Research Highlights
New nickel complexes have helical shape
Together with Prof. Uttam Pokharel (Nicholls State University), we prepared six new nickel complexes with organic ligands, which fold and twist into helical shapes. The center of these complexes, between the two nickel atoms, is like a nano-scale “box”, but it’s empty. However, we are now designing complexes that will have room for other molecules to fit in the box. Then, we may be able to use them to transport molecules or ions from one place to another.
Relaxation Behavior of Bottlebrush Polymers
The segmental relaxation times of different bottlebrush polymer have been investigated
by dielectric spectroscopy and compared to their linear counterparts. Depending on
the side chain length, a slowed down process can be observed which levels out for
bottlebrush polymers having sufficiently long side chains. [Funded by the U.S. Department

Synthesis of well-defined polypeptoid mimics of poly(glutamic acid)
N-(3-tert-butoxy-3-oxopropyl) glycine derived N-carboxyanhydride was successfully synthesized and polymerized by ring-opening polymerization using primary amine initiators. The polymerization was found to proceed in a controlled manner over a wide range of molecular weights while maintaining a narrow molecular weight distribution. Mild acidic conditions readily unveil the carboxyl functionality to yield the pH-responsive, structural mimic of the biologically relevant peptide, poly(glutamic acid).
