Abstract :A novel artificial receptor, 1,1`-insert ignore into journalissuearticles values(naphthalene-1,8-diyl);-3,3`- dibenzoyl-bisthiourea, based on a 1,8-naphthalene skeleton bearing bisthiourea groups was prepared and characterized by IR and 1H-NMR, 13C-NMR, and MS spectroscopic techniques. The compound proved to be an efficient and selective naked-eye detector for the fluoride, cyanide, and hydroxide ions in DMSO. The crystal structure of the title compound was examined by using X-ray crystallographic techniques and found to be crystallized in the monoclinic space group P -1 with the unit cell parameters: a = 8.1556insert ignore into journalissuearticles values(8); Å, b = 12.0127insert ignore into journalissuearticles values(11); Å, c = 13.2081insert ignore into journalissuearticles values(11); Å, a = 109.510insert ignore into journalissuearticles values(7);°, b = 95.390insert ignore into journalissuearticles values(7);°, g = 103.660insert ignore into journalissuearticles values(7);°, Z = 2. The intramolecular N-H...O hydrogen bonding interactions between the N-H and the oxygen atom of C=O groups support a 1,1`-insert ignore into journalissuearticles values(naphthalene-1,8-diyl);-3,3`-dibenzoyl-bisthiourea framework. Moreover, the combinations of N---H...S bonds produce R22 insert ignore into journalissuearticles values(8);rings.
