1-7. (canceled)
A tyrosine-derived diphenol compound having the structure:
- wherein R1 is selected from the group consisting of —CH═CH—, (—CH2—)a, and —CHN(L1 L2), in which a has a value from zero to eight, inclusive, and L1 and L2 are independently selected from the group consisting of hydrogen and straight and branched alkyl and alkylaryl groups containing up to 18 carbon atoms, provided that L1 and L2 are not both hydrogen;
- b independently has a value between zero and eight, inclusive;
- and
- R2 is selected from the group consisting of straight and branched alkyl and alkyl-aryl groups containing up to 18 carbon atoms;
- and
- wherein at least one of R2 or, when R1 is —CHNL1L2, L1 or L2 contains at least one ether linkage.
