(a) Synthesis of WSCC 238 and encapsulation of coronene; the X-ray structure of the (coronene)2⊂238 complex is shown. (b) Micrographs reveal that perylene does not enter the cell on its own (no fluorescence) but that blue emission corresponding to perylene was observed from the cytoplasm of HeLa cells after the incubation with an aqueous solution of perylene⊂238.
