Supramolecular templating effect to steer the growth of covalent networks. (a) Schematic representation of the formation of kinked terphenyl polymer from BBP precursors. The Br adatoms produced from the first dimerization step produces a confinement template (b) that steers the regioselectivity of polymerization reaction leading to well-aligned linear polymers (c), as opposed to the branched polymers formed from nonbrominated 4Ph precursors (d). (e) The nanoporous phase of TPP(NH₂)₂ can perfectly accommodate C₆₀ molecules that are positioned in an adequate position to covalently bind to the neighboring NH₂ moieties upon annealing (f).
