The position
Organic RTP (ORTP) strategy for OLED applications is generally weakly explored area with numerous limitations, but having enormous potential for future development and commercialization if properly account for existing challenges. The main advantage of using ORTP in OLEDs is that triplets are involved into emission process without any additional stimuli like heavy metal atom effect, thermal activation or triplet-triplet annihilation. Thus, ORTP materials are intrinsically efficient with absolute internal quantum efficiency. However, the main challenges of ORTP materials preventing their usage in OLEDs are: 1) high phosphorescence lifetime observed usually in millisecond to second scale. 2) singlet and triplet excitons both able to emit light of different energy and this prevent narrow-band OLED emission. 3) covering a high-energy blue region of the visible spectrum. The limited number of materials demonstrating ultra-long blue ORTP are known to the moment, but short-living microsecond-scaled blue ORTP was not reported yet. Thus, the main goal of the project is to address the mentioned challenges and to design red, green and preferably blue purely organic (metal-free) room temperature phosphorescent materials demonstrating microsecond-scaled emission lifetime for future synthesis and implementation in OLEDs.
In order to realize the proposed project in most efficient way there are several important competences are required from potential candidate: 1) Deep knowledge in molecular spectroscopy and understanding the principles of light-matter interactions at advanced level; 2) Experience in modern computational techniques (especially in multireference ab initio approaches) for calculations of electronic structure and excited states of many-electron systems. 3) ability to analyse large data sets and to extract most important results from them; 4) expertise in systematization of results and building the logical schemes for purposeful molecular design.
The person we need
To be qualified to take employment as principal research engineer, you must have been awarded a doctoral degree or have a foreign degree that is deemed to be equivalent to a doctoral degree. The applicant must have or be about to complete postdoctoral training in the related field (computational chemistry, chemical physics or similar)) no less than 2 years and needs to be passionate about research. Problem solving ability and creativity are essential.
Experience in usage Gaussian, ADF, Dalton, ORCA, QChem etc. software and parallel computing is required. Skills in data processing and visualizing the results of quantum-chemical simulations are strongly desired (Molden, ChemCraft, VMD etc. software).
Experience in excited electronic state theory is very important, i.e. experience in TDDFT, TDA-TDDFT, spin-adapted and spin-flip TDDFT, CASSCF, CASPT2, ADC(n) methods is crucial for this position.
In order to communicate with experimentalists (synthetic chemists and experts in device engineering) the basic knowledge in organic chemistry and organic electronics are needed as well as ability to prepare reports, presentations and drafts of manuscripts.
Great emphasis will be placed on personal qualities and suitability.
