An external heavy-atom effect in crystals was found to influence the reaction path of the photocyclization of cyclohexenones drastically, and that was successfully applied to control the cis-trans stereochemistry of the ...
An amphiphilic PAMAM dendron with aspartic acids on the periphery and an aliphatic chain at the focal point was synthesized. The dendrons initially self-assembled to nanospheres in aqueous solution and further translated...
A four-armed cage molecule was synthesized and its pH-controlled host-guest complexation with paraquat was studied. The influences of the location and composition of the arms were also investigated, guiding us to search ...
The reaction of 1,4-dimethoxybenzene and paraformaldehyde using AlBr(3) yields multiple-deprotected pillar[5]arenes. A1/B2 di-deprotected pillar[5]arene can be isolated by silica gel chromatography and washing procedures...
The half-sandwich tamoxifen derivative, Mn(CO)(3)(eta(5)-C(5)H(4)(Et)C=C(C(6)H(5))(2)), gives a radical cation which is charge-delocalized between the "cymantrenyl" and diphenylethene moieties and undergoes facile metal-...
Novel bisimide-fused acenes were synthesized via bismuth triflate mediated double-cyclization reaction of acid chlorides and isocyanates. Their optical and electrical properties revealed significantly smaller HOMO-LUMO g...
Anodic near-infrared electrochemiluminescence (ECL) from CdTe quantum dots was achieved at low potential on a glass carbon electrode and a strategy for greatly enhanced band-gap ECL was presented.
A novel core-shell molecularly imprinted polymer is firstly prepared by coating the MIP shell onto the surface of the metal-organic framework, which shows a homogeneous polymer film, cubic shape, thermal stability, and e...
Nickel(0) catalysts were used to produce substituted imidazoles in good to high yields using benzonitrile, p-substituted benzonitriles and 4-cyanopyridine as starting materials.
The ionic liquid, 1-ethyl-3-methylimidazolium tetracyanoborate, was employed to prepare a thiolate/disulfide ionic liquid electrolyte with low viscosity for organic dye-sensitized solar cells (DSCs). CoS was introduced a...
A cross-linked mutant endoglucanase II was prepared for enzymatic polymerization to cellulose. The cross-linked enzyme is composed of three mutant enzymes showing polymerization activity. A characteristic feature of the ...
UDP-2F-glucuronic acid was synthesized and analyzed as a mechanistic probe to investigate the ring contraction step catalyzed by UDP-D-apiose/UDP-D-xylose synthase (AXS).
A new efficient copper-catalyzed intramolecular amination reaction has been developed to readily synthesise a wide variety of multi-substituted 2H-indazole and 1H-pyrazole derivatives from easily accessible starting mate...
The chiral N-heterocyclic carbene bearing a proximal hydroxy group derived from L-pyroglutamic acid was found to be an efficient catalyst for the [3+2] annulation of enals and isatins to give the corresponding spirocycli...
A new chiral fluorescence receptor, designed to exploit aggregation-induced emission (AIE), exhibited not only an exceptionally high enantioselectivity but was also applicable to a wide range of chiral carboxylic acids. ...
Catalytic addition of silylacetylenes to alpha,beta-unsaturated ketones proceeded in the presence of a cobalt complex coordinated with a bisphosphine ligand to give high yields of beta-alkynylketones.
