A base oil or lubricant additive has Structure I or Structure II as described herein. 2. The base oil or lubricant additive of claim 1 , wherein the base oil or lubricant comprises one and not more than one —R.3. The base oil or lubricant additive of claim 1 , wherein R claim 1 , R claim 1 , R claim 1 , R claim 1 , R claim 1 , R claim 1 , R claim 1 , and Rare independently chosen from —H claim 1 , methyl claim 1 , and R.4. The base oil or lubricant additive of claim 1 , wherein each occurrence claim 1 , Ris independently chosen from —C(O)—O—R.5. The base oil or lubricant additive of claim 1 , wherein at each occurrence claim 1 , Ris independently (C-C)alkyl.6. The base oil or lubricant additive of claim 1 , wherein at each occurrence claim 1 , Ris independently —((CH—CH)—O)—CH claim 1 , wherein n is 1 to 10; —(C-C)alkyl-O-phenyl; or —(C-C)alkyl-O-naphthyl.7. The base oil or lubricant additive of claim 1 , wherein X is —O—.8. The base oil or lubricant additive of claim 1 , wherein the base oil or lubricant additive is a lubricant additive.9. The base oil or lubricant additive of claim 1 , whereinthe base oil or lubricant additive has the structure I,{'sup': 1', '2', '3', '4', 'b, 'R, R, R, and Rare independently chosen from —H and —R,'}{'sup': b', 'b, 'the base oil or lubricant additive comprises one Rand not more than one R, and'}{'sup': 'b', 'sub': 8', '14', '22', '10', '15, 'Ris —C(O)—O—(C)alkyl, —C(O)—O—(C)alkyl, —C(O)—O—(C)alkyl, —C(O)—O—(C)alkyl, or —C(O)—O—(C)alkyl.'}12. The base oil or lubricant additive of claim 1 , wherein the base oil or lubricant additive is ocyl coumalate claim 1 , tetradecyl coumalate claim 1 , docosyl coumalate claim 1 , 4-tetradecyloxy-6-methyl-2-pyrone claim 1 , or 4-tetradecyloxy coumarin.13.
