Narcissistic versus social! In their Communication on page 15607 ff., G. Fernández et al. report on the self-assembly of two structurally related oligophenyleneethynylene (OPE) derivatives featuring polar or nonpolar peripheral chains and their remarkable narcissistic versus social self-sorting behaviour in aqueous media that can be controlled by concentration and solvent changes. Between 0.01 and 0.1 mM the mixture of both OPEs self-assembles into independent spherical aggregates, whereas a slight increase in concentration to 1 mM induces a co-assembly process, giving rise to large ribbon-like aggregates.
