PROJECT Description:

Conjugated polymers have received much consideration in the last two decades, due to their electro-optical properties, which made them suitable for using as active materials in optoelectronic devices.

A major drawback for their application in polymer-based devices is the rather large band gap, photochemical degradation, morphology evolution process, low electron affinity and high ionization potential. The construction of mechanically interlocked molecules, such as polyrotaxanes was also investigated as a method of further improvement of electronic properties through insulating the backbones of conjugated polymers. Even more, it is our special interest to explore the effect of these encapsulations, as an alternative approach to bring some benefits for optoelectronic applications of polyrotaxanes with conjugated polymers. As results few conjugated polyrotaxanes have been tested into light-emitting diodes and photovoltaic devices.
