## Abstract The synthesis and characterization of novel Schiff base liquid crystalline crown ethers prepared from the intermediates 4‐(4′‐alkoxylbiphenyl‐4‐carbonyl) benzaldehyde, __cis‐__ and __trans__‐4,4′‐diaminodibenzo‐18‐crown‐6 are described. The structure of these compounds have been well ch
## Abstract A new crown ether of 2,13‐dibenzothiazol‐2′‐yldibenzo[__b__,__k__]‐18‐crown‐6 was synthesized from 2,13‐diformyl‐ dibenzo[__b__,__k__]‐18‐crown‐6 with 2‐aminothiophenol. The binding behavior and the optical properties of the crown ether were examined through UV‐visible spectroscopy and
