[Ru(bpy)2dppz]2+ electrochemiluminescence (ECL) was studied, and it was used to investigate DNA interaction and develop a label-free ATP aptasensor for the first time. ECL of [Ru(bpy)2dppz]2+ is negligible in aqueous solution, and increases approximately 1000 times when [Ru(bpy)2dppz]2+ intercalates into the nucleic acid structure. The ECL switch behavior… (More)
Room-temperature ionic liquids (RTILs) are liquids at room temperature and represent a new class of nonaqueous but polar solvents with high ionic conductivity. The conductivity property of carbon nanotubes/RTILs and carbon microbeads/RTILs composite materials has been studied using ac impedance technology. Enzyme coated by RTILs-modified gold and glassy… (More)
A novel class of chiral coordination polymer organogels, with multi-stimuli responsive properties and suitable for use as catalysts in 1,3-dipolar Huisgen cycloaddition reaction, are reported.
ZIF-8 crystal coatings were prepared by direct growth on different flexible polyimide substrates including a thin membrane and electrospun nanofiber mat. In SEM pictures, the ZIF-8 crystals exhibit a rhombic dodecahedron morphology. Owing to the flexible polyimide substrate, the MOF-polymer film may be moderately bent or easily tailored when not destroyed.… (More)
A novel low density two-fold interpenetrated MOF-5 analogue with pcu topology, JUC-100, was designed and prepared successfully. It can be regarded as MOF-5 in which half of the Zn(4)O(CO(2))(6) units are replaced by organic 1,3,5-triphenylbenzene segments. JUC-100 exhibits H(2) uptake ability comparable to interpenetrated MOF-5, but relatively low initial… (More)
Two non-interpenetrated and isomorphous MOFs with nia topology, cationic JUC-101 and anionic JUC-102, are synthesized by connecting a trigonal prismatic metal cluster with an octahedral organic ligand. JUC-101 obtains a BET surface area of 3742 m(2) g(-1) and can absorb 4.18 wt% of H2 at 30 atm and 77 K, while JUC-102 can absorb cationic dye molecules and… (More)
A new fluorinated version of a cyclic β-aminoalcohol gelator derived from 1,2,3,4-tetrahydroisoquinoline is presented. The gelator is able to gel various nonprotic solvents through OH⋅⋅⋅N hydrogen bonds and additional CH⋅⋅⋅F interactions due to the introduction of fluorine. A bimolecular lamellar structure is formed in the gel phase, which partly preserves… (More)
An atropisomeric biaryl molecule with a given absolute configuration could present two opposite helical conformations through the rotation around C-C single bond. To the best of our knowledge, the biaryl system is the simplest helical inversion model apart from stereomutation between two enantiomers. Herein, we first report such true helical inversion… (More)
A homochiral MOF membrane was successfully and facilely synthesized using an in situ growth method, which had the advantages of cheap raw materials, simple operation and high thermal stability. A diol isomer mixture was used to test the separation efficiency of the membrane at different temperatures and pressures.
A heterochiral metallocycle was formed by self-discriminating assembly of racemic bisbipyridines and silver ions, and further self-organized into nanofibers immobilizing organic solvents in a distinct pattern from the enantiopure version reported by us previously.
