1. Unconventional Modulation of Diarylethene Photoswitches
Sammanfattning : Light can be manipulated and modulated to fit a particular need or application, such as overcoming a spectral mismatch when facilitating a high energy photochemical reaction. This can be of use in various applications, including solar energy conversion and biological contexts. LÄS MER
2. Controlling the Fluorescence Properties of Diarylethene-based Photochromic Systems
Sammanfattning : Diarylethene (DAE) photoswitches are one of the most promising families of photochromic molecules because of their outstanding photophysical/photochemical properties. This class of compounds, which can photoisomerize between an open colorless and a closed colored form, has been applied in various fields in this thesis work, spanning one-color fluorescence intensity modulation, all-photonic full-color reproduction, light-induced color changes for molecular logic gates and information processing.

3. ALL-OPTICAL CONTROL OF MOLECULAR FUNCTIONS - ENERGY TRANSFER SWITCHING AND INFORMATION PROCESSING
Sammanfattning : 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. LÄS MER
