C1═C4···C1═C4 dihedral angle in poly-THD, based on the known X-ray crystal structure of this polymer, is 167°. Thus, poly-6 appears to be a new structural type of PDAs; it is also a good model for the study of the relationship that exists between chain conformation and electronic structure.
已经制备了1,6-双(二苯基氨基)-2,4-己二炔(THD)的几种类似物,并评估了它们的热和光化学固态聚合反应性。该研究涉及的化合物是1,6-双(二苄氨基)-2,4-己二炔(1),1,6-双(二-对甲苯基氨基)-2,4-己二炔(2),1,6 -双(二五氟苯基氨基)-2,4-己二炔(3),1,6-双((N-五氟苯基)苯基氨基)-2,4-己二炔(4),1,12-双(二苯基氨基)-5,7 -十二碳二烯(5)和1,10-双(二苯基氨基)-4,6-癸二炔(6)。化合物6乙炔是唯一显示出可测量的聚合反应性的乙炔,并且这种行为已根据X射线晶体学结果进行了合理化。然而,二炔6是要比THD反应性较低,所以弱聚合单晶的制备6证明是可能的,并且“稀释”聚的光谱性质的研究6支链可行的。与聚THD不同,聚6在有机溶剂(如氯仿和THF)中的溶解度非常高,因此可以通过SEC测定该聚二乙炔(PDA)的分子量,M n = 150
