High thermal stability lubricants

A lubricant comprising:

• a multidentate lubricant comprising an anchoring moiety Ra attached to a plurality of sidechain moieties —(Rb—Re) according to the general formula:
• Ra—(Rb—Re)x;
• wherein Ra is a multivalent radical of valance x;
• wherein each Rb is, independently, a divalent moiety comprising the general formula:
• —OCH2CF2O—(CF2CF2O)b—C(R#)2CH2OH;
• wherein each R# is, independently, a hydrogen or a fluorine atom;
• wherein each b is, independently, from 1 to 10;
• wherein x is greater than or equal to 2;
• and
• wherein each Re is, independently, a hydroxyl (—OH) or a functional group including elements from Group 13-17 of the periodic table of the elements.
