The solid-state chiral optical properties of a 1-pyrenesulfonic acid/amine supramolecular organic fluorophore could be controlled by changing the type of the aromatic ring and not the chirality of the chiral amine component molecule in the solid state. © The Royal Society of Chemistry 2010.

A chiral anthracenecarboxylic acid/amine supramolecular organic fluorophore composed of a 2D layered network structure was developed by combining 1-amino-2-indanol and 2-anthracenecarboxylic acid molecules. This 2D, chiral fluorophore exhibits circularly polarized luminescence (CPL) without quenching the fluorescence in the solid state. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.

A tunable supramolecular thiophene host system with a chiral channel-like cavity is developed using (1R, 2S)-2-amino-1, 2-diphenylethanol. This thiophene host system possesses a chiral helical columnar structure. The chiral cavities are formed by the self-assembly of the helical column, and guest molecules are included by varying the helical structure and packing arrangement of this column. © 2010 Elsevier Ltd.

The achiral compound 2-(2-naphthylthio or 2-quinolinethio)-3- methylcyclohexen-1-one was found to crystallize in the chiral space group P212121. In one crystal, only one-handedness was found. In particular, although 2-(2-naphthylthio)-3-methylcyclohexen-1-one showed conformational polymorphism, both polymorphs were chiral crystals. © 2010 The Royal Society of Chemistry.

Although both enantiomers of two-substituted ether- and imide-bridged biphenyl compounds 1-3 are present in equal amounts at equilibrium in a solution, chiral crystals composed of one of the axially chiral enantiomers could be isolated by crystallization from the solution without any outside chiral source. © 2010 The Royal Society of Chemistry.

The achiral compound 2-methyl-3-(4-bromophenylthio)-1,4-naphthalenedione shows conformational and color polymorphism. The relationship between the conformational and color polymorphs (chirality and color) of 2-methyl-3-arylthio-1,4-naphthalenediones can change according to the type of arylthio group. © 2010 Elsevier B.V.

Journal of Molecular Structure | Year: 2010

A novel charge-transfer (CT) host system with a 1D column-like structure is developed. This 1D column-like structure is formed by the CT interactions between rac-6,6′-dibromo-1,1′-bi-2-naphthol (rac-1) and 1,1′-dimethyl-4,4′-bipyridinium dichloride (MVCl2). n-Alkyl alcohol molecules (guest molecules) can be introduced into the CT host system by tuning of the packing of its 1D CT column-like structure. The diffuse reflectance spectra (DRS) of this host system are sensitive to the type of guest molecules. © 2009 Elsevier B.V. All rights reserved.

A colored supramolecular charge-transfer (CT) host complex composed of racemic rac-[9,9′-biphenanthryl]-10,10′-diol, having a large and widely π-conjugated phenanthrene ring, as an electron donor and 2,5-dimethyl-1,4-benzoquinone as an electron acceptor has been developed. The molecular recognition properties (guest inclusion behavior and color) of the CT complex can be tuned by using electron donor molecules with different steric bulkiness and electron-donating properties. © 2010 The Chemical Society of Japan.

Supramolecular Chemistry | Year: 2010

A chiral charge-transfer (CT) complex was formed using achiral 9,10-bis(3,5-dihydroxyphenyl)anthracene (BDHA) as an electron donor and achiral 1,1′-dimethyl-4,4′-bipyridinium dichloride (MVCl2) as an electron acceptor. This chiral CT complex can include n-alkyl alcohol molecules as guests. On the other hand, when 1,1′-diphenyl-4,4′-bipyridinium dichloride and 1,1′-dibenzyl-4,4′-bipyridinium dichloride were used as electron acceptors, achiral CT complexes without guests were formed. It was found that the chiral crystallisation of the BDHA/MVCl2-CT host system was caused by steric and electric intermolecular interactions between host component molecules BDHA and MVCl2 during crystallisation. © 2010 Taylor & Francis.

By introducing carboxyl and n-alkyl groups into a biphenyl molecule, we can increase the photoluminescence quantum yields of biphenyl derivatives in the solid state. The solid-state fluorescence maxima (λem) of 4-biphenylcarboxylic acid derivatives change according to the n-alkyl group introduced. © 2010 Elsevier B.V. All rights reserved.
