Disclosed is a method of preparing terminally functionalized telechelic polymers using a cationic living polymer product or a terminal tert-chloride chain end of a carbocationic quasiliving polymer product, which comprises quenching the polymer product with a functionalized N-substituted pyrrole to thereby introduce the functionalized N-substituted pyrrole at the terminal reactive polymer chain end(s). A method is also disclosed whereby the N-substituent may be derivatized to a basic amine containing functional group. Also disclosed are the terminal functionalized polyisobuyl N-substituted pyrrole compounds where the polyisobutyl group is subsitituted at the 2 and 3 position of the N-substituted pyrrole.
A Versatile Method of Tethering Biomolecules to Pyrrole Precursors for Functionalized Magnetic Polypyrrole Core-Shell Nanoparticles
A mild and versatile method based on copper-catalyzed [3+2] cycloaddition (Meldal-Sharpless reaction) was developed to tether biomolecules, such as monosaccharides, biotin, cholesterol, or uridine to the N-atom of pyrrole. The required azido and alkyne functions can be placed in either reactant, i.e. in the pyrrole or the biomolecule. The products are interesting precursors for functionalized superparamagnetic polypyrrole core-shell nanoparticles.
