An intrinsic white-light-emitting semi-aliphatic hyperbranched polyimide with epoxide terminal groups (EHBPI) has been reported for the first time. The UV/vis absorption spectra and density functional theory calculations showed that the lowest electr

N,N,N′,N′-tetraglycidyl-4,4′-diamino-diphenylmethane (TGDDM) is the most widely used epoxy matrix in aerospace/aircraft industries, however its cured product suffers from cyclization side reactions, inadequate toughness and water resistance, an

It has been experimentally shown that epoxide-terminated hyperbranched polyether sulphone (EHBPES) can significantly improve the mechanical properties of traditional diglycidyl ether of bisphenol A/triethylenetetramine (DGEBA/TETA) systems, but the o

The design and synthesis of high performance epoxy anti-corrosion coatings are very desirable; however, they still remain a big challenge until today. In this paper, epoxide-terminated hyperbranched polyether (EHBPE) was incorporated into epoxy coati

A series of barbituric acid-based heterocyclic dyes were prepared and fully characterized by ESI-MS, NMR and UV–Vis absorption spectroscopy. UV–Vis spectral comparisons reveal that in contrast to mono-heterocyclic dyes the absorption maxima of ba

A high performance, low cost, and environmentally friendly epoxy is demonstrated for the first time by copolymerizing a small amount of epoxide-terminated hyperbranched polyether (EHBPE) with DGEBA. Unlike typical epoxy systems, which involve large a

The strong fluorescence, in both the solution and the bulk state, of a chromophore-free aliphatic hyperbranched polyether which does not contain N and P atoms was reported for the first time. Effects of concentration and solvent solubility were measu

A strategy to synthesize multilayer hyperbranched–hyperbranched macromolecules with an invariant degree of branching (DB) and a controllable molecular weight (MW) is realized by taking advantages of competing reactions. The invariant DB and tunable

Hyperbranched polyethers with different structures and molecular weights (MW) were synthesized using the A2+B3 approach by varying monomer ratio, A2 structure, and reaction time. Effects of backbone structure and MW on melt rheological behaviors were
