1. Phosphorus Centers in π-conjugated Systems
Sammanfattning : 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. LÄS MER
2. Novel Approaches to Phosphorus-containing Heterocycles and Cumulenes
Sammanfattning : Fast development in all areas of life and science over the last 50 years demands versatile, energy efficient and cheap materials with specific but easily tuneable properties which can be used for example in organic light emitting diodes (OLEDs), thin-film transistors, photovoltaic cells, etc. This thesis is devoted to the development of novel synthetic approaches to molecules with potential applications in the field of molecular electronics.

3. Low-Coordinate Organopnictogens : Synthesis and Optoelectronic properties
Sammanfattning : This thesis work is based on the development of novel organopnictogen compounds and the exploration of their potential applications in organic electronics. In particular, incorporation of phosphorus and arsenic into π-conjugated systems is known to modify the optoelectronic properties. LÄS MER
4. Studies on nucleic acids chemistry
Sammanfattning : 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. LÄS MER
