Oligorotaxane radicals under orders [PDF]

, 2016
A strategy for creating foldameric oligorotaxanes composed of only positively charged components is reported. Threadlike components-namely oligoviologens-in which different numbers of 4,4'-bipyridinium (BIPY(2+)) subunits are linked by p-xylylene bridges,

2-(2,4,6-Trimethylphenyl)-1,10-phenanthroline [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
In the title mol-ecule, C(21)H(18)N(2), the mean plane of the benzene ring of the mesityl group forms a dihedral angle of 82.69 (4)° with that of the phenanthroline ring system. The crystal structure is stabilized by π-π stacking inter-actions between the phenanthroline system and the benzene ring of the mesityl group of a symmetry-related mol-ecule ...
