Concise synthesis and characterization of 30-membered macrocyclic monomer for poly(ether ether ketone)

A 30‐membered macrocyclic arylene ether ketone monomer for poly(ether ether ketone) was synthesized by a two‐step method. The first step involves synthesis of a long bisphenol from hydroquinone and 4,4′‐difluorobenzophenone. The second step is the cyclization of the bisphenol with 4,4′‐difluorobenzo...

Description
Summary:A 30‐membered macrocyclic arylene ether ketone monomer for poly(ether ether ketone) was synthesized by a two‐step method. The first step involves synthesis of a long bisphenol from hydroquinone and 4,4′‐difluorobenzophenone. The second step is the cyclization of the bisphenol with 4,4′‐difluorobenzophenone. The pure macrocycle was isolated and characterized by IR, NMR, MS, TGA and DSC techniques. The X‐ray structure of the macrocycle was also determined.
