Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:1127-45-3) through the article.
Mol. devices capable of accessing different controlled conformational states, while optically signaling the occupied state, are attractive tools for nanotechnol. since they relate to both areas of mol. mech. devices and logic gates. The authors report here a simple mol. system that allows access to four distinct conformational and optical states. It is based on the regioselective complexation of metal ions to a heterocyclic ligand triad, which is dictated by the accessible coordination geometry and electrostatic properties of two distinct binding subunits. Thus, local conformational switching is brought about by tetrahedral coordination (of CuI) or octahedral coordination (of M2+ ions) to bidentate and tridentate binding subunits, resp. The shape modifications undergone represent an ion-controlled nanomech. device. They give controlled access to four different states that display different physicochem. (e.g. optical) properties and provide a basis for logic gate operations.
