Ionic Self-Assembled Derivative of Tetraphenylethylene: Synthesis, Enhanced Solid-State Emission, Liquid-Crystalline Structure, and Cu Detection Ability.

A novel tetraphenylethylene complex composed of 4',4'',4''',4''''-(ethene-1,1,2,2-tetrayl)tetrabiphenyl-4-carboxylic acid (H ETTC) and dimethyldioctadecylammonium bromide (DOAB) with enhanced solid-state emission is designed and synthesized through an ionic self-assembly (ISA) strategy. The aggregation-induced emission property, phase behavior, and supramolecular structure of the complex are characterized by a combination of experimental measurements. The experimental results reveal that the ISA complex can self-assemble into an ordered helical supramolecular structure with enhanced luminescent properties, although the ETTC cores possess extensive conjugation and high rigidity.

Thermoplastic High Strain Multishape Memory Polymer: Side-Chain Polynorbornene with Columnar Liquid Crystalline Phase.

A thermoplastic high strain multishape memory polymer can be fabricated using a hemiphasmid side-chain polynorbornene (P1) with hexagonal columnar liquid crystalline (Φ ) phase. Without any chemical crosslinks, P1 can memorize multiple temporary shapes with high strain and exhibit excellent shape fixity and shape recovery. As the building blocks of Φ , the multichain columns in P1 act as robust physical crosslinks.

[Clinical observation on isolated electroacupuncture for treatment of peripheral facial paralysis].

Objective: To study on therapeutic effect of isolated electroacupuncture on peripheral facial paralysis.

Methods: One hundred cases were randomly divided into an observation group of 60 cases and a control group of 40 cases. The observation group were treated by isolated electroacupuncture and the control group by normal electroacupuncture.
