"Structurally reconfigurable two-dimensional conjugated polymers can give a new breadth to applications of two-dimensional materials in electronics."Dmytro Perepichka, McGill University

A study by a team of researchers from Canada and Italy, recently reported in a paper in Nature Materials, could usher in a revolutionary development in materials science, leading to big changes in the way companies create modern electronics.

The team’s goal was to develop two-dimensional materials, which are a single atomic layer thick, with added functionality to extend the revolutionary developments in materials science that started with the discovery of graphene in 2004. The study involved researchers from McGill University, Lakehead University and the Institut National de la Recherche Scientifique (INRS), all in Canada, and Consiglio Nazionale delle Ricerche, the national research council in Italy.

The team demonstrated the synthesis of large-scale two-dimensional conjugated polymers, and also thoroughly characterized their electronic properties. They achieved success by combining the complementary expertise of organic chemists and surface scientists.

This work opens exciting new directions, both theoretical and experimental. The integration of this system into a device (e.g. transistors) may lead to outstanding performances. In addition, these results will foster more studies on a wide range of two-dimensional conjugated polymers with different lattice symmetries, thereby gaining further insights into the structures and properties of these systems.

"This work represents an exciting development in the realization of functional two-dimensional materials beyond graphene," said Mark Gallagher, a physics professor at Lakehead University. "I found it particularly rewarding to participate in this collaboration, which allowed us to combine our expertise in organic chemistry, condensed matter physics and materials science to achieve our goals."

Dmytro Perepichka, a professor and chair of chemistry at McGill University, said they have been working on this research for a long time. "Structurally reconfigurable two-dimensional conjugated polymers can give a new breadth to applications of two-dimensional materials in electronics," he added. "We started dreaming of them more than 15 years ago. It's only through this four-way collaboration, across the country and between the continents, that this dream has become the reality."

Federico Rosei, a professor at the Énergie Matériaux Télécommunications Research Centre of the Institut National de la Recherche Scientifique (INRS) in Varennes, said they are excited about the results of this collaboration. "These results provide new insights into mechanisms of surface reactions at a fundamental level and simultaneously yield a novel material with outstanding properties, whose existence had only been predicted theoretically until now," he said.
