| 中文摘要 | several isomeric aromatic diester-diacids may appear as a result of the opening selectivity of anhydride groups towards the alcohol. h-1 n.m.r. was thus used to characterize the isomeric structure and to quantify the isomer composition. it was found that the isomer ratios quantitatively correlate with electron affinity of bridged dianhydrides and is independent of the alcohol structure used. furthermore, the h-1 n.m.r chemical shift of bridged diester-diacids was found to be a very sensitive probe of chemical nature of bridged groups and can be used as indices of the opening selectivity.
