Self-assembled organic materials have recently drawn significant attention in the context of efficient energy, charge and ionic transport pro- cesses.[1] In the context of these self-assembly processes, phosphorus has proven to be a very versatile main group element beyond purely hydrocarbon-based materials. As an enzyme mimic, for example, phosphorus can act as coordinating center to form macrocycles and cages in which catalytic activities and energy transfer could occur.[2] Another inspiration for materials chemistry are phospholipids, a major component of cell membranes; researchers are now successfully copying and utilizing the amphiphilic character of phospho-lipid-analogues in self-assembled materials.[3]<\/p>\n\n\n\n

Our group and others, have recently established phosphole-based pi-conjugated systems as an intriguing new class of electronic materials with a variety of unique and versatile properties.[4] Within this stream of our research, we have started to further tailor the phosphole system by installing self-assembly properties and a investigating the energy and ionic transport properties of assemblies.[5,6] Our research in this area uses phosphaorganic conjugated scaffolds toward the self-assembly properties of the novel systems that we have termed \"phosphole-lipids\". To date we have accessed highly ordered liquid crystals as well as organogels based on these phosphole-lipids.[6,7] We were able to furthermore highlight their ability to noticeably respond toward external stimuli. The basic structure (phosphorus chemistry) - property (nano-\/micro-structure and energy transfer) relationship is currently being investigated and modeled toward further developing this intriguing class of compounds for a variety of potential applications in organic electronics.<\/p>\n\n\n\n
