摘要：

13C NMR studies of 4′‐R‐dibenzo‐18‐crown‐6 and 4′‐R‐dibenzo‐24‐crown‐8 showed that the substituent influence is transferred through the macrocycle to a remote aromatic ring. The transfer is due to steric effects and depends on crown ether complex formation. Copyright © 1990 John Wiley & Sons, Ltd.
