A team of researchers affiliated with both the University of California–Berkeley and the Kavli Energy Nanoscience Institute at UC, has developed a new covalent organic framework (COF) using boron and phosphorus—one that allows for higher connectivity than those now in use. In their paper published in the journal Science, the group describes their work in overcoming the limitations of the geometry of carbon bonds in COF architectures and how it led to the development of a whole new class of COFs.
