“…The triple bonds in OPEs provide the opportunity to form shape‐persistent chromophores by imparting rigidity to the molecules, avoiding the rotational freedom observed for other π‐conjugated analogs. Their versatile functionalization possibilities, including variable repeating units, tunable shape and incorporation of various functional groups and (chiral) side chains, allow the fine‐tuning of the (chir)optical, supramolecular and materials properties [1c] . Moreover, the capability to place aryl ethynylene units at fixed angles around a phenyl ring makes OPEs structurally unique building blocks in terms of molecular shape versatility and persistence (Figure 1a).…”

Oligo(phenyleneethynylene)s (OPEs) have attracted widespread attention due to their remarkable (opto)electronic and photophysical properties, which have enabled numerous applications. The versatile functionalization possibilities of OPEs make them unique candidates to form various shape‐persistent geometries, including linear, triangular, rectangular, hexagonal and macrocyclic. However, as a result of this structural variety, it is oftentimes challenging to correlate molecular design with self‐assembly properties. In this minireview, we have classified OPEs based on their molecular shapes and correlated them with their self‐assembly behavior in solution. Particularly, we provide important insights into the aggregation propensity of the different molecular shapes and how to tune the association strength using various non‐covalent interactions. Our classification will enable a better understanding of the structure‐property correlation in OPEs, which is key to develop supramolecular functional materials
