| Abstract |
Self-assembly of ZnBr2 with 2,7-bis(isonicotinoyloxy)naphthalene (L) yields one-dimensional (1D) zigzag chains of [ZnBr2L] composition. This 1D chain ensemble forms unique suprachannels of 4.0 × 4.2 Å2 size via weak C−H···π and π···π interactions. A 350 nm ultraviolet irradiation affects host−guest conversion.
Diiodomethane molecules within the suprachannel structure of CHCl3·CH2I2@[ZnBr2L] were transformed into an unprecedented triiodide−iodine channel skeleton, HL+@[I3·I2]-. Specifically, two clear, quasi-reversible redox peaks were observed at +0.33 and +0.70 V versus Ag/AgCl in the anodic scan and at +0.19 and +0.62 V in the cathodic scan in acetonitrile for HL+@[I3·I2]-.
