Although bimane and bimane-derived fluorophores are well-known in the area of biological sensing, their use in supramolecular complexation and in applications derived from such complexation has been underdeveloped to date. This is true despite the fact that isolated reports indicate that bimane binds effectively in the hydrophobic cavity of β-cyclodextrin. Reported herein are results from our research groups that investigate precisely this topic: the supramolecular complexation of bimane and bimane derivatives in β-cyclodextrin, and how such complexation affects the chemical and photophysical properties of both system components. Moreover, such complexes have been used to achieve markedly enhanced properties in a range of applications, including in fluorescence-based chemical sensing and in the development of flame retardant coatings.
