What is it about?
A poly(p-phenyleneethynylene) polymer (PC[5]), featuring two π-rich cone-like calix[5]arene cavities (assembling cores) connected to a rigid p-phenyleneethynylene spacer, was synthesized by a Pd-catalyzed cross-coupling reaction. Upon variation of the host/guest molar ratio, two distinct types of assemblies were identified in solution: a 1:2 bis-endo-cavity assembly C10PC[5]C10 (PC[5]cap) and a polycapsular polymer network assembly PC[5]C10PC[5] (PC[5]net).
