Повний текст джерелаIn the world of cosmetics and skin care products, there is a real need for innovation to find new materials with no impact on the consumer and the environment. In a bio-inspired approach, so-called "physical" colors offer a new way of creating colors without inorganic pigments. Indeed, today mineral pigments are the main source of coloring for cosmetic applications and their replacement represents a critical issue to limit possible exposure to potential nanoparticles.Sensitive to this challenge, LVMH Research worked with IPREM to design a solution resulting from the self-assembly of micro-hydrogels, known as microgels, with multiple stimulable properties, to produce color without pigments.These microgels, dispersed in water, have the capacity to spontaneously organize themselves during the evaporation of the solvent to produce very regular assemblies. These periodic assemblages, assimilated to "colloidal crystals", interfere with visible light and can lead to diffraction phenomena. The diffraction of visible light by the colloidal crystals leads to a so-called "physical" coloration.The work of this thesis project focuses on the design of hybrid microgels to enhance its photonic properties and lead to the formation of films after drying whose colors can be modified by a stimulus. The manuscript first presents the scientific context in which this work is carried out before discussing the synthesis process undertaken. In a second step, the photonic and stimulable properties are discussed in relation to the 3D organization of microgels within the film. Finally, efforts to transpose this technology into a cosmetic formulation are presented

Recently, we found that when a common planar chromophore like anthracene is substituted with the pentiptycenyl groups the resulting compound has the mechanofluorochromic (MFC), vapofluorochromic (VFC) and mechanofluorochromy (MFM) properties. We believe that the bulky pentitpycene groups prevent strong intermolecular interactions, which tend to make the system polymorphic and switchable by external mechano-stimuli. To further understand the mechanism of this system, we have investigated its position isomers, including 1,4-, 1,5-, 1,8- and 2,6- dipentiptcenylanthracene. The fluorescence spectra and time-dependent emission intensity were measured to compare their MFC and VFC properties by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy.
