Some particular deviations were specified: stabilizing homoconjugation of the CH2X substituents with the benzene π-electrons, or stabilizing interaction of polar groups with the tert-butyl group. However, most of the deviations are of an unknown nature: they are not due to solvation which affects ...

The free-radical polystyrene samples were dissolved in ortho-dichlorobenzene and monobromoperdeuterobenzene was added to the mixture. Polystyrene spectra were accumulated with pulse spacings of 2.1 and 3.5 s. The spectra were 1H noise decoupled and obtained after accumulation of 7-25 thousand ...
in a kit and a pharmaceutically acceptable composition. The method allows for preparing crystalline contrast agents with superior properties with easily available starting materials and with an economic and efficient process. The method allows for preparing crystalline contrast agents with exceptional water-...
This structure is formed as a result of stacking the π-system of a quasi-linear polymethine chain and the π-systems of adjacent planar benzene rings (see Figure 5 and details below) [22,23]. The currently fashionable idea of π-stacking [76] was first put forward by Hunter and ...
