Abstract

Squaraine dye molecules and their derivatives are gaining significant interest in the field of supramolecular chemistry, both in host-guest recognition and self-assembly. The unique structure and properties of squaraine molecules has led to extensive research into their use as sensors. This feature article covers the most recent studies (2004-2009) in the development, characterization, and application of squaraine dye-based molecular sensors, self-assembly, and their use in polymeric materials and biological applications.
