Solvatochromic AIE luminogens as supersensitive water

Solvatochromism 28,29 is the shift of the absorption spectrum of a molecule with varying solvent. The use of this phenomenon for the determination of β is based on the two-level microscopic model of the first hyperpolarizability, in which the infinite sum-over-states quantum perturbation expression for β is reduced to two states, the ground and excited states Solvatochromic dyes constitute a large class of environment-sensitive probes which change their color in response to polarity. Generally, they are push-pull dyes undergoing intramolecular charge transfer. Emission of their highly polarized excited state shifts to the red in more polar solvents. Excited-state intramolecular proton transfer is. Solvatochromism is a property of many different compounds in which color change is a consequence of solvent polarity. Strong blue fluorescent aminofuran was synthesized from the three-component reaction. It was found that the product is highly fluorescent and shows solvatochromic shift between 280 and 380 nm in solvents ranging from water to hexane. Solvent effects on the location of the. Common solvatochromic fluorophores exhibit a bathochromic fluorescence emission wavelength shift accompanied by intensity attenuation due to the presence of nonradiative decay pathways at the excited state. Such intrinsic but inevitable fluorescence quenching of solvatochromism impedes its applications to faithfully quantify local polarity, especially in a polar environment. Herein, we report. Solvatochromie. Unter Solvatochromie versteht man allgemein die Beeinflussung der Farbe eines Farbstoffes durch Lösungsmittel ( Solvens ). Die erkennbare Farbe der Lösung beruht auf Wechselwirkungen des Farbstoffes einerseits mit den Solvensmolekülen und auf den gegenseitigen Wechselwirkungen der Solvensmoleküle andererseits. Man.

Two-photon (TP) imaging with a donor-acceptor (D−A) type fluorophore is an emerging tool for bioimaging and sensing. However, current TP probes suffer from serious solvatochromic quenching in aqueous solution due to their strong intramolecular charge transfer (ICT) in excited states This solvatochromic probe, namely AggRetina probe, inherently binds to aggregated proteins and exhibits both a polarity-dependent fluorescence emission wavelength shift and a viscosity-dependent fluorescence intensity increase. Regulation of its polarity sensitivity was achieved by extending the conjugation length

An example of such a device is an array consisting of a metalloporphyrin , a pH indicator dye and a solvatochromic dye. The array is scanned with a flat-bed recorder, and the result are compared with a library of known VOCs. Vaporchromic materials are sometimes Pt or Au complexes, which undergo distinct color changes when exposed to VOCs The solvatochromic effect or solvatochromic shift refers to a strong dependence of absorption and emission spectra with the solvent polarity. Since polarities of the ground and excited state of a chromophore are different, a change in the solvent polarity will lead to differential stablization of the ground and excited states, and thus, a.
