The present invention provides a supramolecular structure produced by the process comprising reacting a multi-generation dendrimer with a monomer, where the dendrimer comprises a core molecule, a plurality of interior generations spherically disposed around the core molecule and an outermost generation comprising a plurality of dendritic branches having terminal groups sufficiently reactive to undergo addition or substitution reactions, where the monomer introduces a labile bond and at least one cross-linkable moiety to the terminal groups of each dendritic branch, and where the cross-linkable moiety is bonded to the terminal group via the labile bond; crosslinking the cross-linkable moieties of adjacent dendritic branches; and cleaving the labile bonds, thereby freeing the dendrimer and forming a molecule encapsulated within a cross-linked shell molecule. The present invention further provides a process for the production of the supramolecular structures.

An acquisition method for multi-dimensional Fourier transform NMR data allows efficient accumulation of the data and provides artifact suppression in the acquired data under many circumstances. The method comprises performing an excitation pulse sequence having at least one evolution period wherein excited nuclei will at least partially relax. A transient generated from the pulse sequence is collected and stored, and the sequence is repeated with the evolution period varied in a predetermined manner. Transient information is collected for all values of the evolution period, and then the phase of at least on RF pulse may be varied and the procedure repeated. Subsequently transient information having common evolution periods may be signal averaged to obtain the NMR data. The method avoids residual magnetization effects under many circumstances, and significantly reduces acquisition time for data collection in spectroscopy or imaging environments.
