Fluorinated aromatics and methods of using same

A method of transferring heat comprising:

• providing a device;
• and transferring heat to or from the device using a heat transfer fluid that comprises a fluorinated aromatic compound having structural formula (I):
• where Q is a carbon atom or a nitrogen atom;
• G is an oxygen atom or a sulfur atom;
• each R1 is, independently, a perfluoroalkenyl group having 2 to 11 carbon atoms and optionally comprises one or more catenated heteroatoms;
• each R2 is, independently, (i) a hydrogen atom or a fluorine atom;
• or (ii) a fluoroalkyl group or a fluoroalkenyl group having 1 to 9 carbon atoms and optionally comprises one or more catenated heteroatoms;
• each R3 is, independently, a hydrogen atom or a fluorine atom;
• x is 1-3;
• a is 1-2;
• y is 1-5;
• when Q is a carbon atom, z=6-y-a;
• and
• when Q is a nitrogen atom, z=5-y-a.
