MALDI mass spectral analysis demonstrates that the repeat unit consists of the biphenyl moiety (ONC6H3–ONC6H4). Four distinct fractions are isolated based on differential solubility characteristics. The primary differentiating features of these fractions appear to be their considerably different conjugation and branching characteristics. A radical mechanism, consistent with the formation of Wheland intermediates is proposed to account for the observed mass spec, IR, UV–Vis, EPR and size exclusion chromatographic data. Luminescence spectroscopy data is also provided demonstrating the white light emission exhibited by these polymers.}, number={Part A}, journal={Polyhedron}, publisher={Elsevier BV}, author={Wilcox, Robert J. and Folmer, Jacob C.W. and Kennemur, Justin G. and Martin, James D.}, year={2016}, month={Jan}, pages={35–43} } @article{wilcox_losey_folmer_martin_zeller_sommer_2015, title={Crystalline and Liquid Structure of Zinc Chloride Trihydrate: A Unique Ionic Liquid}, volume={54}, ISSN={0020-1669 1520-510X}, url={http://dx.doi.org/10.1021/ic5024532}, DOI={10.1021/ic5024532}, abstractNote={The water/ZnCl(2) phase diagram in the vicinity of the 75 mol % water composition is reported, demonstrating the existence of a congruently melting phase. Single crystals of this 3-equiv hydrate were grown, and the crystal structure of [Zn(OH(2))(6)][ZnCl(4)] was determined. Synchrotron X-ray and neutron diffraction and IR and Raman spectroscopy along with reverse Monte Carlo modeling demonstrate that a CsCl-type packing of the molecular ions persists into the liquid state. Consistent with the crystalline and liquid structural data, IR spectroscopy demonstrates that the O-H bonds of coordinated water do not exhibit strong intermolecular hydrogen ion bonding but are significantly weakened because of the water's coordination to Lewis acidic zinc ions. The O-H bond weakening makes this system a very strong hydrogen-bond donor, whereas the ionic packing along with the nonpolar geometry of the molecular ions makes this system a novel nonpolar, hydrogen-bonding, ionic liquid solvent.}, number={3}, journal={Inorganic Chemistry}, publisher={American Chemical Society (ACS)}, author={Wilcox, Robert J. and Losey, Bradley P. and Folmer, Jacob C.
