Excited state interactions in calix[4]arene-perylene bisimide dye conjugates: Global and target analysis of supramolecular building blocks

The photophysical properties of two supramolecular building blocks oc and oc2 consisting of a perylene bisimide chromophore substituted with either one or two calix[4]arene units in the N-imide position as well as those of the reference compound oref without calix[4]arene substituents were investigated.
