Tanabe, Kana,Kato, Takashi
, p. 1864 - 1866 (2009)
Cyclobis(paraquat-p-phenylene)s complexed with anionic surfactants exhibit liquid-crystalline states and form pseudorotaxanes with tetrathiafulvalene in the condensed states.
Binding behaviors of p-sulfonatocalix[4]arene with gemini guests

A dozen of homoditopic cations, possessing different spacer lengths and rigidities, as well as sizes, shapes, and charges of terminal groups, were synthesized as candidate gemini guests for the complexation of p-sulfonatocalix[4]arenes (SC4A). The 12 gemini guests are divided into five species according to the different terminal groups: imidazolium (G1-G3), pyridinium (G4-G6), quinolinium (G7), viologen (G8-G11), and 1,4-diazabicyclo[2.2.2]octane (DBO, G12). Their binding structures and stoichiometries with SC4A were examined by NMR spectroscopy, which is helpful to construct diverse highly ordered assemblies. The obtained results show that the length of the linkers, as well as the charge numbers on the end groups have a pronounced effect on the binding stoichiometry, whereas the size and shape of the terminal groups have no significant influence. Furthermore, both the stability constants and thermodynamic parameters of SC4A with the terminal subunits were determined by the isothermal titration calorimetry experiments, which are valuable to understand the binding behavior, giving quantitatively deep insight.

Mechanical motion in the solid state and molecular recognition: Reversible cis-trans transformation of an organic receptor in a solid-liquid crystalline state reaction triggered by anion exchange

, p. 3219 - 3223 (2015)
An organic receptor [C28H24N4]2+ can be obtained with its unusual cis-form when it is ion-paired with a [Zn(dmit)2]2- coordination complex anion with the isolation of [C28H24N4][Zn(dmit)2]·2DMF (2). Compound 2 shows reversible cis-trans isomerization of the cationic receptor in a solid to solid transformation in a solid-liquid interface reaction.
