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).

Why is it important?
the control of supramolecular assembly and material morphology is an important field due to the applications in the realization of smart materials
Perspectives
supramolecular polymer network are a particular class of polymer in which the single polymer chain is preorganize to form the final structure with an high level of order. this characteristics are important for the design of new materials
