21. Synthesis of Conjugated Polymers and Small Molecules for Organic Light-Emitting Devices and Photodetectors
Sammanfattning : Production cost and environmental impact are the two major concerns that are related to the conventional optoelectronic devices. It is desirable for the modern semiconductors that they are free of toxic/costly metals, they can be processed with low-cost solution-based methods, and their optical, electronic, and mechanical properties can be easily tuned depending on the target application.

22. Bifunctionalization of Small Organic Molecules Based on Fluorine Incorporation
Sammanfattning : The dissertation work that is summarized in this thesis describes novel syntheses of organofluorine compounds with a broad coverage of different fluorine-containing motifs.Chapter 2.1 covers works on the exploration of new trifluoromethylthiolating reactions of diazocarbonyl compounds.

23. Production and transformation of organic compounds from renewable feedstock : Catalytic approaches
Sammanfattning : This thesis is focused on the development of strategies for lignocellulosic biomass valorization. The thesis consists of two parts.The first part of the presented work is related to the catalytic fractionation of biomass (lignin-first approach) and the production of monomeric compounds from lignocellulose.

24. Enols and Allylic Alcohols as Building Blocks in Synthetic Organic Chemistry : Experimental and Theoretical Studies
Sammanfattning : The present thesis describes computational and experimental studies used to drive the reactivity of allylic and enol substrates towards new transformations. These synthetic methods give access to a number of organic molecules that may serve as important moieties in synthetic organic chemistry. LÄS MER
25. Carbocation Catalysis for Organic Synthesis
Sammanfattning : The most common view of carbocations in organic chemistry is that they are short-lived intermediates in several fundamental reactions, e.g. the classic SN1-reaction. LÄS MER
