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.
