Photoswitchable fluorescent diheteroarylethenes: substituent effects on photochromic and solvatochromic properties.
Photoswitchable fluorescent diheteroarylethenes are promising candidates for applications in super-resolution molecular localization fluorescence microscopy thanks to their high quantum yields and fatigue-resistant photoswitching characteristics. We have studied the effect of varying substituents on the photophysical properties of six sulfone derivatives of diheteroarylethenes, which display fl...
متن کاملRed fluorescent protein with reversibly photoswitchable absorbance for photochromic FRET.
We have developed the first red fluorescent protein, named rsTagRFP, which possesses reversibly photoswitchable absorbance spectra. Illumination with blue and yellow light switches rsTagRFP into a red fluorescent state (ON state) or nonfluorescent state (OFF state), respectively. The ON and OFF states exhibit absorbance maxima at 567 and 440 nm, respectively. Due to the photoswitchable absorban...
متن کاملStudies on UV-Visible, Fluorescent Spectral Properties and Solvatochromic behavior of Naphthalimide Compound Containing Quaternary Ammonium
This paper presents the results of absorption spectra, fluorescence properties and the effect of solvents on UV-Vis spectra of dye quaternized 4-acetylamino-N-2-aminomethylpyridine-1,8-naphthalimide. The fluorescency of the dye was evaluated and its Stokes shift value was 6140 cm-1 in DMF. The solvatochromism behavior of the novel compound is investigated by studying its spectra in pure organic...
متن کاملReversibly photoswitchable nucleosides: synthesis and photochromic properties of diarylethene-functionalized 7-deazaadenosine derivatives.
Photochromic nucleosides were designed that combine the structural features and molecular recognition properties of nucleic acids with the light-sensitivity of diarylethenes. Target compounds 1a-c consist of a 7-deazaadenosine unit that is linked to a thiophene as the second aryl functionality via a 1,2-cyclopentenyl linker. These nucleoside analogues undergo a reversible electrocyclic rearrang...
متن کاملSubstituent Effects on the Physical Properties and pKa of Phenol
Substituent effects on the physical properties and pKa of phenol were studied using density functional theory [B3LYP /6-311G(d,p)] calculations. Substituents alter the physical properties of phenol such as the hydroxyl-group C-0 and 0-H bond lengths, the C-0-H bond angle, and the energy barrier to rotation about the C-0 bond, and also influence the hydroxyl-group pK •. Except for the rotational...
