Porphyrin-polyoxometalate hybrids connected via a Tris-alkoxo linker for thegeneration of photocurrent

Films on ITO of [N(C4H9)4]5H[P2V3W15O59{(OCH2)3CNHCO(ZnTPP)}] (ZnTPP = zinc(II)-tetraphenyl-porphyrin) were obtained by the Langmuir-Schaefer inverted transfer method.The films were characterized by UV-vis absorption spectroscopy, XPS, AFM, and…

An intrinsically fluorescent glycoligand for direct imaging of ligand trafficking in artificial and living cell systems

Glycoligands, sugar-based molecules able to complex metal cations, constitute a new class of molecules with great potential for biological and biochemical applications. To analyze their behaviour in a biological environment, we have synthesized an…

Photoactive chelating organic nanospheres as central platforms of bimodal hybrid nanoparticles

An innovative approach based on the combination of pre-formed nano-objects using photoactive chelating organic nano-platforms has been developed to elaborate hybrid functional nanoparticles. In this way, original “raspberry-like” structures made of…

One-photon excited luminescence of single gold particles diffusing in solution under pulsed illumination

Here we report on the visible luminescence of single gold nanospherical particles diffusing in water excited by a pulsed-laser at 488 nm. The signal studied by fluorescence correlation spectroscopy does not display the expected characteristics. The…

Reversible Quenching of a Chromophore Luminescence by Color Transition of a Polydiacetylene

A new reactive diacetylene molecule has been synthesized, incorporating a strongly luminescent chromophore, tetrazine (Tz). It readily polymerizes into the blue polydiacetylene (PDA) form, quenching the Tz luminescence already at concentrations ≤1 %…

Study and understanding of n/γ discrimination processes in organic plastic scintillators

For 50 years, it was assumed that unlike liquid scintillators or organic crystals, plastic scintillators were not able to discriminate fast neutrons from gamma. In this work, we will demonstrate that triplet-triplet annihilations (which are…

Fluorescent carboxylic and phosphonic acids: comparative photophysics from solution to organic nanoparticles

Phosphonic and carboxylic fluorescent nanoparticles have been fabricated by direct reprecipitation in water. Their fluorescence properties strongly differ from those of the corresponding esters where strong H-bonding formation is prohibited…
