Colorimetric and Fluorescent Sensing of SCN- Based on meso-Tetraphenylporphyrin/meso-Tetraphenylporphyrin Cobalt(II) System
An approach for colorimetric and fluorescent sensing of thiocyanate (SCN ) has been proposed based on the competitive-displacement strategy between meso-tetraphenylporphyrin (TPP) and meso-tetraphenylporphyrin cobalt(II) (CoTPP). In THF-water solution, TPP emits strong fluorescence at 651 nm; however, the fluorescence was quenched stepwise by CoTPP, and then restored by SCN , the detection limi...
متن کاملSpectroscopic Study of the Complexation of Meso-Tetraphenylporphyrin with -Acceptors DDQ and TCNE in Chloroform Solution
Formation of the molecular complexes between meso-tetraphenylporphyrin (TPP) and the p-acceptors 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) and tetracyanothylene (TCNE) in chloroform solution was investigated spectrophotometrically. The formation constants of the resulting 1:1 molecular complexes were determined using the Benesi-Hildebrand and Nash methods. The TPP-DDQ pro...

formation of the molecular complexes between meso-tetraphenylporphyrin (tpp) and the p-acceptors 2,3-dichloro-5,6-dicyanobenzoquinone (ddq) and tetracyanothylene (tcne) in chloroform solution was investigated spectrophotometrically. the formation constants of the resulting 1:1 molecular complexes were determined using the benesi-hildebrand and nash methods. the tpp-ddq proved to be more stable ...
متن کاملmeso-Tetraphenylporphyrin with a pi-system extended by fusion with anthraquinone.
Fusion with a 9,10-anthraquinone moiety was achieved to extend porphyrin's π-system. A bridged dihydroisoindole derivative was used to prepare the corresponding meso-tetraphenyltetraanthraquinonoporphyrin (Ph4TAQP) via a thermal retro-Diels-Alder reaction. The basic optical properties of the prepared new anthraquinonoporphyrin and its complexes with Zn and Pd were studied.
متن کاملEfficient Förster resonance energy transfer in 1,2,3-triazole linked BODIPY-Zn(II) meso-tetraphenylporphyrin donor-acceptor arrays.
Cu(I) catalyzed azide-alkyne cycloaddition (CuAAC) reactivity was successfully employed to synthesize three donor-acceptor energy transfer (EnT) arrays that contain one (Dyad), three (Tetrad) and four (Pentad) 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) donors connected to a Zn-tetraphenylporphyrin acceptor via 1,2,3-triazole linkages. The photophysical properties of the three arrays, a...
