Abstract:With triphenylamine and fluorenone as raw materials, three novel triphenylamine derivatives: (4-fluorenylidene hydrazo methylenephenyl)diphenylamine, bis-(4-fluorenylidene hydrazo methylenephenyl)phenylamine and tris-(4-fluorenylidene hydrazo methylenephenyl)amine（a~c） were synthesized via Nucleophilic Addition. The structures of the three target compounds were characterized by means of FTIR, 1HNMR and elemental analysis. Their UV-Vis spectra, fluorescence spectra, electrochemical behavior and thermal stability were studied respectively. The results show that the thin films of three compounds（a~c） emit red fluorescence. They all obviously have the performance of Aggregation-Induced Emission (AIE). Their ionization potential energy levels (5.62~ 5.65 eV) are matched with work function (4.8 eV) of positive electrode（ITO）, so the barrier of hole transporting can be effectively reduced and in favor of hole-transport. The results of TG curves show that their thermal decomposition temperatures (Td) are 317，292 and 303 ℃ and they all have good thermal stability.

Abstract:Two mutagenesis strains named NY3-1 and NY3-2 were obtained through pseudomonas aeruginosa NY3 inducing with levofloxacin. By comparing the physical and chemical properties of rhamnolipids produced by them, some conclusions were reached as follows: Production, composition and structure characteristics of rhamnolipids produced by mutagenesis strains and wild strains were quite different. Compared with the wild strains，yield of rhamnolipids produced by NY3-1 was improved by 19.57%, while for NY3-2 the yield was decreased by 17.60%. the ratios of amounts of disaccharide and monosaccharide in rhamnolipids produced by NY3、NY3-1、NY3-2 strains were 0.969,0.677 and 1.316 respectively. The infra-red spectrums demonstrated that no C=C unsaturated bond was found in the rhamnolipids produced by NY3 strains, while those produced by NY3-1 and NY3-2 strains contained C=C bond. The results from electrospray ionization mass spectrometry (ESI-MS) analysis showed that all the rhannolipids produced by the three stains contained Rh-C10,while only that produced by two induced strains have high content of Rha-Rha-C10:1 which contain C=C unsaturated bond.

Abstract:The zeolite Y synthesized by in-situ crystallization technique was modified with phosphate. The crystalline structure and surface acidity of the modified zeolite Y(named zeolite PY) were characterized by using techniques such as X-ray diffraction ( XRD) , NH3 temperature programming desorption (NH3-TPD). The results showed that the introduction of phosphorus had no effect on crystal form of the zeolite PY, and the caused impact on relative crystallinity was obscure. Moreover, the space unit shrank, the cell parameter decreased, and the molar ratio of Si/Al increased. It was found that the modified PY catalyst could effectively adjust the total acid amount and acid strength of the catalysts. The introduction of phosphorus could also decrease the total acidity, weak acidity and strong acidity, but increased the moderately strong acidity. Further evaluation that carried on a small fixed fluidized bed showed that the modified PY catalyst exhibited excellent heavy oil cracking capability an d superior selectivity to desired products．

Abstract:In water-containing catalytic reactions, regarding of whether water is reagent, reaction medium or product, water has much influence on the activity and life of hydrophilic catalysts. Hydrophobic catalysts can well overcome the disadvantage of hydrophilic catalysts by avoiding the coverage of water on active components. In recent years, SDB (styrene-divinylbenzene copolymers) have got more and more attention in the field of catalyst preparation due to the distinct hydrophobicity of SDB. Advances of research and application of hydrophobic catalysts over SDB in nuclear industry and the production of saturated acid /ester and olefine acid /ester were reviewed in this paper. Based on the research, the room of research and application of the hydrophobic catalyst was prospected.
