Novel pyrenyl‐moieties‐decorated hyperbranched polyglycidol (pHBP) is synthesized and utilized for the functionalization of carbon nanotubes (CNTs) via a non‐covalent (non‐destructive) process. Mediated by a pHBP layer on the CNT sidewall, Au, Ag and Pt nanoparticles and uniform SiO 2 , GeO 2 and TiO 2 coatings are generated in situ and deposited onto the as‐prepared CNT/pHBP hybrids, forming versatile homogeneous CNT‐based nanohybrid sols. The coverage of metal nanoparticles and oxide coatings is controllable simply by changing the employed amount of precursors. This easy synthetic strategy provides a general and convenient route to efficiently assemble a wide range of metal nanoparticles and inorganic oxide components on the sidewalls of CNTs, and enables the construction of heterogeneous nanostructures with novel functionalities. As a means of demonstrating the versatility of the fabricated hybrid materials, the catalytic function of CNT/pHBP/Pt hybrids towards the reduction of 4‐nitrophenol and the incorporation of dye molecules into the CNT/pHBP/SiO 2 matrix resulting in fluorescent nanofibers are investigated.
