New nickel complexes have helical shape

left side-- binuclear helices synthesized from Ni(II) salts; right side- helical sculpture that inspired the work

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

Segmental relaxation times of bottlebrush polymers. Chain lengths impact the dynamics of the relaxation times

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.

Synthesis of well-defined polypeptoid mimics of poly(glutamic acid)

N-(3-tert-butoxy-3-oxopropyl) glycine derived N-carboxyanhydride  polymerized by ring-opening polymerization using primary amine initiators. Image demonstarting a rapid polymerization with controlled Mn and low PDI with well defined structure.

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).
