Rational design of aminoanthraquinones for colorimetric detection of heavy metal ions in aqueous solution.
A family of water-soluble colorimetric chemosensors incorporating an anthraquinone signalling subunit functionalized with a polyamine chain that bears hydrophilic diethoxyphosphoryl moieties was prepared with the aim of assaying metal cations. The outstanding UV-Vis absorption properties of the 1-aminoanthraquinone chromophore allowed the efficient visual detection and quantification of copper(...
متن کاملModeling of multi-exciton transient absorption spectra of protochlorophyllide aggregates in aqueous solution.
Protochlorophyllide (Pchlide) is a natural porphyrin, a precursor of chlorophyll, synthesized by plants for its photosynthetic apparatus. The pigment spontaneously forms aggregates when dissolved in neat water solution. We present here calculations of the transient absorption spectra and its comprising components (ground-state bleach, stimulated emission, and excited-state absorption) for a str...
متن کاملThe absorption spectra of oestrone and related compounds in alkaline solution.
PEDERSON-BJERGAARD AND ScEou [1935] recently measured the absorption spectrum of oestrone in aqueous-alcoholic solution and found that the peak of the absorption band moved from about 2800 A. in acid or neutral solutions to about 2950 A. in alkaline solution, whilst the intensity also increased slightly. They attributed this change to enolisation of the 17-keto-group and the influence of the ne...

متن کاملAbsorption Spectra of Phytochrome Intermediates
Native phytochrome (124kdalton) was isolated from etiolated seedlings o f Avena sativa L. cv. Pirol (Baywa, Munich). From low temperature spectra (0 °C to — 165°C ) o f phytochrom e samples irradiated either with red or far-red light, spectra o f intermediates were calculated. Both absorption bands o f the phytochrome chromophore were reported. On the pathway P r i V r , native phytochrome does...
