Characterization of the Long-Range Internal Dynamics of Pyrene-Labeled Macromolecules by Pyrene Excimer Fluorescence
Farhangi, Shiva; Casier, Remi; Li, Lu; Thoma, Janine L.; Duhamel, Jean (American Chemical Society, 2016-12)The long-range internal dynamics (LRID) of 74 pyrene-labeled macromolecules (PyLMs) were characterized in four solvents representing a broad range of dielectric constants equal to 2.4 (toluene), 7.6 (tetrahydrofuran, THF), ... -
Long Range Polymer Chain Dynamics Probed with Pyrene Excimer Fluorescence
Farhangi, Shiva (University of Waterloo, 2016-09-27)A series of fluorescently labeled vinyl polymers bearing a C1-C18 side-chain (namely poly(methyl methacrylate), poly(butyl methacrylate), poly(octyl methacrylate), poly(lauryl methacrylate), and poly(stearyl methacrylate) ... -
Long Range Polymer Chain Dynamics Studied by Fluorescence Quenching
Farhangi, Shiva; Duhamel, Jean (American Chemical Society, 2016-09-13)Over the years, fluorescence quenching experiments have provided a robust analytical means to retrieve information about the internal dynamics of macromolecules in general and the long range polymer chain dynamics (LRPCD) ... -
Probing Side Chain Dynamics of Branched Macromolecules by Pyrene Excimer Fluorescence
Farhangi, Shiva; Duhamel, Jean (American Chemical Society, 2016-01-12)Four different pyrene-labeled polymers were prepared by radical copolymerization of n-butyl methacrylate (BMA) and 1-pyrenemethyl methacrylate (PyEG(0)-MA), 1-pyrenemethoxyethyl methacrylate (PyEG(1)-MA), 1-pyrene-methox ... -
Pyrenyl Derivative with a Four-Atom Linker That Can Probe the Local Polarity of Pyrene-Labeled Macromolecules
Farhangi, Shiva; Duhamel, Jean (American Chemical Society, 2016-02-04)The fluorescent probe 1-pyrenemethoxyethanol (PyMeEGOH) was designed to replace commercially available 1-pyrenebutanol (PyButOH) as an alternative fluorescent label to probe the internal dynamics and interior polarity of ...
