Squaraine dyes in molecular recognition and self-assembly

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.
