Seeing is believing : Treatment of a tetrathiafulvalene‐functionalized calix[4]pyrrole 1 with chloride anions in CH 2 Cl 2 produces bowl‐like receptor 1 ⋅Cl − , which is able to encapsulate C 60 in a 2:1 barrel‐like manner. The color of C 60 ⊂( 1 ⋅Cl − ) 2 (green in CH 2 Cl 2 ) differs dramatically from its constituents (yellow and magenta for 1 and C 60 , respectively), thus allowing its formation to be monitored visually.
