Q2 of FY 15 focused on continued work primarily on subtasks 2.2, 2.3 and 3.1. The modeling team focused their efforts on revising the model to predict 30 of the first 100 candidate molecules. After studying the effects of hydrogen bonding in Q1, the team has been focusing on the impacts of ion pairing and stacking of the molecules. At this point it is not clear if stacking impacts viscosity or just promotes a phase transition from the CO2BOL liquids to a glass. The synthesis team has continued their work by synthesizing and characterizing 8 of the first 13 candidate molecules. Key targets of the synthesis team include silane and fluorine derived molecules, to serve as representative molecules for new classes of CO2BOLs. These derivatives will be used as reference molecules to be used to derive new molecular libraries to study the impacts of cation/ion shielding and changes in acid/base strength. Currently 4 molecules have been tested visually for viscosity and CO2 uptake. A few of these derivatives show promise of reduced viscosity compared to the reference compound. The promising candidates are being scaled up in the lab to provide enough material for testing in Task 4
