Накратко на български

Проводимите органични полимери, като PEDOT и PPV, се изследват чрез добавяне на специални вещества за промяна на техните светлинни и електрически свойства. Това помага за създаването на по-енергоефективни органични светодиоди (OLED), които пестят електроенергия при осветлението.

Tuning both the photoluminescence and conductive properties of new COP materials

Since energy will be a key issue in the 21st century, we have to save energy and one possible way is the savings on lighting. For this purpose the use of organic light emitting diodes (OLEDs) could be a perfect choice, being far more energy efficient than incandescent lamps or fluorescent tubes. Most of the modern OLEDs have two important parts: an emissive layer and a conductive layer, which is often a so-called conductive organic polymer (COP). While most of the organic polymers have low electric conductivity and are insulators, COPs have unique electronic properties: they are conductors. Recent project focused on the synthesis of new conductive organic polymers (COPs), which are one of the most important part of the modern organic light emitting diodes (OLEDs). The main goal was to prepare COPs with tuneable properties, which could be achieved with application of tuneable doping agents. Cobaltabisdicarbollide [Co(C2B9H11)2]-, [COSANE]- anion is an excellent platform, since their redoxpotential can be tuned by halogen substitutions. The project focused on two kind of COP materials, namely the polyethylene dioxythiophene (PEDOT) and poli(p-phenylene vinylene) (PPV).

Цел на проекта

The main goal of this proposed project is the synthesis of new hybrid π-conjugated polymers for industrial use, which conductive and optical properties could be fine tuneable by the proper anionic metallacarboranes as doping agents. To achieve our goals two directions were chosen. In the first part we would like to investigate the effect of different boron clusters ([Co(C2B9HnX11-n)2]- X=Cl, Br, I) as doping agents on the conductive and photoluminescence properties of the poly(3,4-ethylenedioxythiophene) (PEDOT). Preliminary results suggest that the earlier used [Co(C2B9H11)2]- doping anion is redoxactive, thus it has a big influence on the formation and the properties of the polymer. Our expectation is that the halogen analogues ([Co(C2B9HnX11-n)2]-=Cl, Br, I) cover a wide range of redoxpotential, thus we can easily modify the properties of the new materials. During the second part we would like to tune both the conductive and photoluminescence properties of the poly(p-phenylene vinylene) (PPV). For this purpose different co-polymer planed to synthetized, which containing different amount of non-doped and self-doped monomer units. (In case of the self-doped polymer the doping anion is covalently linked to the monomer unit). We expect that the ratio of the non-doped and the self-doped has a strong influence both the conductive and photoluminescent properties, moreover the two different properties will be altered by the inclusion of functional side groups.
