Enhanced mechano-responsive fluorescence in polydiacetylene thin films through functionalization with tetrazine dyes: photopolymerization, energy transfer and AFM coupled to fluorescence microscopy studies

Physical Chemistry Chemical Physics (2021)

Luca Polacchi Arnaud Brosseau Régis Guillot Rémi Métivier Clémence Allain

The development of mechano-responsive fluorescent materials is essential for the design and construction of reliable and versatile sensors for mechanical stress. Herein, novel energy transfer-based systems with tetrazine fluorophore and a polydiacetylene (PDA) backbone are synthesized and studied comparatively to a simple polydiacetylene in the form of thin films. Their photopolymerization properties, energy transfer efficiencies and fluorescent response to nanoscale mechanical stimulation are assessed. It is pointed out that the self-assembling group on the PDA chain influences the geometrical arrangement of the chains and the film morphology and, as a consequence, the efficiency and kinetics of polymerization and the energy transfer efficiency. Moreover, we show that the strategy of introducing tetrazine fluorophore provides a new effective route of improving force detectability by fluorescence using polydiacetylenes as mechano-responsive units.

Fluorescence Microscopy Imaging of Light-Harvesting in Self-Assembled Nanofibers of Naphthalenediimides toward Perylenediimide Guests

ACS Applied Materials & Interfaces (2025)

Ramarani Sethy Arnaud Brosseau Takuya Nakashima Tsuyoshi Kawai Rémi Métivier

The self-assembly of a bichromophoric naphthalenediimide (NDI) into nanofibers showed efficient energy transfer (light-harvesting) to perylenediimide (PDI) molecules through a host-guest interaction, which can be visualized by microscopy using samples deposited on glass surfaces. In combination with atomic force microscopy, spectral, and polarization analyses, fluorescence imaging unveiled the inhomogeneity, packing defects, and relative spatial arrangement of PDI and NDI molecular units, which were found to affect the exciton mobility along the NDI nanofibers and the energy transfer efficiency from NDI to PDI guests. Fluorescence microspectroscopy shows that efficient energy transfer occurs from NDI nanofibers to isolated PDI molecules and their partial self-aggregates. The NDI nanofibers emit strong blue polarized emission, while the emission corresponding to PDI guest molecules is weakly polarized, indicating the local disruption of NDI chromophore-ordering upon PDI guest binding.

Giant Amplification of Photoswitching by a Few Photons in Fluorescent Photochromic Organic Nanoparticles

Angewandte Chemie International Edition (2016)

Jia Quan Su Tuyoshi Fukaminato Jean‐Pierre Placial Tsunenobu Onodera Ryuju Suzuki

Abstract Controlling or switching the optical signal from a large collection of molecules with the minimum of photons represents an extremely attractive concept. Promising fundamental and practical applications may be derived from such a photon‐saving principle. With this aim in mind, we have prepared fluorescent photochromic organic nanoparticles (NPs), showing bright red emission, complete ON–OFF contrast with full reversibility, and excellent fatigue resistance. Most interestingly, upon successive UV and visible light irradiation, the NPs exhibit a complete fluorescence quenching and recovery at very low photochromic conversion levels (<5 %), leading to the fluorescence photoswitching of 420±20 molecules for only one converted photochromic molecule. This “giant amplification of fluorescence photoswitching” originates from efficient intermolecular energy‐transfer processes within the NPs.

Functionalization and Crosslinking of Reduced Graphene Oxide Sheets by Multiple Tetrazine Units to Improve the Energy Storage in Supercapacitors

ChemElectroChem (2023)

Margarita Bosmi Ademola Adeniji Elise Michel Arnaud Brosseau Vitor Brasiliense

Abstract A multi‐tetrazine compound tailored for grafting on graphene sheets has been designed and investigated. It is composed of hydrogen substituted tetrazines involved in inverse Diels‐Alder demand cycloaddition reactions for grafting and a central dialkoxytetrazine to confer redox properties to the final material. The successful incorporation of this compound in reduced graphene oxide was demonstrated by elemental analysis, XPS, Raman spectroscopy, AFM, SEM and XRD. Cyclic voltammetry shows the redox activity of the remaining central tetrazine unit in graphene and allows to assess the specific capacity of the material. A significant increase in the specific capacity was found compared to pristine graphene and another tetrazine model compound bearing only one grafting unit. This result was assigned to an increase in the specific area in relation to bridges created between graphene sheets, as evidenced by AFM and XRD. The performance in energy storage were assessed in symmetrical Swagelok cells confirming the high impact of the functionalization on capacitance values.

β-Carotene/Limonene Derivatives/Eugenol: Green Synthesis of Antibacterial Coatings under Visible-Light Exposure

ACS Sustainable Chemistry & Engineering (2019)

Louise Breloy Célia Ait Ouarabi Arnaud Brosseau Pierre Dubot Vlasta Brezová

This study reports for the first time the use of β-carotene as a natural photosensitizer for both the cationic photopolymerization and thiol-ene click reactions under visible-light irradiation. In an all-green synthesis approach, this performing dye-based system leads to the cationic and thiol-ene polymerization of bio-based monomers, mono- and di-epoxy limonene, with very high final conversions, and appears as efficient as the common visible-light photosensitizers used in free-radical or cationic photopolymerization, that is, thioxanthone derivatives or camphorquinone. Effective antibacterial and tack-free coatings have been synthesized through the incorporation of a natural antibacterial agent (eugenol) in the limonene-derived polymer network. The antibacterial assays have demonstrated a tremendous effect of the eugenol-containing coatings against the adhesion of Escherichia coli (Gram negative) and Staphylococcus aureus (Gram positive).
