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…

LipImage™ 815: novel dye-loaded lipid nanoparticles for long-term and sensitive in vivo near-infrared fluorescence imaging.

A new contrast agent, LipImage™ 815, has been designed and compared to previously described indocyanine green (ICG)-loaded lipid nanoparticles (ICG-lipidots®). Both contrast agents display similar size (50-nm diameter), zeta potential, high IC50 in…

Carbon fibre and Nano/micro (carbon nanotubes on carbon fibre) hybrid structures and their interface in advanced composites

In this chapter, we will briefly introduce in the first part some basic knowledge about CF properties, structure and fabrication process, as well as their application in composites. Then, we will present the modification of CF surface, and their…

Synthesis, characterization, morphological behaviour, and photo-and electroluminescence of highly blue-emitting fluorene-carbazole copolymers with alkyl side-chains of different lengths

Four novel phenyl-end-capped π-conjugated polymers comprising alkyl chains of different lengths were synthesized: the poly(9,9-dihexyl-2,7-fluorene-alt-9,9-dioctylfluorene) (P0), the alternating fluorene-carbazole copolymers P1 and P2 comprising 20%…
