Supramolecular-Wire Confinement of I2 Molecules in Channels of the Organic Zeolite Tris(o-phenylenedioxy)cyclotriphosphazene

Abstract

Efficient guest exchange: The organic zeolite analogue TPP⋅x(THF) (x=0.35–0.65) takes up I2 quickly when exposed to iodine vapor. The previously colorless crystals (a) color at the ends (b), and after 1–2 days the iodine has permeated all the way through the crystal (c). The conductivity values of the TPP⋅y(I2) crystals are of the same order as those of elemental I2. TPP=tris(o-phenylenedioxy)cyclotriphosphazene.
