STUDY AND APPLICATION OF A NOVEL CHEMILUMINESCENCE REACTION

The present paper reports a novel chemiluminescence,i.e,isopropylalcohol-C10~--H_2O_2 system.The chemiluminescence intensity is proportionalto the concentration of C10~- within certain range.Based on this fact,anew chemiluminescence method for the determination of micro amount of C10~-has been developed.The detection limit is 2.6 x 10~(-8)g/ml C10~- and thedynamic linear range is 2.6 x 10~(-8)g/ml to 2.3 x 10~(-5)g/ml C10~-.The methodhas good selectivlty and reproducibility.

SYNTHESIS AND CHARACTERIZATION OF A NOVEL REACTIVE OLIGOMERIC LADDERLIKE COPOLYMETHYL-AMINOPROPYL SILSESQUIOXANE

A novel ordered reactive oligomeric ladderlike copolymethyl-aminopropylsilsesquioxane (Me-AP-T), was successfully synthesized by an efficient hydrosilylation graft reaction of 1,1,1-trimethyl-N-2-propenyl-silanamine with a reactive oligomeric |adderlike copolymethyl-hydrosilsesquioxane (Me-H-T), which was prepared by “supramolecular chemistry-dictated stepwise coupling polymerization” process. FT-IR, ^1H- and ^29Si-NMR spectra show that hydrosilylation reaction proceeds completely. Moreover, ^1H-NMR spectra also indicate that both the molar ratios of ≡SiMe group to Si-H and ≡SiMe group to ≡SiPrNH2 are approximately 1:1 respectively based on the ratio of integrated resonance areas of the different groups. XRD analysis and ^29Si-NMR spectra are used for investigating the ladderlike structure of the polymers. A high Tg (128.38℃) of Me-AP-T shown in DSC measurement implies that the ordered reactive Me-AP-T macromolecules have much stiff chains.

A NOVEL MOLECULARLY IMPRINTED POLYMER： SYNTHESIS AND ADSORPTION BEHAVIOR OF GATIFLOXACIN

A kind of molecularly imprinted polymer （MIPs） with high selectivity was prepared using methacrylic acid （MAA） as functional monomer, ethylene glycol dimethacrylate （EDMA） as crosslinker and Gatifloxacin as template. The effect of various parameters such as volume of solvent, functional monomer dosage, crosslinker dosage and polymerization time were investigated. The selective binding experiment for substrates show that the affinity and selectivity for Gatifloxacin were higher than that for blank polymer. Scatchard analysis show that the MIPs recognized template with two kinds of binding sites. The dissociation constant Kd and maximum adsorption quantity Qmax of these two kinds of binding sites were calculated： Kd1 and Qmax1 of the binding sites with high affinity were 8.67×10^-4 mol/L and 28.19μmol/g, while Kd2 and Qmax2 of the binding sites with low affinity were 1.05×10^-3 mol/L and 33.20μmol/g respectively.     

SYNTHESIS AND CHARACTERIZATION OF A NOVEL BLUE LIGHT EMITTING ROD-COIL DIBLOCK OLIGOMER

Four new rod-coil diblock molecules, which had well-defined para-phenylene oligomers (PPP, from biphenyl toquinquephenyl) as rigid segments and poly(ethylene oxide) (PEO, M_w ca. 750) as flexible segments, were synhesized. Thechemical structure and the number of repeating unit in PEO coil and PPP rod were characterized by ~1H-NMR and MALDI-TOF mass spectromeny. The diblock oligomers showed good solubility in common organic solvents and aggregated in wateras characterized by a blue shift in UV-vis absorption spectra, a red shift in emission spectra, quenching of the fluorescenceand formation of the microfibrilla and fractal-like structures. The formation of different supramolecular structures meant thatthis effort might lead to commercial important highly organized functional materials.     

SYNTHESIS AND CRYSTAL STRUCTURE OF TWO NOVEL CARBENE AND CARBYNE COMPLEXES OF RHENIUM

The cationic carbyne complex of rhenium, [π-C_5H_5(CO)_2ReCC_6H_5] BBr_4(Ⅰ), in tetrahy-drofuran reacted with 1-lithiocarborane at low temperature, with addition of the carbo-ranyl anion to earbyne earbon and carbonyl carbon atoms to give two novel carbene andcarbyne complexes of rhenium, π-cyclopentadienyl (dicarbonyl) [(1-earboranyl) (phenyl)carbene] rhenium π-C_5H_5 (CO)_2ReC (C_2HB_(10)H_(10)) C_6H_5, (Ⅱ) and π-cyclopentadienyl-(carbonyl)(1-carboranylformacyl) (phenylcarbyne) rhenium π-C_5H_5 (CO) (COC_2HB_(10)H_(10)) ReCC_6H_5 (Ⅲ).This fact indicates that there are two electrophilic centers in the cationic carbyne complexⅠ. At room temperature the complex Ⅲ in solution transformed gradually into the complexⅡ. The complexes Ⅱ and Ⅲ were identified by elemental analyses, IR, ~1H NMR and massspectra, and finally by their single crystal X-ray structure determinations. The possiblereaction mechanism is suggested and discussed in this paper.
