摘要：

An expanded porphyrin [26]hexaphyrin(1.1.1.1.1.1) was exploited as a fluorescent chemodosimeter for Ag+ ions with high sensitivity and selectivity via near-infrared luminescence above 900 nm, a region that is free from optical interference in the visible wavelength range induced by the commonly used matrix and other organic compounds. The association constant for the Ag+-porphyrin complexation was evaluated by spectroscopic titration method to be 7.24 x 10(10) M-1. (C) 2008 Elsevier Ltd. All rights reserved.
