Optical absorption and fluorescence emission spectral studies of acridine in different solvents namely, carbon tetrachloride, dichloromethane, propan-2-ol, ethanol, methanol, acetonitrile, and N,Ndimenthyl formamide have been investigated. Oscillator strength and transition dipole moment of the acridine have been elucidated from the optical absorption measurement. The ratio of the excited state...

A reversible and pH-independent fluorescent ion optode is introduced with an ionophore and surface confined solvatochromic dye transducer doped onto microporous nylon membranes. The resulting film responds to K+ with excellent selectivity over the range of 10-7 to 10-2 M and a response time of t95 < 60 s above 10-6 M.

the solvatochromism of fluoresceine and its derivatives was studied in solvents of different hydrogen bond donor (hbd), hydrogen bond acceptor (hba), donor number (dn) and acceptor number (an) by their uv-vis spectra. results showed that position, intensity and shape of absorption bands change with type of solvent. these changes can be rationalized by solvatochromic parameters such as α, β, et ...

The Cover Feature illustrates how photoswitchable solvatochromic fluorophores can be used to distinguish lipid membrane domains with different ordering using super-resolution microscopy. More ordered membranes have lower water content than disordered so by detecting fluorescence in multiple spectral regions, the parts of mapped. design Kathryn G.

A hybrid quantum mechanical and molecular mechanical potential is used in Monte Carlo simulations to examine the solvent effects on the electronic excitation energy of the n → π(*) transition of acetone in ambient and supercritical water fluid, in which the temperature is in the range of 25-500 °C with pressures of 1-2763 atm. In the present study, the acetone molecule is described by the AM1 H...
