A BODIPY aldoxime-based chemodosimeter for highly selective and rapid detection of hypochlorous acid
(Royal Society of Chemistry, 2013-09)
A BODIPY-based fluorescent probe integrated with an aldoxime unit shows a remarkable fluorescence "turn-on" response to hypochlorous acid (HOCl). The oxidative dehydrogenation of BODIPY aldoxime by HOCl results in a distinct ...
BODIPY-Au(I): A photosensitizer for singlet oxygen generation and photodynamic therapy
(American Chemical Society, 2017-05)
Upon complexation with Au(I), a photoinactive BODIPY derivative was transformed into a highly photoactive triplet sensitizer. Along with high efficiency in singlet oxygen generation (φδ = 0.84), the new BODIPY-Au(I) skeleton ...
Electrophilic cyanate as a recognition motif for reactive sulfur species: Selective fluorescence detection of H2S
(American Chemical Society, 2016-01-05)
An ESIPT-based fluorescent dye, 3-hydroxyflavone, is chemically masked with an electrophilic cyanate motif in order to construct a fluorescent probe for cellular sulfur species. This novel probe structure, displays an ...
A BODIPY-based fluorescent probe for ratiometric detection of gold ions: Utilization of: Z -enynol as the reactive unit
(Royal Society of Chemistry, 2016)
Using an irreversible intramolecular cyclisation pathway triggered by gold ions, a boron-dipyrromethene (BODIPY) based fluorescent probe integrated with a reactive Z-enynol motif responds selectively to gold ions. With the ...
Palladium-catalyzed alkoxycarbonylation of (Z)-2-En-4-yn carbonates leading to 2,3,5-trienoates
(American Chemical Society, 2011-02-18)
Pd(0)-catalyzed carbonylation of (Z)-2-en-4-yn carbonates in the presence of a balloon pressure of CO in an alcohol donates vinylallenyl esters with an exclusively E-configuration and in high yields. The fact that no such ...
Rhodium- and palladium-catalyzed 1,5-substitution reactions of 2-En-4-yne acetates and carbonates with organoboronic acids
(American Chemical Society, 2011-08)
Two methods involving the rhodium-catalyzed reaction of 2-en-4-yne acetates and the palladium-catalyzed reaction of 2-en-4-yne carbonates with organoboronic acids were investigated; both afforded exclusively the (E)-configured ...
A rare γ-pyranopyrazole skeleton: Design, one-pot synthesis and computational study
(Royal Society of Chemistry, 2016)
Drawing upon a consecutive amide coupling and intramolecular cyclisation pathway, a one-pot, straightforward synthetic route has been developed for a range of pyrazole fused γ-pyrone derivatives. The reaction mechanism ...
A BODIPY/pyridine conjugate for reversible fluorescence detection of gold(III) ions
(Royal Society of Chemistry, 2015)
We designed a "turn-on" type fluorescent probe based on a BODIPY-pyridine conjugate which exhibits high selectivity towards Au(iii) ions and, also responds to changes in the pH within the acidic pH range. The probe offers ...
A ratiometric fluorescent probe for gold and mercury ions
A fluorescent probe that displays a ratiometric fluorescence response towards gold and mercury ions has been devised. Emitting at a relatively longer wavelength, the conjugated form of the fluorescent dye transforms in the ...
A rhodamine/BODIPY-based fluorescent probe for the differential detection of Hg(ii) and Au(iii)
(Royal Society of Chemistry, 2014-02)
We described the design and synthesis of a molecular sensor based on a rhodamine/BODIPY platform that displayed differential fluorescence responses towards Hg2+ and Au3+ and demonstrated its utility in intracellular ion imaging.
