Chain Dynamics, Relaxation Times, and Conductivities of Bithiophene–Acene Copolymers Measured Using High Frequency Saturation Transfer EPR

Autor: Alicia M. Fraind, John D. Tovar, Lev R. Ryzhkov

Publikováno v: The Journal of Physical Chemistry B. 120:1033-1039

We present a study to probe the formation of localized aromatic sextets and their effects on the charge transport properties in polymers with acene cores. Bithiophene-acene copolymers containing benzene, naphthalene, or anthracene as acene cores were

The Ca(2+) sensor synaptotagmin-1 is thought to trigger membrane fusion by binding to acidic membrane lipids and SNARE proteins. Previous work has shown that binding is mediated by electrostatic interactions that are sensitive to the ionic environmen

Exceptionally high decarboxylation rate of a primary aliphatic acyloxy radical determined by radical product yield analysis and quantitative 1 H-CIDNP spectroscopy

Autor: Ryan Turncliff, Justin Sodano, Lev R. Ryzhkov, Alicia M. Fraind, Teri Fox

Publikováno v: Journal of Physical Organic Chemistry. 24:809-820

Symmetrical (RCO2CO2R; R = XCH2CH2) and asymmetrical (RCO2CO2R′; R = C9H19CH2CH2, R′ = CH3 or m-ClC6H4) primary diacyl peroxides were thermally decomposed under different conditions to analyze the decarboxylation rates of the thermally generated

Comparative Survey of Conducting Polymers Containing Benzene, Naphthalene, and Anthracene Cores: Interplay of Localized Aromaticity and Polymer Electronic Structures

Autor: John D. Tovar, Alicia M. Fraind

Publikováno v: The Journal of Physical Chemistry B. 114:3104-3116

We present a systematic study to understand to what extent the localization of aromaticity in an orthogonal sense to the main polymer conjugation pathway will influence the observed optical and electrical properties as the polymers undergo oxidation

Charge delocalization through benzene, naphthalene, and anthracene bridges in π-conjugated oligomers: an experimental and quantum chemical study

Autor: Lev R. Ryzhkov, John D. Tovar, Jean-Luc Brédas, Gjergji Sini, Chad Risko, Alicia M. Fraind

Publikováno v: The journal of physical chemistry. B. 117(20)

To understand the influence of orthogonal conjugation pathways fused directly to π-conjugated polymer backbones, we synthesized and studied three series of thiophene-based model compounds containing benzene, naphthalene, and anthracene peri-substitu
