Two functional tetraphenylethylene derivatives modified by vinylpyridine and vinylnitrobenzene,respectively, were synthesized by Heck coupling reaction. Their optical behaviors were investigated. The results showed they had AIE activity in solution. The property in solid state displayed that both of them had reversible mechanochromism. Upon grinding, their fluorescence spectra showed around 13–40nm red-shift, and could return to the original state after solvent fuming. We believe that this work will be helpful for the design of stimuli-responsive materials in future.

Hepatitis B is a well-known risk factor for the development of fiver cancer and is closely associated with patient morbidity and mortality. Viral mutants and variants have the potential to evade immune response and prolong infection, and thus it is crucial to develop a methodology for the rapid identification of multi-strain hepatitis infections in patients. Here we describe a method based on selective region amplification of viral genome and deep sequencing, which may be used for rapid identification of multi-strain hepatitis B virus （HBV） infection in patients. The method works even with significantly low amounts of patients＇ serum samples, where the wet-lab procedures take about 1.5 days, followed by a quick bioinformatic analysis to reveal the final results. Our method can potentially be applied to the rapid and reliable identification of multi-strain HBV infection and help improve treatment regiments.

Two star-shaped molecules with benzene core and three naphthalene diimide （NDI） side arms were facilely prepared by two-step imidization reaction from the 1,4,5,8-naphthalenetetracarboxylic dianhydride. Two com- pounds showed the similar UV-Vis absorption band as well as NDI. It was found that they displayed bathochromic shift of their UV-Vis absorption and emission spectra in film compared with that in solution, ascribing to the aggregation between molecules in the solid state. Reversible reduction process was observed by cyclic voltammetry and low lying LUMO energy levels （-3.83 eV for la, -3.87 eV for lb） were deduced, which suggest that these two compounds possessed good electron-acceptor property and can be used as potential n-type materials.
