摘要

本文介绍了一种化学交联型聚苯乙烯，它可以制备可逆机械压缩凝胶，作为 NMR 弱对准介质。这种凝胶可以在甲苯-d8 和吡啶-d5 等芳香溶剂以及 CDCl3 中成功溶胀，并提供了 1DCH RDC 和 13C-RCSA 的精确测量。

Reversibly Compressible Cross-Linked Polystyrene Gels, Compatible With Toluene-d₈ and Pyridine-d₅, for Measurement of Residual Dipolar Couplings and Residual Chemical Shift Anisotropies.

A chemically cross-linked version of polystyrene is presented here that allows the preparation of reversibly mechanically compressible gels as NMR weakly aligning media. The gels can be successfully swollen in aromatic solvents such as toluene-d₈ and pyridine-d₅, as well as in CDCl₃, and provided accurate measurements of ¹D_CH RDCs and ¹³C-RCSAs.

期刊介绍： MRC is devoted to the rapid publication of papers which are concerned with the development of magnetic resonance techniques, or in which the application of such techniques plays a pivotal part. Contributions from scientists working in all areas of NMR, ESR and NQR are invited, and papers describing applications in all branches of chemistry, structural biology and materials chemistry are published. The journal is of particular interest not only to scientists working in academic research, but also those working in commercial organisations who need to keep up-to-date with the latest practical applications of magnetic resonance techniques.
