Synthesis of a Monomer for Two-Dimensional Polymerization under Technically Feasible Conditions

Article abstract of DOI:10.1002/hlca.201800128

The synthesis of a promising 2D polymer uses the double decker rotor-shaped monomer 1, containing three anthracene moieties. To accelerate the development of the field of 2D polymers, this monomer was selected for scale-up that would allow its synthesis to be performed on the kg scale under technical conditions. This goal was achieved in collaboration with Polymaterials AG, Kaufbeuren, Germany. Not only was the synthetic route shortened, but each and every aspect of the remaining steps was streamlined so as to render them applicable to technical conditions. This involved the entire sequence to be adapted to metal instead of glass reactors and to a number of safety and toxicity concerns. Additionally, not only the utilization of the reactors had to meet strict efficiency requirements, but also the work-up procedures had to be facile. The whole sequence was then tested for feasibility under realistic conditions at Polymaterials AG. While this test afforded 130?g of monomer 1, it has the clear potential for the kg scale, supposed the safety equipment for the hydrogen evolution for the conversion of compound 2a?–?3 is available.
