Acenes, especially tetracene derivatives, are used as singlet fission materials. The recent synthesis of Dodecaphenyl tetracene (showing end‐to‐end twist angles of 96–98 degrees) and twisted anthracene derivatives show that the synthesis of twisted linear oligoacenes is possible. Energy calculations and NICS‐X‐scan studies predict that twisted acenes may be better singlet fission materials compared to their planar analogues.
