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 AlPO 4 ‐5 single crystals through a physical vapor diffusion method. Raman spectroscopy indicates that the confined bromine structures mainly exist as (Br 2 ) n chains, individual Br 2 molecules, and a small amount of Br 3 − chains inside the channels of AlPO 4 ‐5 single crystals. Polarized Raman spectra demonstrate that the bromine molecular chains are approximately parallel to the channel direction of AlPO 4 ‐5 single crystals. Copyright © 2015 John Wiley & Sons, Ltd.
