	Abstract:The ortho-chelated iron(II) complexes [FeCl(PMe3)3{(C6H3Cl-ortho)CH=N-R}] (R = Me, Ph) (3, 4) and [FeCl(PMe3)3{(C6H4-CH=N-R}] (R = Ph, n-Bu) (7 ，8) were prepared through oxidative addition of the C-Cl bond of ortho-chlorinated imine using iron(0) complexes, [Fe(PMe3)4]. The reaction of 3, 4 and 8 with CO delivered the carbonyl Fe(II) complexes 9 - 11. A one-pot reaction of [FeMe2(PMe3)4] with (C6H3Cl2-2,6)CH=N(C6H5) at CO atmosphere resulted in carbonyl Fe(II) complexes, [FeMe(CO)(PMe3)2((C6H3Cl-ortho)CH=N-Ph)] (12). The crystal and molecular structures of complexes 3, 4, 7, 8, 9, and 12 were determined by X-ray diffraction.

	2. An efficient and recyclable water-soluble palladacycle precatalyst for Suzuki coupling in aqueous solvents under aerial conditions

	Abstract:Several water-soluble palladacycles were prepared as air-stable solid from the imine ligands bearing sulfonic group on N-phenyl group. The palladacycles with a six-membered ring gave high catalytic efficiency for the Suzuki coupling of aryl bromides and an activated aryl chlorides in aqueous solvent under mild conditions. The palladacycle 1 can be used for five reaction cycles in high conversions for the Suzuki coupling of 4-bromoanisole at reflux temperature in neat water. TEM analysis suggests a catalytic mechanism of recyclable palladium nanoparticles for the Suzuki coupling. The surfactant-protected palladium nanoparticles gave lower yields of the coupling product than those generated from palladacycle in situ due to the capping of free sites of metallic species.

	Abstract:Successful hydrodechlorinations of aryl chlorides were carried out in the presence of palladium catalyst supported by dppf and sodium formate in DMA (N, N-dimethylacetamide). A series of substituted aryl chlorides as substrates were studied to investigate the influence of electronic effects on the reaction. A proposed mechanism of hydrodechlorination via decarboxylation and hydrogen migration was discussed with the supported of in situ IR data.

	Abstract:In this study, a new kind of calcium-selective fluorescent probe Fluo-3ClMM-OH was synthesized. The structure of reaction products were characterized by IR and 1H NMR spectra. The molecular weights were measured on MALDI-TOF MS. Methylation of the crude product provided an effective method for separation. The fluorescence emission wavelength maxima of Fluo-3ClMM-OH were also researched.

	6. Multisensing Anion Recognition with thioure based Receptor functionalized with tetrathiafulvalene Unit

	Abstract:A series thiourea/urea-based anion receptors functionalized with tetrathiafulvalene (1-4) were prepared. Among them, 4 displays the high sensitive multisensing for acetate anion over various anions in acetonitrile with dramatic changes in UV-vis spectra , cyclic voltammogram and 1H NMR spectra. Conformation change induced by anion complexing of 4 caused the improvement of ICT channel to enhance the charge transfer not noly from thiourea moiety but also from TTF unit to electron-defect benzene ring. TTF unit plays a synergic charge transfer role for trifluoromethyl group in the ICT process. DFT calculation supported the hypothesis of conformational change and ICT channel improvement.

	Abstract:hree novel tetrathiafluvalene-annulated metalloporphyrazine dyes with electron- withdrawing pentoxycarbonyl groups at periphery were synthesized via a cyclotetramerization of dipentyl 6,7-dicyanotetrathiafulvalen-2,3-dicarboxylate in the presence of corresponding metal salts (Zn(OAc)2•2H2O, Cu(OAc)2•2H2O, and NiCl2) in pentanol and the structures were fully characterized by 1H-NMR, FT-IR, UV-vis, MULDI-TOF mass spectra and elemental analysis. The newly synthesized macrocyclic dyes are sufficiently air-stable for the purification process, where the electron-withdrawing substituents reduced the propensity to form the radical cation of tetrathiafulvalene groups . Their solution electrochemical data show one reductive and three oxidative processes within -2000 mV to +2200 mV potential window. Four couples can be assigned to Pz-2/Pz-3 (I), TTF+•/TTF (II), TTF+2/ TTF+• (III), and Pz-1/Pz-2 (IV).

	Abstract:A calix[4]arene derivative (2) possessing bis(indolyl) groups has been synthesized in satisfied yield, and further its response to metal ions was investigated by the methods of UV-vis spectrometry. The results obtained show that 2 displays high sensitivity to Hg2+. The addition of Hg2+ made the absorption spectrum of 2 appear a new band around ca 500 nm, and caused obvious color change of solution from colorless to orange-yellow. Hence, the detection of Hg2+ can be easily found by naked eyes. Calixarene 2 may be used for application as Hg2+-selective chemosensor, even in aqueous solution.

	10. Binding Behaviors of Tryptophan-containing Oligopeptides by b-Cyclodextrin-Coated Gold Nanoparticles

	Abstract:Three b-cyclodextrin derivatives were respectively chemisorbed onto the gold nanoparticles to give the b-cyclodextrin-coated gold nanoparticles, which were sufficiently characterized by 1H NMR, FT-IR, elemental analyses, ICP-AES and transmission electron microscopy (TEM). Spectrophotometric studies showed that these coated gold nanoparticles could efficiently enhance the fluorescence of tryptophan and tryptophan-containing oligopeptides through the selective binding of b-cyclodextrin cavities with the tryptophan groups attached on the surface of gold nuclei. Fluorescence titrations give the apparent association constants for the binding of coated gold nanoparticles with tryptophan and tryptophan-containing oligopeptides. The molecular binding ability and selectivity are discussed from the viewpoint of induced-fit effect between host and guest.
