A white‐light‐emitting organogel is designed by the controlled self‐assembly of a bischolesterol‐functionalized OPV donor that allows slow energy migration and partial energy transfer in the gel state to an encapsulated acceptor. The white‐light emission occurs because of the combination of blue‐lig...
