NMR investigations of polytrifluoroethylene (PTrFE) synthesized by RAFT

Polymer Fluoride Sensors Synthesized by RAFT Polymerization.

A series of polymer chemosensors containing naphthalimide signal moiety and imide recognition moiety for the selective detection of fluoride ions (F(-) ) were synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. The polymer chemosensors display obvious absorption and fluorescence variations upon the addition of F(-) , which can be observed by both naked eyes an...

Investigations of Random Molecular Motions by NMR

The aim of this contribution is to demonstrate that NMR spin relaxation is an efficient method for the investigation of random molecular motions. Information on random motion is important for the characterization of liquids, polymers, and biological samples. Random motions are time-dependent phenomena and have to be treated with timedependent statistical mechanics. On the other hand, spin relax...

Structural investigations of poly(methyl methacrylate) by two-dimensional NMR

In the present paper a comprehensive microstructure analysis of PMMA based on the combination of one-dimensional and twodimensional (TOCSY, HSQC, and HMBC) NMR experiments is reported. To resolve complex resonance assignments, empirical chemical shift modeling supported by the 2D NMR spectroscopy has been done. Rigorous assignments of resonance signals have been done by investigating the one bo...
