Two-Dimensional Wideline Separation WISE NMR

As Tip measurements can provide valuable information on the local dynamics of polymer chains, measurements of this quantity are generally used to investigate the effects of blending on local motions in a polymer blend [49]. Molecular 

27 Characterization of Polymer Blends u/ith Solid-State NMR Spectroscopy 

As noted above, solid-state NMR spectroscopy is sensitive to local compositional, structural and dynamical environments in both ordered and disordered regions of 

In the CS spectrum of the C of C6o in C6oCF-A150, a well-defined splitting was observed which was an indication of a distortion from spherical symmetry. Fluctuations in the local magnetic field which arise from the dynamics of the Qo distortion, were determined from spin-lattice relaxation rate (1/Ti) measurements of Ceo- 

Nieuwendaal et al. showed that because of spin diffusion, NMR sensitivity to intermolecular correlations at the nanometer length scale, and its unambiguous chemical contrast, can be used to measure the phase behavior and domain sizes of BHJs of the P3HT/PCBM system [52]. When increasing the efficiency of OPVs, thermal treatment is generally thought of as a vital step in fabrication process however, the formation of needle-like PCBM crystallites which normally cause a lower effidency is one unfortunate consequence of thermal treatment.
