Amino methoxy difluoroboron diketonate as a multicolor and multi-responsive polymorphic fluorescence emitter

We here report the synthesis and stimuli-responsive fluorescence nature of amino-methoxy-difluoroboron diketonate, DFB-NH2, which was prepared via the Curtius rearrangement to introduce a primary amine on the phenyl ring. Thanks to the NH2 group,…

Quantitative photoacoustic spectral transformations in theranostic solid lipid nanoparticles labelled with increasing concentrations of a photoacoustic NIR BODIPY

Solid lipid nanoparticles (SLNs) have shown great capabilities for drug delivery and are therefore attractive theranostic candidates when labelled with an imaging contrast agent. This work aims to create the first SLNs labelled for photoacoustic (PA…

Comparison of macro x‐ray fluorescence and reflectance imaging spectroscopy for the semi‐quantitative analysis of pigments in easel paintings: A study on lead white and blue verditer

Abstract Macroscopic x‐ray fluorescence imaging spectroscopy (MA‐XRF) and reflectance imaging spectroscopy (RIS) are important tools in the analysis of cultural heritage objects, both for conservation and art historical research purposes. The…

Selective ion sensing in aqueous media with ESIPT active fluorescent probes – A particular case for hypochlorite detection

We report two ESIPT active novel fluorescent probes, 1 and 2, based on benzoxazole and benzimidazole units, respectively. Their sensing aptitude towards metal ions in aqueous media is reported. A specific response of 1 to Al 3+ and, to a lesser…

A Highly Sensitive and Selective Optical Sensor for the On-Line Detection of Cesium in Water

In this study, we have undertaken the development of two fluorescent sensors based on calixarene compounds for the purpose of detecting cesium in water. By introducing the sulfonate functional groups, we have considerably improved the water…
