Description
Summary:[Display omitted] •Preparation of organic nanofibers via electrospinning technique.•Cellulose acetate based nanofibers with porphyrins.•The effect of the metallation of porphyrins on nanofibers preparation.•Fluorescent and electrical conductive properties of electrospun nanofibers. The unique properties of electrospun nanofibers combined with functional compounds allow the preparation of novelty materials that can be employed in a wide range of applications. Among a vast number of polymers, Cellulose Acetate (CA) it is considered easy to electrospun and it was employed as the polymeric matrix, where free and iridium-porphyrins were incorporated. Two different solvent systems were employed according to the porphyrin used, and the best dispersion level on both the electrospun solution and the membranes, was achieved with the iridium porphyrin. The nanofibers with this porphyrin also exhibited electrical properties, while the fluorescence was quenched by the presence of specific axial ligands.
