Subpicosecond fluorescence anisotropy measurements are used to characterize the
rotational dynamics of coumarin 153 (C153) in 35 common solvents and eight solvent …

The photophysics and photochemical behavior of the phenoxazin‐3‐one dyes, resazurin
and resorufin, have been studied in aqueous solutions. The irradiation of resazurin in the …

After recalling the basic relations relevant to both steady-state and time-resolved
fluorescence polarization, it is shown how the values of steady-state polarized intensities …

The coumarins are a family of molecules that have been studied extensively because of
theirapplication as laser dyes and their substantial state-dependent variation in static dipole …

The absorption and fluorescence spectra of a highly fluorescent laser dye, Nile red, were
investigated in nematic solvents and isotropic liquids as a function of the solvent polarity and …

We report direct evidence for charge-induced long-range (ca. 100 μm) order in the room-
temperature ionic liquid (IL) 1-butyl-3-methylimidazolium tetrafluoroborate (BMIM+ BF4–) …

Room temperature ionic liquids (RTILs) exhibit several unusual properties, including the
ability to support an induced free charge density gradient, ρ f. Upon dilution with water …

Room temperature ionic liquids (RTILs) have a wide range of current and potential
applications, in areas ranging from supercapacitor energy storage to sequestration of toxic …

We report on changes in the magnitude and length scale of the induced free charge density
gradient, ρf, in three imidazolium room temperature ionic liquids (RTILs) with dilution by …

We have reported previously on the existence of charge-induced long-range organization in
the room-temperature ionic liquid (RTIL), BMIM+ BF4–. The induced organization is in the …
