The diyne and diazide monomers, namely 1,4-bis(propargyloxy)
benzene (1), 1,2-bis[4-(azidohexyloxy)phenyl]-1,2-diphenylethene
(2a), and 1,2-bis[(4-azidomethyl)phenyl]-1,2-diphenylethene
(2b), were synthesized according to Scheme S1.10
The reactions proceeded smoothly, and the desired monomers
were obtained in good yields. The monomer structures were
confirmed by spectroscopic analyses (see Supporting Information
for detailed characterization data).10
We attempted to transform the monomers to their polymers
by 1,3-dipolar polycycloaddition. We have previously succeeded
in the catalyst-free polycycloaddition of bis(aroylacetylene)s
with diazides by simple heating.11 No high molecular weight
polymers, however, were obtained when 1 and 2 were refluxed
in THF for 110 h (Table 1, no. 1). This is due to the low
reactivity of diyne 1 because it contains no election-withdrawing
groups

二炔和二叠氮的单体,名称为1,4-bis(propargyloxy)benzene(1), 1,2-bis[4-(azidohexyloxy)phenyl]-1,2-diphenylethene(2a),和1,2-bis[4-(azidomethyl)phenyl]-1,2-diphenylethene(2b),是按照方案S1合成的。10反应进行平稳,所希望的单体产率良好。单体的结构由光谱分析确认(参见有关表征数据的支持资料)。10
我们试图将这些单体通过1,3-二极多环加成反应变换成它们的聚合物。我们以前用简单的加热方法已成功进行了bis(acroylacetylene)(二芳香烃酰基乙炔)与二叠氮的无催化剂多环加成反应。11 可是当1和2在THF中回流110h(表1,No.1)没有获得高分子量的聚合物。这是由于二炔1的低反应性引起的,因为它不含选择回抽基团(election-withdrawing group)。

二炔烃和二叠氮化物单分子,即是1,4-双苯(propargyloxy),
1,2苯基,1,2 -二苯基

该反应顺利进行,并且有效取得预期中的单体
从光谱分析中,单体结构得到证实,(请参照“支持信息”的具体特性化数据)
我们尝试通过1,3-双极聚乙烯环加成反应,将单体转化成聚合物
目前,我们已经通过简单加热,成功地进行无催化剂的聚乙烯环加成 双(芳酰基乙炔)和二叠氮化物的反应
11然而当(1)和(2)在四氢呋喃中被循环加热110个小时的时候,没有高分子聚合物产生,图1.1),这是因为二炔烃的活性低--------------
