supporting information; experimental part, p. 7882 - 7885 (2011/12/03)
Mesoporous silica nanoparticles were functionalized with an 18-crown-6 group as a gate molecule and the releasing capacity as a drug delivery system was controlled by the exchange reaction of "host-guest complex" with alkaline metal ions.
Crown-ether and azobenzene-containing liquid crystalline polymers: An influence of macromolecular architecture on optical properties and photo-orientation processes

scheme or table, p. 625 - 633 (2012/01/13)
A series of novel crown ether-containing photochromic comb-shaped liquid crystalline polyacrylates with different macromolecular structure of side groups were synthesized and investigated. Phase behavior, optical and photo-optical properties of thin spin-coated films of these polymers were studied. A special attention was paid to a comparative study of the photo-orientation phenomena occurring in the polymer films under a polarized light action. It was shown that complex formation with the potassium ions results in the decrease in degree of the photoinduced order that can be used for the creation of new materials for sensor devices.
