授業アーカイブSince the pioneering work of Shirakawa, Heeger and McDiarmid in the 1970’s, the interest fororganic π-conjugated systems has grown tremendously. Indeedorganic materials offer thepossibility to process light-weight, flexible electronic devices, however, they have to satisfya large number of technical requirements in order to be stable and efficient in the device.The insertion of a heteroelement into the backbone has appeared as an appealing way totune the properties of the materials. Heterocycles like thiophene, pyrrole, and their derivativesare now widely used to modify chemical and physical properties of π-conjugated systems.Interestingly, while organophosphorus derivatives have been investigated for decades, their insertion into devices has only been achievedrecently. The high reactivity and toxicity of many P-derivatives is one of the reason but the ability of chemists to stabilize and protect theP-atom allowed the introduction of organophosphorus derivatives into opto-electronic devices. Here, we will report on phosphorus basedmolecular materials: their synthesis, their unique properties useful for organic electronic materials, and the devices that they have beenincorporated in so far. For example, we have shown that phosphorus heterocycles (phospholes, phosphetes, phosphepines…) are appealingbuilding blocks for the construction of π-conjugated systems. Effectively, the reactivity of the P-center allows a straightforward HOMO-LUMOgap tuning as evidence by photophysical and electrochemical studies. The coordination ability of the P-center allows unprecedentedcoordination-driven assembly of π-systems onto transition metals. All these physical properties make phosphorus heterocycles valuablebuilding blocks for the development of material for optoelectronic applications.
