the further construction of polypseudorotaxane was not conducted. The
Sonogashira polycondensation was also applied by Cao and coworkers to synthesize another pillar[5]arene incorporated conjugated polymer (P1) with the
number-average molecular weight (Mn) about 13 kDa. After binding the homoditopic guest, the polypseudorotaxane was successfully constructed (Fig. 11)
[25].
Besides the mentioned polymer, the side-chain supramolecular polymers have
also been fabricated. Wang and coworkers successfully synthesized the side-chain
functionalized polyphenylethynylene, whose linker was flexible alkyl chain. After

polypseudorotaxane reported by Ogoshi and coworkers. (Reprinted with permission from Ref. [23].
