Hybrid aramids, Ir(III)-functionalized aromatic polyamides

Hybrid aramids, Ir(III)-functionalized aromatic polyamides
This work describes the preparation of high-performance hybrid luminescent aramids (aromatic polyamides). The new hybrid aramids are based on the commercial MPIA (poly(m-phenylene isophthalamide) and possess structural units bearing iridium(III) fragments which are responsible for the luminescent behavior. The aramids were casted into films, which were studied as luminescent color converters (LUCOs). In parallel, to get insight into the structure-properties relationships, hybrid aramid model, i.e., monomeric iridium(III) complex that mimic the behavior of the polymers, was prepared and studied. The new hybrid aramids were analyzed as LUCO devices to test their performance. The monomeric Ir(III) complexes are luminescent, whereas all the films prepared also show reasonable luminescent properties for novel lab prepared high performance aramids with outstanding thermal and mechanical properties.
