Abstract

Permeation of metal ions is one of the most important events in biological signal transmission, especially for the development of sensors. In their Full Paper on page 2068 ff., Hendrik O. Lintang et al. demonstrate the first successful example of permeation of Ag+ ions into the congested channels of a mesoporous silica nanocomposite with an interpore distance of 4.1 nm consisting of a 1D columnar assembly of a trinuclear gold(I) pyrazolate complex. Exposure of Ag+ ions to the film causes a change in the phosphorescence of the nanocomposite from red to green, owing to the permeation of Ag+ ions into the nanochannel.
