Synthesis and characterization of iodine molecular wires in channels of zeolite AEL single crystals

摘要

Well-aligned iodine molecular wires were synthesized by means of loading iodine molecules in the elliptical nanometer-scale channels of AlPO4-11( AEL) single crystals. Polarized Raman spectra reveal that the iodine molecular wires are oriented along the crystal channel direction by lining iodine molecules on the yz plane, where y and z represent the channel direction and the major-axial direction of the elliptical rings, respectively. Natural iodine wires are unstable, but they are very stable in the AEL channels. The template technique offers us an ideal platform to study the novel properties of these molecular wires.
