Tailor-Made Synthesis

 

 

To fulfil the complex functions in organic and hybrid thin layer devices, taylor made molecules and polymers such as light harvesting dyes, charge transport materials and nano particles are untertaken utilizing modern synthetic methods. In addition to conventional synthetic methods, enabling technologies such as microwave and flow reactions are used.

Self-Assembly and Morphology

 

 

The morphological control on a nanoscopic level determines the interface between the functional domains as well as the long term stability of organic devices. We achieve this on all length scales – from molecular to mesoscopic and macroscopic – using self assembly principle based on seggregation and aggregation forces by designing suitable functional molecules and block copolymers.

Energy and Electron Transfer Studies

 

 

The two fundamental complementary and competing processes in nature, as for example photosynthesis - energy and electron transfer - are also the basic physical processes in organic devices such as OLEDs und OPVs. We study these processes in model as well as real systems in close cooperation with our Physics colleagues. Equipments for kinetics and dynamics studies using time-resolved absorption and emission are available.

Organic Devices

 

 

We fabricate and characterise prototype organic and hybrid thin film devices, such as:

  • Organic Light Emitting Devices (OLEDs)
  • Organic Photovoltaic Devices (OPVs) and
  • Organic Field Effect Transistors (OFETs)
  • Space Charge Limited Current Devices (SCLC)
