A compound of formula:
- and salts thereof
- where:
- R1 and R2 are the same or different and are independently selected from straight-chain and branched alkyl groups having 1-30 carbon atoms;
- and
- (1) both R3 are hydrogen;
- or
- (2) each R3 is the same group or different groups and both are independently selected from amine protecting groups;
- or
- (3) each R3 is the same group or different groups and each R3 is independently selected from halogenated straight-chain alkyl groups having 1 to 30 carbon atoms, halogenated branched alkyl groups having 3-30 carbon atoms, one or more alkoxyalkyl groups linked through an at least divalent linker to the pyrrole nitrogen, an optionally substituted aryl, an optionally substituted arylalkyl, and an optionally substituted heterocyclic group.
