The synthesis of a series of star-shaped C3-symmetric amines and their inclusion complexation properties toward α-, β-, γ-cyclodextrins and their permethylated derivatives has been described. The star molecules comprise of 1, 3, 5-trisubstited benzene core and the points formed by (alkylamino)methyl or 4-((alkylamino)methyl)phenyl groups. The modes of host-guest interaction were studied by UV-Vis spectroscopy, ITC, 1H NMR and 2D-NMR (NOESY). It was found that star molecules containing (tert-butylamino)methyl, (adamantan-1-ylamino)methyl, 4-((isopropylamino)methyl) phenyl, 4-((tert-butylamino)methyl)phenyl and protonated 4-((adamantan-1-ylamino)methyl)phenyl points form strong host-guest complexes with β-cyclodextrin. It was also proved that the largest C3-symmetric guest can form complexes with bcyclodextrin with stoichiometry 3 which is required for construction of dendrimer supramolecular structures. None of the investigated amines forms a strong complex with permethylated cyclodextrins.

Propeller-shaped molecules based on a triphenylbenzene crux bearing three oligomeric phenylenevinylene branches have been designed; very large first-order hyperpolaris-abilities (up to ∥β∥ = 800 10-30 esu) were obtained while maintaining wide t
