Abstract

An organic-inorganic hybrid solid [(dpaH) ⁺(NCS) ^-] (1) (dpa = 2,2'-dipyridylamine) based on an anionic template NCS ^- has been synthesized. Single crystal X-ray structural analysis reveals that NCS ^- templates assemble dpaH ⁺ units into a 3-D layer structure along the b axis through strong hydrogen bonding. Molecular salt 1 works as an anion-binder efficiently and selectively for recognition and sensing purposes in aprotic solvents. This receptor shows changes both in its UV-Vis absorption and fluorescence emission spectra upon the addition of F ^-, resulting in high selectivity for fluoride detection in CH ₃CN. It is promising to use these systems in various sensing applications.
