13C NMR spectroscopy of copoly(arylenephthalide) derivatives with diphenyloxide and terphenyl fragments in the main chain

Magn Reson Chem. 2013 Oct;51(10):621-9. doi: 10.1002/mrc.3991. Epub 2013 Aug 7.


(1) H and (13) С NMR spectral assignments have been provided for low-molecular reference monomers, poly(diphenyleneoxidephthalide) and periodic copoly(arylenephthalide) derivatives such as AB, ABB, and ABBB (where A = terphenylenephthalide and B = diphenyleneoxidephthalide) using (1) H-(1) H COSY, (1) H-(13) C HSQC and HMBC NMR techniques. Distinctive (13) C NMR chemical shifts of a main chain have been observed containing fragments of similar structures and lateral phthalate groups being part of various diads.

Keywords: 13С NMR; 1H NMR; 2D NMR; heterodiads; homodiads; periodic copoly(arylenephthalide) derivatives.
