Macrocyles with novel functionalities as part of the core are important for molecular recognition and photophysical properties. 1 In this respect, chalcone structural moiety has an excellent potential to be a part of macrocyclic structures, since the photophysical properties of chalcones have been well exploited for various optical applications. 2., and So, we envisioned that the incorporation of chalcone moieties in macrocyclic core would be useful for molecular recognition ...
