Dr. Lei Zhang from the Briseno group synthesized a new class of polyacenes composed of eight angular fused rings, known as bistetracene (DOI: 10.1021/ja503643s). They find that the new angular geometry helps stabilize the molecules while retaining their excellent intrinsic charge transport properties. The team demonstrates that the soluble bistetracene derivatives are stable in air and processable in solution, and have low-energy band gaps and high charge-carrier mobility, which opens the door to exploring their use in mainstream applications such as solar cells and organic field-effect transistors.
