A design and synthesis of three unique triptycene based polymers containing azo linkages in the side chain of polymer backbone is being reported herein for the first time. These triptycene based azo-polymers (TBAPs) have high solubility in common organic solvents due to the presence of pendent alkyl chains as well as triptycene motifs. TBAPs are well characterized by GPC, TGA, ¹H NMR, FTIR, PXRD, FESEM, UV and fluorescence spectroscopy. Polymers with azo-linkages are generally non-fluorescent. However, TBAPs are fluorescent in nature which makes them unique. It was observed that TBAP3 having the longest pendent alkyl chain is most fluorescent when compared with TBAP1 and TBAP2 (which have smaller pendent alkyl chains). Furthermore, TBAPs have been applied for the detection of trace quantities of PA in THF. The binding constants of TBAPs with PA are in the order of 10⁵ M⁻¹ and the PA can be detected even in nanomolar concentrations. It was observed that TBAP1 having the smallest pendent alkyl chain has the highest binding affinity for PA relative to TBAP2 and TBAP3 (having longer pendent alkyl chains). Further, the effect of the chain length on the supramolecular assembly of these polymers was observed using FESEM. The size of domains present in polymer films was found to increase with increasing chain length of alkyl group.

本文首次报道了在聚合物主链的侧链中包含偶氮键的三种独特的基于三茂铁的聚合物的设计和合成。这些三萜烯基偶氮聚合物（TBAP）由于存在侧链烷基和三萜烯基序而在常见的有机溶剂中具有较高的溶解度。TBAP通过GPC，TGA，¹ H NMR，FTIR，PXRD，FESEM，UV和荧光光谱法得到了很好的表征。具有偶氮键的聚合物通常是非荧光的。但是，TBAP本质上是荧光的，这使其具有独特性。据观察，TBAP3具有最长的烷基侧链的情况相比是最荧光TBAP1和TBAP2（具有较小的侧链烷基）。此外，TBAP已用于检测THF中的痕量PA。TBAP与PA的结合常数约为10 ⁵  M ^-1，即使在纳摩尔浓度下也可以检测到PA。据观察，TBAP1具有最小的烷基侧链具有用于相对于PA最高结合亲和力TBAP2和TBAP3（具有更长的悬垂烷基链）。此外，使用FESEM观察了链长对这些聚合物的超分子组装的影响。发现存在于聚合物膜中的畴的尺寸随烷基链长的增加而增加。
