5. 3. Palladium-Catalyzed Carbonylation and Arylation Reactions

   Author : Jonas Sävmarker; Mats Larhed; Gary Molander; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; palladium; carbonylation; styrene; amidine; aryl ketones; aryl sulfinates; ESI-MS; aryltrifluoroborates; Organic Pharmaceutical Chemistry; Organisk farmaceutisk kemi;

   Abstract : Palladium-catalyzed reactions have found widespread use in contemporary organic chemistry due to their impressive range of functional group tolerance and high chemo- and regioselectivity. The pioneering contributions to the development of the Pd-catalyzed C-C bond forming cross-coupling reaction were rewarded with the Nobel Prize in Chemistry in 2010. READ MORE

7. 5. ALL-OPTICAL CONTROL OF MOLECULAR FUNCTIONS - ENERGY TRANSFER SWITCHING AND INFORMATION PROCESSING

   Author : Magnus Bälter; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; white-light generation; molecular logic; spiropyran; photochromism; DNA-binding; diarylethene; energy transfer; all-photonic; fulgimide; dithienylethene; photoswitch; fluorescence modulation;

   Abstract : In this work, the photoswitching of molecular systems endowed with photochromic functionality have been investigated for the reversible photonic gating of excitation energy transfer (FRET) reactions as well as in application for all-photonic molecular logic. The presented systems involves the integration of photochromic entities within both covalent and non-covalent designs and serves to implicate photonic switching of molecular level phenomena. READ MORE
