Smart protein-mimetic materials have received increasing interest for many applications. Here, we reported a facile and efficient approach to prepare a class of dual-responsive copoly(l-glutamate)s by ring-opening polymerization (ROP) and post-modification strategy. Both the oligo(ethylene glycol) (OEG) and glutamic acid residues were incorporated to offer thermal- and pH-responsive property simultaneously...
Three s-triazine-based functional monomers with thermo-polymerizable propargyl-ether units were synthesized by a facile procedure. These monomers can be thermally cured to form the crosslinked networks, which showed 5-wt% loss temperature of up to 400 °C and the char yields of more than 50% at 1000 °C. Moreover, the crosslinked networks exhibited the coefficients of thermal expansion (CTE) of below...
A novel benzocyclobutene-functionalized poly(m-phenylene) was synthesized. This polymer showed good solubility and film-forming ability. When being heated at high temperature, the polymer film converted to an insoluble cross-linked network structure and did not show any cracks. Thermogravimetric analysis of the polymer film exhibited a weight loss of 5% at 547 °C and a char yield of 71% at 1000 °C...
A novel biodegradable Y-shaped copolymer, poly(l-lactide) 2 -b-poly(γ-benzyl-l-glutamic acid) (PLLA 2 -b-PBLG), was synthesized by the ring-opening polymerization (ROP) of N-carboxyanhydride of γ-benzyl-l-glutamate (BLG–NCA) with centrally amino-functionalized poly(l-lactide), PLLA 2 -NH 2 , as a macroinitiator in a convenient way. The Y-shaped copolymer and its precursors...
A series of new π-conjugated poly(anthracene-alt-fluorene)s with X-shaped repeating units were synthesized. The polymers were easily soluble in common organic solvents and had good film-forming abilities. They showed high absolute PL quantum yields in the solid state. The electroluminescent devices based on the three X-shaped polymers with a configuration of ITO/PEDOT:PSS/polymer/LiF/Ca/Al emitted...
A novel biodegradable triblock copolymer poly(ethylene glycol)-b-poly(l-lactide)-b-poly(l-lysine) (PEG–PLA–PLL) was synthesized by acidolysis of poly(ethylene glycol)-b-poly(l-lactide)-b-poly(ɛ-benzyloxycarbonyl-l-lysine) (PEG–PLA–PZLL) obtained by the ring-opening polymerization (ROP) of ɛ-benzyloxycarbonyl-l-lysine N-carboxyanhydride (ZLys NCA) with amino-terminated PEG–PLA–NH 2 as a macroinitiator,...
