Abstract In this paper, nitrogen‐coordinated boroxines are exploited for the fabrication of self‐healing and recyclable polymer composites with enhanced mechanical properties. The 3D networks cross‐linked first synthesized through trimerization ortho ‐aminomethyl‐phenylboronic acid groups at terminals poly(propylene glycol) (PPG) chains, subsequently, mechanically robust fabricated by utilizing complexation boroxine‐containing PPG (N‐boroxine‐PPG) poly(acrylic acid) (PAA) hydrogen‐bonding...
Abstract Supramolecular polymer networks (SPNs), crosslinked by noncovalent bonds, have emerged as reorganizable and recyclable polymeric materials with unique functionality. However, poor stability is an imperative challenge faced SPNs, because SPNs are susceptible to heat, water, and/or solvents due the dynamic reversible nature of bonds. Herein, design a cooperative network (NCoN) simultaneously stabilize reinforce reported, resulting in ultrastable, superrobust, SPN. The NCoN constructed...
Strong supramolecular interactions, which induced tight packing and rigid molecules in crystals of cyano substituent oligo(para-phenylene vinylene) (CN-DPDSB), are the key factor for high luminescence efficiency its crystals; opposite to isolated solution have very low efficiency.
A series of highly efficient deep red to near-infrared (NIR) emissive organic crystals 1-3 based on the structurally simple 2'-hydroxychalcone derivatives were synthesized through a one-step condensation reaction. Crystal 1 displays highest quantum yield (Φf) 0.32 among reported single with an emission maximum (λem) over 710 nm. Comparison between bright and nearly nonluminous compounds 4-7 clearly gives evidence that subtle structure modification can arouse great property changes, which is...
Human conversations naturally evolve around related concepts and hop to distant concepts. This paper presents a new conversation generation model, ConceptFlow, which leverages commonsense knowledge graphs explicitly model flows. By grounding the concept space, ConceptFlow represents potential flow as traverses in space along relations. The traverse is guided by graph attentions graph, moving towards more meaningful directions order generate semantic informative responses. Experiments on...

Two novel four-coordinate boron-containing emitters 1 and 2 with deep-blue emissions were synthesized by refluxing a 2-(2-hydroxyphenyl)benzimidazole ligand triphenylborane or bromodibenzoborole. The boron chelation produced new π-conjugated skeleton, which rendered the materials intense fluorescence, good thermal stability, high carrier mobility. Both compounds displayed in solutions very fluorescence quantum yields (over 0.70). More importantly, samples showed identical solution solid...
