Abstract:

This report summarizes our progress in the STIR funded 9 month period in developing magnetic tweezers based approach to visualize the second-generation Grubbs catalyst G2 catalyzed ring opening metathesis polymerization ROMP at the single-polymer level in real time. Toward this goal, we have made the following progresses 1 Modification of the G2 catalyst for surface linkage to the magnetic particle or glass slide. 2 Set-up and testing of the MT instrument. 3 Manipulation of polynorbornene molecules. 4 Real-time ROMP of norbornene under no force load. These results provide the foundation and demonstrate the feasibility of using magnetic tweezers to follow and manipulate single-polymer growth during ROMP by a single catalyst molecule.
