Abstract
AbstractCyclohexano anellated crown ethers, bis(phenylcyclohexano)‐18‐crown‐6 and benzo‐cyclohexano‐18‐crown‐6 with cis‐ and trans‐ configuration at the cyclohexane ring were synthesized. The phenyl substituted crown ethers react with formaldehyde to form a crosslinked resin. Depending on the reaction conditions, the benzo anellated crown ethers give soluble polymers and/or linear and cyclic oligomers. Cyclic products could be isolated. Crosslinked polymers were synthesized from benzo‐cyclohexano‐18‐crown‐6 using additionally to formaldehyde a dialdehyde or a diarly compound.
