A new class of periodic mesoporous organosilica (PMO) materials with a columnar π‐stacking arrangement of the framework organic groups has been prepared from disklike precursors with hydrophobic perylene bisimide (PBI) cores (see picture). The PBI‐bridged PMOs exhibit exciton coupling and efficient formation of mobile radical spins by electron doping within the pore walls.
