1. Phosphorus Centers in π-conjugated Systems
Abstract : Single-molecular electronics and organic material electronics are expanding research fields that ultimately aim for a vast variety of different applications, ranging from organic light-emitting diodes, to novel ways to improve the performance and decrease the size of electronics components. To achieve these goals, research has to be focused both on the development of functional molecules, but also on device fabrication. READ MORE

4. Studies on nucleic acids chemistry
Abstract : This thesis is divided into three parts: Part 1: Synthesis and conformational analysis of cyclic RNAs, and comparison with lariat RNAs modelling the lariat formed during processing of Group II and Nuclear pre-mRNA. Synthesis of a hexameric lariat RNA model with a tetranucleotidyl "2' → 5' loop" and a dinucleotidyl "3'-tail" has been accomplished. READ MORE
