1. Organic Hole-Transport Materials for Perovskite Solar Cells
Abstract : Research on perovskite solar cells (PSCs) has undergone dramatic development since the first cells were reported in 2009, and the past decade has witnessed a significant breakthrough on their power conversion efficiencies (PCEs) from 3.8% to 25%. READ MORE

2. Dynamics of Excitation Transfer and Charge Separation in Polymeric Semiconductors
Abstract : Dynamics of optically excited electronic states have been studied in solid films and solutions of semiconducting polymers and model compounds. Transient absorption, monitored in the spectral range from 0.9 eV to 2.5 eV with a time resolution of about 100 fs, was the main experimental technique. READ MORE

3. Direct and indirect mechanisms for aryl hydrocarbon receptor activation mediated by 6-formylindolo[3,2-b]carbazole
Abstract : The aryl hydrocarbon receptor (AhR) is mostly recognized for mediating the adverse effects of dioxins. In addition, endogenous activation of the AhR seems to have important biological functions. Several studies have demonstrated an activation of the receptor when no exogenous ligand was added.

4. Formation and metabolism of the tryptophan-derived 6-formylindolo[3,2-b]carbazole - a light-induced Ah-receptor ligand
Abstract : The aryl hydrocarbon receptor (AhR) is a ligand dependent transcription factor ubiquitously expressed in mammalian cells. It is a genetically ancient protein mostly known for binding the extremely toxic contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). READ MORE

5. Synthesis of indoles, bisindoles and indolocarbazoles : high affinity aryl hydrocarbon receptor ligands
Abstract : This thesis deals with the synthesis and reactions of indoles, bisindoles, indolocarbazoles and their derivatives. New methods for ring formation of planar, heterocyclic quinones, with the indolo[3,2b]carbazole or indolo[2,3-b]carbazole structures are described. READ MORE
