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

    Author : Magnus Bälter; [2016]
    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.

  2. 2. All-Photonic Control of Biorelevant Processes using Molecular Photoswitches and Caged Compounds

    Author : Jesper Nilsson; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dithienylethene; azobenzene; drug release; kinase inhibitor; spiropyran; caged compound; live cell; spectroscopy; o-nitrobenzyl; photoswitch;

    Abstract : The development of light-controlled molecular tools for in situ regulation of biological activity holds great promise e.g. for resolving dynamic aspects of cellular signal transduction and to overcome inherent pharmaceutic limitations such as poor drug selectivity. READ MORE

  3. 3. Photochromism - Logic and Biologic Approaches

    Author : Martin Hammarson; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DNA-binding; molecular logic; dithienylethene; photochromism; DNA; photoswitch; spiropyran;

    Abstract : Photochromism is the light-induced colour change of molecules called photo-chromic compounds. The isomerisation causes changes in the electronic properties of the molecules and rearrangements of bonds which can be used in many more applications than the observed colour change. READ MORE

  4. 4. Synthesis and Photochemical Characterisation of Photoactive Compounds for Molecular Electronics

    Author : Behabitu Ergette Tebikachew; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoswitch; norbornadiene; photocleavable protection; Molecular electronics;

    Abstract : In this modern age of technology, communication is highly reliant on computing devices such as mobile phones and computers. The advent of artificial intelligence (AI) and internet of things (IoT) as well as the widespread use of user-generated contents (UGC) are demanding more computing power and large data storage.

  5. 5. Norbornadienes for Solar Thermal Energy Storage and New Applications

    Author : Ambra Dreos; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermal energy storage; molecular logic; Solar energy; molecular switch- es; energy conversion; quadricyclane; molecular keypad locks; norbornadiene;

    Abstract : The energy demand worldwide is steadily increasing, therefore it is fundamental to efficiently utilise renewable energy resources. Energy storage technologies are partic- ularly relevant in order to be able to exploit renewable energy resources such as solar energy, since these are typically intermittent and not evenly distributed.
