- A self-assembling receptor for dicarboxylic acids
-
In this paper we describe a simple binding subunit that self-assembles in the presence of metal ions to form a receptor for dicarboxylic acids. The resultant binding site is chiral and strong complexation to dicarboxylic acids in CDCl3 can be d

- Intriguing C-H?Cu interactions in bis-(phenanthroline)Cu(i) redox mediators for dye-sensitized solar cells
-
We have synthesized and characterized a series of bis-(phenanthroline)Cu(i) complexes of interest as redox mediators for dye-sensitized solar cells. This study led to the discovery of intriguing anagostic interactions between the hydrogen atom and the copper center as evidenced by X-ray diffraction studies on a single crystal. Remarkably, an anagostic interaction was found between a H atom of a methyl group and a copper site.

A compound is represented by a formula (1) below. In the formula (1), X 1 to X 8 each independently represent a carbon atom to be bonded to a group represented by a formula (20) below, CR X or a nitrogen atom. At least one of X 1 to X 8 is a carbon atom to be bonded to the group represented by the formula (2). R X is independently a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 30 carbon atoms, and the like.

- A rapid synthesis of asymmetric alkyl- and aryl-2,9-disubstitued 1,10-phenanthrolines

The finding that alkyl- and aryllithium reagents add almost instantly to the N-C2/C9 bond of 1,10-phenanthrolines led us to the development of a reaction scheme where the C2 and C9 positions of 1,10-phenanthroline can be functionalized by two different al

- Introduction of benzo[h]quinoline and 1,10-phenanthroline subunits by friedl?nder methodology
-
An improved preparation of 8-amino-7-quinolinecarbaldehyde has been developed. The methyl group of 7-methyl-8-nitroquinoline may be oxidized to an aldehyde by treatment first with dimethylformamide dimethyl acetal followed by sodium periodate. Reduction with iron provides the amino aldehyde. An analogous sequence affords 1-amino-2-naphthalenecarbaldehyde. Friedl?nder condensation of the quinoline derivative with a series of acetylaromatics provides the corresponding 2-aryl-1,10-phenanthrolines. Condensation of either amino aldehyde with 1,3-diacetylbenzene or 2,6-diacetylpyridine provides the expected Friedl?nder product. Similar chemistry is described for reactions of the amino aldehydes with 1,4-diacetylbenzene, 4,4′-diacetylbiphenyl, 1,5-diacetylanthracene, 1,2,3,4,5,6,7,8-octahydroacridine-1,8-dione, and tetracyclo-[6.3.0.0.4,1105,9]undecane-2,7-dione (TCU-2,7-dione).
