The development of thermally activated delayed fluorescence (TADF) emitters for organic light emitting diodes (OLEDs) has been one of the most exciting and cutting-edge research fields in science. TADF based OLEDs with internal quantum efficiency (IQE) close to 100% are now routinely fabricated in the green spectral region. However, the blue and red emitters still show relatively low efficiency and instability and these problems need to be resolved in order to fully implemented TADF in OLEDs for display applications.
Currently, I am interested in resolving these problems by developing metal free TADF red and blue emitters which could achieve 100 % IQE and can be utilized for the fabrication of fully implemented TADF OLEDs. I am also interested in utilizing these blue and red emitting materials in Photodynamic therapy (PDT) for the treatment of skin cancer and acne. PDT is a popular treatment for nonmelanoma skin cancer with clearance rates between 70% and 100%. PDT using compact, lightweight, low-irradiation OLEDs has advantage over conventional treatments in term of being almost pain-free and "at home" therapy.
