Functional Materials and Biomaterials
This review article summarizes the synthetic efforts in constructing functional
hyperbranched macromolecules from acetylenic triple-bond building blocks. Polymerization
reactions including polycoupling, polyaddition and polycyclotrimerization have been
developed for the synthesis of new hyperbranched polymers such as polyynes, polyenes,
polyarylenes and polytriazoles with novel topological structures and electronic conjugations.
Polymers with high molecular weights (up to > 1×106) have been obtained in high
yields (up to 100%). Whilst their linear counterparts are often intractable, the hyperbranched
conjugated polymers are completely soluble in common organic solvents and
are hence readily processable by macroscopic techniques. The hyperbranched polymers
exhibit an array of functional properties including strong light emission, stable optical nonlinearity and high photorefractivity.
The polymers can generate fluorescent images, assemble into supramolecular patterns, and form well-aligned nanotubes. The polyynes
can be post-functionalized through metal complexation, whose refractive indexes can be
manipulated to a great extent by photoirradiation. The hyperbranched polymer complexes
can serve as precursors to soft ferromagnetic ceramics and as catalysts for carbon
nanotube fabrications.
