Raman spectroscopy of the one-dimensional atomic or molecular chains, which are the attractive building blocks of advanced nanoscale materials, is crucial in understanding the physical properties of the one-dimensional atomic or molecular chains. Here, we introduce the bromine into the one-dimensional channels of AlPO4-5 single crystals through a physical vapor diffusion method. Raman spectroscopy indicates that the confined bromine structures mainly exist as (Br2)n chains, individual Br2 molecules, and a small amount of Br3− chains inside the channels of AlPO4-5 single crystals. Polarized Raman spectra demonstrate that the bromine molecular chains are approximately parallel to the channel direction of AlPO4-5 single crystals. Copyright © 2015 John Wiley & Sons, Ltd.
