DREAM or REALITY?

We have implemented the molecular design of triarylmethyl-based organic polymer network with magnetic ordering at about 10 K. The major drawback of triarylmethyl, as Moses Gomberg encountered, is its highly reactive nature, including high reactivity toward oxygen. For practical materials, radicals must be stable at ambient conditions.

The development of the high-spin triarylmethyl polyradical started with an efficient carbanion method for generation of polyradical. We have learned great deal from this research. Many difficult problems with the design, synthesis, and experimental procedures were encountered. We stumbled many times, and had to find our ways out. Luckily, we could keep going, in spite of the relatively low level of support and resources. At the end, this research provides wealth of knowledge and expertise for the next step in the quest for the practical plastic magnet. Now, we have a better understanding of how to design the system that would lead to magnetic ordering. What we need is an efficient method for generation of very high-spin stable radical; we are working on solving this problem.
