Multicolor Emission of Small Molecule-Based Amorphous Thin Films and Nanoparticles with a Single Excitation Wavelength

Fluorescent organic nanoparticles (FON) made of small molecules recently arouse considerable interest in biomedical imaging and opto-electronics as potential microlasers or emitting displays.2 Their collective emission largely enhanced with respect…

Ruthenium(II) Complexes for Two-Photon Absorption-Based Optical Power Limiting

Long-lived excitation: Novel bifluorene-substituted 1,10-phenanthroline-based RuII coordination complexes are presented (see picture). They fulfil several requirements for optimized optical power limiting in the visible-NIR, as they are stable,…

Scanning-less wide-field single-photon counting device for fluorescence intensity, lifetime and time-resolved anisotropy imaging microscopy

A scanning-less single-photon counting system for FLIM and fluorescence anisotropy wide-field imaging is described and characterized in this paper. The two polarizations of the fluorescence are divided by a Glan prism and acquired at the same time…

Corrosion resistance of sol-gel coatings doped with an organic corrosion inhibitor: Chloranil

Hybrid sol–gel films have been prepared with diethoxydimethylsilane (DEODMS), methyltriethoxysilane (MTEOS) as a source of hydrolysable silane and tetra-propoxyzirconium (TPOZ) as a source of hydrolysable zirconium. In order to improve corrosion…

Generation of new fluorophore by Click chemistry: synthesis and properties of beta-cyclodextrin substituted by 2-pyridyl triazole

2-Pyridyl triazole substituted P-cyclodextrins, formed by a HUisgen [2+3] cycloaddition reaction between per-(6-azido)-beta-cyclodextrins and 2-ethynylpyridine, exhibited interesting solvent-polarity dependent fluorescence properties and acted as…

Electronic Excitation Energy Transfer between Two Single Molecules Embedded in a Polymer Host

Unidirectional electronic excitation energy transfer from a photoexcited donor chromophore to a ground state acceptor chromophore—both linked by a rigid bridge—has been investigated by low temperature high-resolution single molecule spectroscopy…

Assessment of cellular actin dynamics by measurement of fluorescence anisotropy

To study cellular actin dynamics, a cell-free assay based on fluorescence anisotropy was developed. Using G-actin-Alexa as a probe, we found that anisotropy enhancement reflects F-actin elongation. Anisotropy enhancement varies with the…
