Researchers Created Novel Molecules Using Olefin Metathesis


Researchers created a new type of molecular rotor using olefin metathesis, according to a study published on July 12, 2018.

This research was conducted by the researchers at the Texas A&M University. Dr. John A. Gladysz, who is a chemist, has been trying to develop novel molecules by mixing metals and carbon. Recently, Gladysz and his research group was successful in making a new type of molecular rotor, which is promising for the future development as a functional molecular machine capable of manipulating matter at atomic and subatomic levels and transforming multiple branches of chemistry, along with myriad related sectors and industries.

Olefin metathesis method was used by the research team for the synthesis of a series of platinum complexes with macrocyclic ring ligands that can flip over the core platinum atom in a conformation change reminiscent of Double-Dutch rope jumping. Major challenges were faced by the researchers and they successfully came over it to achieve unprecedented molecular motions, often centered on a core rotation that evokes a triple axel skating jump.

Moreover, computational methods were utilized to know what all motions can be understood by these newly developed molecules. Dr. Hemant Joshi, co-author of the study said, “Ours have three rings and therefore can undergo a ‘triple-jump-rope’ mechanism, which is unprecedented.” Furthermore, they are planning to use state-of-the-art computational models for the simulation of such rotation to understand the various factors that are responsible for controlling it to further hone their design.

Kharel, who just completed his Texas A&M Ph.D. said, “If researchers ever succeed to synthesize functional molecular machines, the possibilities are endless and range from molecular-level transport, or delivery of medication within the body, to manipulation of microscopic structures, or synthesis of chemicals, to data processing and storage.”
