Functional polymeric systems constitute a huge family of novel hierarchical architectures categorized by different polymeric shapes, such as linear, brush-like, star-like, dendrimer-like and network-like ones; various components, such as organic-inorganic hybrid oligomeric/polymeric materials and metal-ligated polymers; different features, such as porous polymers; and diverse approaching strategies and driving forces, such as conjugated/supramolecular/mechanical force-based polymers and self-assembled networks [...].
