Confined Oxidative Polymerization of Preorganized Aniline Within Cyclodextrin-Based Bimolecular Tube Nanochannels for the Synthesis of Bispolypseudorotaxanes
The well-defined nanoconfined spaces of cyclodextrin-based bimolecular tubes (CBBTs) make them excellent nanocontainers for directing molecular assembly and polymerization. In this study, we designed and synthesized a novel CBBT with two regular nanochannels. Employed to pre-assemble aniline monomers via host–guest interactions, the CBBT further drove the oxidative polymerization of aniline, thereby forming a polyaniline (PANI)/CBBT bispolypseudorotaxane with specific chain lengths. The structure and morphology of the as-prepared PANI-based bispolypseudorotaxane were characterized using spectroscopic and electron microscopic techniques. The structural features and the host–guest interactions involved were further investigated, demonstrating the potential of this CBBT system as a nanoconfined reaction platform for constructing structurally ordered conjugated polymer materials.
Herein, we report the synthesis of pyrene-embedded carbon nanohoops (3PyCPP) via a triangular gold complex-templated assembly strategy, in which three pyrene units are strategically linked at their 1,6-positions. This synthetic approach yields four crystal structures, and only the enantiomeric conformers [(15,6)AAA3PyC...

Functionalized p-conjugated polymers have emerged as promising electrochromic materials due to their well-defined molecular structures, facile synthesis, and ability to form smooth and homogeneous thin films. Furthermore, surface cross-linking enhances the mechanical and environmental stability of these films while imp...

Structural assembly of nanomaterials imparts new and enhanced properties to individual components. The “Sol-gel” approach has been a traditional technique to connect diverse types of materials. Here, 3-mercaptopropyl (trimethoxysilane) (MPTS), a dual-functional ligand, has been employed to assemble one of the popular m...

The programmed construction of nanotubular architectures through self-assembly remains a major challenge in supramolecular chemistry, especially when targeting pores with dimensions within the molecular scale (1–5 nm) in aqueous media. This work introduces a strategy that integrates covalent design with ionic hydrogen...
