The chemistry of heavy main group elements such as antimony bridges the gap between transition-metal and nonmetal/organic chemistry. Interested in the unique properties of antimony, we have explored the incorporation of this element into colored and fluorescent compounds to observe the influence of Sb on their photophysical properties. Recently, we have incorporated Sb groups into planar benzostibole heterocycles. The geometry of these heterocycles makes possible the direct interaction of the antimony atom with the π orbitals of the ring system, which directly affects photophysical properties such as color. Different substitutions of the benzostiboles can be used to create colorimetric sensors for fluoride anions based on Sb and to develop Sb-containing luminescent materials.
