Poly(p-phenyleneethynylene)s (PPEs), made up of rigid backbone with alternating arylenes and ethynylenes, exhibit high conductivity and chemical stability, and thus they have huge potentials for various applications, including chemosensors, electronic and photonic devices. According to recent reports, PPEs effectively bind to single-walled carbon nanotubes (SWNTs) through π-π interactions, revealing a well-defined morphology of SWNT-semiconducting polymer composites. In this presentation, we present the synthesis of two sidechain-tailored PPEs, poly(ethylene oxide)-grafted PPEs and cyclodextrin-encapsulated PPEs. We also prepare the supramolecular composites of SWNTs with these conjugated polymers, both of which are found to interact with the nanotube sidewalls in a parallel mode and play a role in assembling a superstructure of SWNTs. Various characterization techniques successfully characterize their spectral and morphological properties. |
