In acetonitrile solution, naphthalene and 1,2,4,5-tetracyanobenzene form charge-transfer (CT) complexes that self-assemble into hollow rods when the solution is dispersed in an ethanol–water mixture (a). Scanning electron microscope image of the rods (b) evidences their hollow nature. Upon excitation (330–380 nm), blue emission from the CT complex is observed (c). Addition of pyrene (0.015%) results in the emission of white light through an energy transfer process in the self-assembled rods (d, scale bars are 30 μm).
