Patent number: 9011734Abstract: Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes.Type: GrantFiled: September 12, 2011Date of Patent: April 21, 2015Assignee: Pleotint, L.L.C.Inventors: Harlan J. Byker, Paul H. Ogburn, Jr., Douglas A. Vander Griend, Brad S. Veldkamp, Derick D. Winkle

Patent number: 8431045Abstract: Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes. In accordance with certain aspects of the present invention, thermochromic systems are disclosed comprising a transition metal ion with particularly useful ligands, such as phosphine compounds, tridentate ligands that coordinate through three nitrogen atoms, bidentate ligands, or ortho hindered pyridine monodentate ligands.Type: GrantFiled: May 22, 2012Date of Patent: April 30, 2013Assignee: Pleotint, L.L.C.Inventors: Harlan J.
