Abstract

A supramolecular host system composed of a 2D layered structure was developed by combining 1,2-diphenylethylenediamine and N-phenyliminodiacetic acid. This 2D layered structure was formed by a hydrogen- and ionic-bonded network between 2(1)-helical columns.

Abstract

In a two-component columnar host system composed of racemic (rac)-1,2-diphenylethylenediamine and rac-1,1'-binaphthyl-2,2'-dicarboxylic acid, a cavity tuning mechanism resulted from changes in the structure of the columns using a specific combination of the following four molecules: (1R,2R)-1, (1S,2S)-1, (R)-2, and (S)-2.

Abstract

A charge-transfer (CT) complex, composed of 10,10'-dihydroxy-9,9'-biphenanthryl as the electron donor and 1,1'-dimethyl-4,4'-bipyridinium dichloride as the electron acceptor, is formed only by the inclusion of guest molecules. The color of this inclusion CT complex is sensitive to the component guest molecules.

Abstract

A solid-state fluorescence sensing system was created by using a chiral supramolecular organic fluorophore having a channel-like cavity composed of (1R,2S)-2-amino-1,2-diphenylethanol as a chiral molecule and 2-anthracenecarboxylic acid as a fluorescence molecule.

Abstract

[reaction: see text] Charge-transfer (CT) complexes composed of 1,1'-bi-2-naphthol derivatives as an electron donor and p-benzoquinone as an acceptor serve as an excellent host system for visual molecular recognition. This is because they form inclusion crystals with guest aromatic compounds which display remarkably different colors depending on the structure of the component molecules and on the method of crystallization (i.e., solution crystallization or solid cogrinding of component crystals).
