A rigid tribranched scaffold with three anthracene panels was synthesized using a stereocontrolled 1,3,5-triphenylbenzene core. Grinding a mixture of the rigid scaffold and perylene leads to the quantitative formation of a spherical assembly containing stacked perylene molecules in water. The wrapped perylenes exhibit unusual Y-type excimer-like emission (lambda(max) = similar to 500 nm) at roomtemperature. In contrast, an analogous assembly from a flexible tribranched scaffold and perylene shows E-type emission (lambda(max) = similar to 610 nm) from the wrapped perylenes under the same conditions.
