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…

Pyrene Excimer-based Bis-triazolyl Pyranoglycoligands as Specific Mercury Sensors

AbstractThanks to supramolecular interactions of macrocyclic compounds with their guest ions or molecules, macrocycles have found wide applications in molecular and chiral recognition, separation, transportation, molecular machines, and so on…

Decoupling Fluorescence and Photochromism in Bifunctional Azo Derivatives for Bulk Emissive Structures

Bifunctional molecules that combine independent pushpull fluorophores and azo photochromes have been synthesized to create fluorescent structures upon light-induced migration in neat thin films. Their photochromic and emissive properties have been…
