Self-assembly is a useful strategy for the organisation of electron-donors and electron-acceptors into larger fibrous structures. The nature of these fibrous structures is key to the charge-transport properties of the materials obtained. We have been using short peptide-based low molecular weight gelators (LMWG) to self-assemble into one-dimensional fibres, which then bundle up together and entangle forming 3D networks.  Combining different gelators with donor or acceptor properties allows us to prepare interesting optoelectronic materials.<br/><br/>Here, we will show examples where mixing two gelators can result in co-assembly, where both gelators are present within the same individual fibres, or self-sorting, where only one type of gelator is present in each individual fibre. We will show how the morphology of the networks formed, the type and number of contacts between the acceptor and donor fibres are also critical for the optoelectronic properties of the material.<br/>
