The use of macrocycles to develop charge-transfer complexes in the solid state was recently demonstrated. Here, the authors develop an on-off type vapochromic system toward positional bromoalkane isomers by the reassembly and disassembly of charge-transfer complexes between a pillar[5]arene and electron-deficient aromatic guests in the solid state.
