G10: Functional dyes and related materials

About us


The research team specialized in synthesis and characterization of chromogenic materials has a solid background in applied color science with a significant expertise in dyes and pigments technology. Besides chromogenic materials based on classical dyes and pigments and their applications, our current concerns are centred on functional dyes, including hybrid structures for stimulated color changing materials, luminophores, and colorants for manipulation of light and energy transfer with suitable properties for emerging technologies (metamaterials, multifunctional structures, holography, organic conductors, light concentrators or E-textiles). Research areas: a) Synthesis of innovative materials based on functional dyes and pigments (stimulated color changing materials, luminescent systems for energy transfer, adaptive systems for light manipulation); b) Hybrid organic-inorganic coloring materials and film-forming materials for rigid and flexible substrates (photocatalytic coatings, anticorrosive film-forming materials, antireflective properties, resistant to overcoating); c) Conditioning of coloring materials as free flowing and easy dispersible powders, dispersion in liquid vehicles or by encapsulation in different matrices; d) Chemical structure investigation, evaluation of optical properties by molecular spectroscopy, color measurements and evaluation of color differences; e) Functionalization of textile materials (pretreatment, dyeing and finishing solutions, modifying of textile fabrics, providing functional effects — sensors, conductive, camouflage, self-cleaning).
