“…The limited temperature range of our ε s data was extended using literature values and plotted in Figure for 1-octanol (blue circles) and 3-octanol (green crosses). Data from this work are also shown for 1-octanol (open circles, with linear best fit line) and 3-octanol (open crosses, connected by line as a guide to the eye), with vertical dotted lines representing the measured temperature range.…”

Describing Temperature-Dependent Self-Diffusion Coefficients and Fluidity of 1- and 3-Alcohols with the Compensated Arrhenius Formalism

et al. 2016

The location of the hydroxyl group in monohydroxy alcohols greatly affects the temperature dependence of the liquid structure due to hydrogen bonding. Temperature-dependent self-diffusion coefficients, fluidity (the inverse of viscosity), dielectric constant, and density have been measured for several 1-alcohols and 3-alcohols with varying alkyl chain lengths. The data are modeled using the compensated Arrhenius formalism (CAF). The CAF follows a modified transition state theory using an Arrhenius-like expression to describe the transport property, which consists of a Boltzmann factor containing an energy of activation, Ea, and an exponential prefactor containing the temperature-dependent solution dielectric constant, εs(T). Both 1- and 3-alcohols show the Ea of diffusion coefficients (approximately 43 kJ mol(-1)) is higher than the Ea of fluidity (approximately 35 kJ mol(-1)). The temperature dependence of the exponential prefactor in these associated liquids is explained using the dielectric constant and the Kirkwood-Frölich correlation factor, gk. It is argued that the dielectric constant must be used to account for the additional temperature dependence due to variations in the liquid structure (e.g., hydrogen bonding) for the CAF to accurately model the transport property.

“…Fluorophores like 1 , consisting of a molecular rotor element, two π-systems separated by a single bond, are known to be responsive to solvent viscosity. 17,22,23 Even though mixtures of dioxane and water are commonly used to control sample polarity, 24,25 they also impart small non-linear changes in viscosity. 26 Both changes in emission intensity of 1 and medium viscosity as a function of the water fraction in dioxane are plotted (Figure 2b).…”

Oligodeoxynucleotides Containing Multiple Thiophene-Modified Isomorphic Fluorescent Nucleosides

2013

View full text Add to dashboard Cite

5-(Thien-2-yl)-2’-deoxyuridine, an isomorphic fluorescent nucleoside analog, was incorporated into multiple positions within single stranded oligodeoxynucleotides. With minimal impact on duplex stability and overall structure, oligonucleotides containing three identical isomorphic fluorescent nucleosides in alternating or neighboring positions display enhanced, sequence-dependent on-signals for either duplex formation or dissociation.

“…A condensed phase shift of 0.9 eV is reasonable considering the values determined for gas phase and condensed phase benzene. 33 We only account for the shift in the ionization energies, since energy levels of the neutral DEHP molecule will only be slightly shifted by the weakly polar ( ε ∼ 4) 34 solvent DEHS. The corresponding AIE equals 8.6 eV and 7.8 eV for the gas and condensed phase, respectively.…”
