چکیده
In the present work, energy donor 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) is used for first time in combination with a pentacene dimer (Pnc2) to provide conjugate BODIPYPnc2 that features absorption throughout large part of solar spectrum. Upon photoexcitation, singlet excited state BODIPY transferred via intramolecular Förster resonance transfer (FRET). Subsequently, undergoes fission. this process, correlated triplet pair generated from coupling an intermediate state. The results show solvent polarity has influence on system, largest FRET rate (i.e., 7.46 × 1011 s−1) being obtained most polar (namely, benzonitrile) along quantum yield 207 ± 20%).

Förster, or fluorescence, resonance energy transfer (FRET) provides fluorescence signals sensitive to intra- and inter-molecular distances in the 1 to 10 nm range. Widely applied in the fluorescence imaging environment, FRET enables visualization of physicochemical processes in molecular interactions and conformations. In this paper, we report photoacoustic imaging of FRET, based on nonradiativ...
متن کاملQuantification of Förster resonance energy transfer by monitoring sensitized emission in living plant cells
Förster resonance energy transfer (FRET) describes excitation energy exchange between two adjacent molecules typically in distances ranging from 2 to 10 nm. The process depends on dipole-dipole coupling of the molecules and its probability of occurrence cannot be proven directly. Mostly, fluorescence is employed for quantification as it represents a concurring process of relaxation of the excit...

Förster resonance energy transfer (FRET) is a distance-dependent process that transfers excited state energy from a donor molecule to an acceptor molecule without the emission of a photon. The FRET rate is determined by the proximity between the donor and the acceptor molecules; it becomes significant only when the proximity is within several nanometers. Therefore, FRET has been applied to visu...
متن کاملUltramarine, a Chromoprotein Acceptor for Förster Resonance Energy Transfer
We have engineered a monomeric blue non-fluorescent chromoprotein called Ultramarine (fluorescence quantum yield, 0.001; ε(585 nm), 64,000 M(-1) x cm(-1)) for use as a Förster resonance energy transfer acceptor for a number of different donor fluorescent proteins. We show its use for monitoring activation of caspase 3 in live cells using fluorescence lifetime imaging. Ultramarine has the potent...

Förster Resonance Energy Transfer (FRET) is the phenomenon of non-radiative transfer of electronic excitations from a donor fluorophore to an acceptor, mediated by electronic dipole-dipole coupling. The transfer rate and, as a consequence, efficiency depend non-linearly on the distance between the donor and the acceptor. FRET efficiency can thus be used as an effective and accurate reporter of ...
