High‐performance nanodielectric materials are built by C. Tang and co‐workers on page 5638 based on nano‐dipolar π‐conjugated oligomer thiophenecontaining polymers that exhibit high permittivity and low dielectric loss over a wide range of frequencies (100 Hz to about 10 MHz). Highly polarizable and fast‐responsive nano‐dipoles from nanoscale crystalline domains from π–π stacked oligomer thiophenes are believed to dictate the performance. These materials could be used to construct high energy‐density capacitors. The cover image is courtesy of Xiaodong Yin and Mitra Ganewatta.
