Diboron-containing fluorophores with extended ladder-type π-conjugated skeletons

Abstract

A series of ladder type π-conjugated diboron complexes 1–4 have been designed and synthesized by a very simple synthetic procedure. Single crystals of complex 3 were grown and the molecular structure determined by X-ray diffraction analysis demonstrated that this type of diboron ladder has a rather planar skeleton. All complexes possess very high melting points (275–383 °C) and decomposition temperatures (Td5: 343–400 °C), indicative of their high thermal stabilities. The electrochemical and photophysical properties as well as theoretical calculations were investigated, suggesting the possibility of these boron complexes as efficient emitters in optoelectronics.
