Solvatochromic microcavity ion sensors

A novel copper(II) ion sensor has been developed, achieving both a broad dynamic range and high sensitivity, effectively addressing the limitations of conventional fluorescence-based detection methods. The sensor exploits the hydrolysis reaction between rhodamine B hydrazide (RBH) and copper(II) ions, with optical signal amplification enabled by a ...

Donor-acceptor substituted phenylethynyltriphenylenes – excited state intramolecular charge transfer, solvatochromic absorption and fluorescence emission

Beilstein Journal of Organic Chemistry, 2010
Several 2-(phenylethynyl)triphenylene derivatives bearing electron donor and acceptor substituents on the phenyl rings have been synthesized. The absorption and fluorescence emission properties of these molecules have been studied in solvents of ...

Solvatochromic spectroscopy of metamaterials

, 2019
For the first time, it is shown theoretically and experimentally, that immersing metamaterial into liquids with different refractive indices enables spectroscopy capable of distinguishing between different multipole contributions to metamaterial’s transmission and reflection spectra.
