A simple method for the hydrosilylation of olefins by using air-stable cobalt catalysts is developed. The catalyst system is composed of simple, cheap, and readily available cobalt(II) salts and well-defined terpyridine derivatives as cocatalysts or ligands, and the hydrosilylation processes can be processed smoothly under mild conditions without either Grignard reagents or NaHBEt3 as activator.

A novel carbazole derivative (L) functionalized by terpyridine was designed and synthesized. Its structure was fully characterized by FT-IR, HR-MS, 1H NMR spectra. L formed J-aggregates and possessed aggregation-induced emission enhancement property in aqueous environment. In addition, compound L showed specific response to Fe2+ in UV-vis spectra at 557 nm in EtOH-H2O mixed solvent, owing to metal-to-ligand-charge-transfer (MLCT). The emission quenched much more sharply than other metal ions when adding Fe2+. The interaction between compound L and Fe2+ was analyzed by UV-vis and fluorescence spectrum titration. The limit of detection was calculated to be 1.63 μM. The stoichiometric of L and Fe2+ was 2:1 confirmed by Job's plots. Competition experiment indicated that other metal ions caused little interference. In this way, L could be a fluorescent and "naked eyes" probe for Fe2+ detection. This dual mode Fe2+ sensor can be considered to have potential value in practical applications.

Two gluconic acid derivatives C3 and C6 bearing a terpyridyl moiety were designed and synthesized. Thanks to the hydrophilic interaction from glucosyl moiety, C3 and C6 can dissolve in polar solvents and gel aromatic solvents with a critical gel concentration of weight 1.5%. The solution consisting of organic ligand C3 as sensitizer and Ln(III) ions as emitters can realize white light emission with thermo- and chemical stimuli-response properties in luminescence spectra. Further, the self-assemblies of C3 and C6 were examined by the combination of the theoretical calculations via hybrid density functional theory (DFT) with 1H nuclear magnetic resonance (1HNMR) and powder X-ray diffraction (PXRD) analysis. The study actually provides a reliable method for the formation of potential functional smart materials.

Based on gluconic acid acetal and terpyridyl groups, we have prepared two new supramolecular gelators C3S and C6S with the critical gelation concentrations of 0.1% in aryl halides and the ability of gelling in DMF/DMSO + H2O at room temperature. The excellent self-healing properties of the gels were studied using rheological experiments. Based on the 1H NMR, IR spectrum and PXRD, the self-assembly pattern of C6S was proposed through theoretical calculation. After coordinating with Ln(III) metal ions, the multicolor luminescent metallogel C6S-Eu/Tb was investigated. The luminescence properties of the gels were characterized by fluorescence spectroscopy and fluorescence lifetime measurements, confirming the energy transfer between the organic compounds and Ln(III) metal ions.
