BLOCK COPOLYMER MICELLES

In a first aspect, the present invention relates to the use of a micelle of an amphiphilic block copolymer to modify a cell, wherein the amphiphilic block copolymer comprises one or more hydrophobic blocks and one or more hydrophilic blocks, wherein at le

Identification and quantification of polymerization defects in 13C-labeled sulfinyl and gilch OC1C10-PPV by NMR spectroscopy

By using selectively 13C-labeled sulfinyl and Gilch polymers, only noneliminated groups were demonstrated to be present in significant amounts (ca. 6.9%) in the sulfinyl conjugated OC1C10PPV. By means of a two-step elimination procedure, this amount could be reduced to a level less than 0.5%. In the Gilch route on the other hand, a tolane-bisbenzyl unit was confirmed to be the main structural defect. Furthermore, noneliminated groups were clearly present. For both polymerization routes no indications for other types of defects such as cross-links or branching, were detected while strong indications for carbonyl type end groups were found. The nature of all "defects" was elucidated by applying liquid 1D and 2D NMR spectroscopy and the amount was calculated based on fully quantitative 13C NMR spectra.
