Functional fluorescent aramids: aromatic polyamides containing a dipicolinic acid derivative as luminescent converters and sensory materials for the fluorescence detection and quantification of Cr(vi), Fe(iii) and Cu(ii) Barrio-Manso, José Luis Calvo González, Patricia García García, Félix Clemente Pablos Lagartos, Jesús Luis Torroba Pérez, Tomás García Pérez, José Miguel This work describes the preparation of luminescent, high-performance aromatic polyamides. The fluorescent behaviour was achieved by preparing a diacid monomer containing a fluorescent dipicolinic acid derivative and polymerising it with commercially available aromatic diacid and diamine monomers to give polyisophthalamides. These materials can be structurally compared to commercialised meta-aramid fibres [poly(m-phenylene isophthalamide), brand names: NOMEX® and Teijinconex®]. The pendant fluorescent motif provided the material with a light green fluorescence and was found to be a selective host unit for cations of environmental, biomedical and industrial significance [Cr(VI), Fe(III) and Cu(III)]. 2024-02-05T18:14:36Z 2024-02-05T18:14:36Z 2013-05-21 journal article 1759-9954 10.1039/c3py00503h https://hdl.handle.net/20.500.14352/99160 1759-9962 https://doi.org/10.1039/C3PY00503H eng info:eu-repo/grantAgreement/MINECO/MAT2011-22544 info:eu-repo/grantAgreement/MINECO/CTQ2012-31611 info:eu-repo/grantAgreement/BU246A12-1 restricted access
