PhD position (m/f/d): Novel Organic Emitters based on Thermally-Activated Delayed Fluorescence

Job Offer from February 21, 2023

We offer a position for a PhD/doctoral student for the synthesis and opto-electronic characterization of novel organic emitting materials based on the principle of thermally activated delayed fluorescence (TADF). These materials are of prime interest to the next generation highly efficient organic light-emitting diodes (OLEDs), now that heavy metal-based triplet emitters have become undesirable for reasons of sustainability. Thermally induced reverse intersystem crossing (RISC) allows for conversion into radiative singlet excitons of non-radiative (dark) triplet excitons, which in OLEDs typically form in abundance due to spin statistics. The envisaged emitters may be small molecular or polymeric, to be compatible with OLED fabrication via, respectively, thermal evaporation and solution processing.

The successful candidate will not only synthesize the emitters and fabricate the eventual OLEDs, but also study their electro-optical properties using a range of analysis tools, including steady state and time-resolved optical spectroscopy, ultraviolet photoelectron spectroscopy, cyclic voltammetry, as well as temperature-dependent electrical measurements on single charge carrier devices. For this reason, the project will certainly have a strong physical component and provides for the opportunity to acquire a broad skill set that benefits a career in both the chemical or physical direction, whether academic or industrial. The project will be carried out at the Molecular Electronics Division of the Max Planck Institute for Polymer Research (MPIP) (see:, which is worldwide one of the top research groups in organic semiconductor research and device physics. The candidate will have access to supervision and advice in all required disciplines.

We are looking for a doctoral/PhD student with i) a master in organic chemistry and ii) a motivation to develop him/herself in spectroscopy and electrical characterization. We only consider candidates with top-level scores for both the bachelor and master degree. Practical experience with organic synthesis, as well as the associated safety procedures is a must. The position is available with immediate effect. The application deadline is 31.03.2023. Please send applications per Email to: Dr. Jasper J. Michels ( Applications should include:

  • CV, including a publication list (if applicable)
  • motivation letter
  • transcript of your BSc and MSc course grades
  • contact details of at least two references

Incomplete applications will not be considered.

The MPIP, where the successful candidate will primarily work, is a world-renowned institute in macromolecular science and soft matter. The institute offers a highly international environment where the working language is English and the scientific and technical infrastructure is excellent. The access to resources and scientific expertise for this project provide every opportunity for development as an independent researcher. The PhD position is regulated by the Max Planck Society bylaws.
