Abstract: A novel Schiff complex DSHE-Zn prepared for alternating copolymerization of carbon dioxide and cyclohexene oxide (CHO). DSHE-Zn has been found to be a catalyst for coupling carbon dioxide and cyclohexene oxide to afford alternating copolymer, poly(cyclohexenylene carbonate) (PCHC). The structure of product was investigated by FT-IR and ¹H NMR

Abstract: A carbazole-based conjugated polymer bearing ruthenium complexes Pbpy(Ru)-Cz was synthesized aiming to obtain a material with dual functionalities of both light absorption and hole-transport for photovoltaic cells. Chemical structures of the monomers and polymers were confirmed by ¹H NMR, IR, and elemental analysis. Pbpy(Ru)-Cz showed good thermal stability and solubility. The absorption spectrum of Pbpy(Ru)-Cz showed a broader peak covering the wavelength range from 380 to 650 nm. Preliminary photovoltaic behavior was evaluated by fabricating photovoltaic cells. As measured under a 55 mW cm‾² compact white arc lamp, Voc, Jsc, FF and ηe of the device ITO/Pbpy(Ru)-Cz:PCBM/Al were 0.18 V, 0.019 mA cm‾², 0.22 and 1.40×10‾³%, pectively.

Abstract: Trusted computing technology is a basic and entirely solution for security problems of computer. In order to solve the security problem caused by dynamics and the uncertainty of the grid environment, the article has put forward a new trust model based on behavior and trusted computing to deal with the trusting relationship among the entities, and take different methods to deal with to the trusting relationship between inner-domain and intra-domain based on the concept of Identity right, and a method for measuring and evaluating the behavior trust are provided.
