Regulating the conductivity of conducting polymers has spurred increasing studies, aiming at meeting different demands in various fields, including chemosensors, photovoltaic cells, and so on. Herein, linear pillar[5]arene-containing conjugated polymers were designed and synthesized via metathesis cyclopolymerization of pillar[5]arene-functionalized 1,6-heptadiyne. Upon addition of an ionic guest, such polymers could form inclusion complexes, of which the glass transition temperature decreased dramatically. With the aid of ionic guest and host–guest complexations between the pendant pillararenes and guest, these supramolecular materials exhibited tunable conductivity from 10^–12 to 10^–3 S·cm^–1 at 30 °C. In addition, compared with the polymers without pendant pillar[5]arenes, such polymers showed better compatibility with the ionic guest, which could prevent the leakage of the latter one and was good for the conductivity of the material.

基于主客体络合的具有可调电导率的含柱芳烃聚合物

调节导电聚合物的电导率引发了越来越多的研究，旨在满足各个领域的不同需求，包括化学传感器、光伏电池等。在此，通过对柱[5]芳烃官能化的1,6-庚二炔进行复分解环聚合，设计并合成了含线性柱[5]芳烃的共轭聚合物。在添加离子客体后，此类聚合物可形成包合络合物，其玻璃化转变温度显着降低。借助侧链柱芳烃和客体之间的离子客体和主客体络合，这些超分子材料表现出从 10 ^–12到 10 ^–3 S·cm ^{–1的可调电导率}在 30 °C。此外，与没有侧柱[5]芳烃的聚合物相比，该聚合物与离子客体的相容性更好，可以防止后者的泄漏，有利于材料的导电性。
