Our research progress in heteroaggregation and homoaggregation of organic π-conjugated systems

Construction of crystalline homo/heteroaggregation at micro/nanometer level from organic π-conjugated systems is of great importance because the controllable morphologies (i.e., size, shape, and dimension) could provide diverse optoelectronic properties for different applications in the electrooptical devices. In this review, we summarize our recent progress in the self-assembly of micro/nanostructures of organic π-conjugated molecules via the heteroaggregation and homoaggregation strategies. We also discuss various factors (i.e., temperature, solvents, and surfactants) that affect the aggregation process through a surfactant-assisted reprecipitation method. Moreover, their physical properties and possible applications in electronics and biofields are illustrated.
