Molecular Keypad Locks: Synthesis and Optical Characterization of Fluorescent-Photochromic Molecules.
Title of Project
Molecular Keypad Locks: Synthesis and Optical Characterization of Fluorescent-Photochromic Molecules
Name of Advisor/s
Dr George Vamvounis
College of Science & Engineering
Summary of Project
Interest in protecting information on the molecular scale is increasing rapidly. For instance, the enhancement of security features in bank notes are becoming ever more challenging with counterfeit notes. Recently, we have developed a new series of molecular keypad locks based on photochromic fluorescent molecules (see: Phys. Chem. Chem. Phys., 2017, 19, 19984). In this system, we have shown that the fluorescence of a photochromic molecule could be modulated based on an entry code. However, further enhancement of the stability, reliability, processability and the complexity of the code within the security ink is still needed. To address these, you will:
- synthesize and structurally characterise new fluorescent photochromic materials.
- characterise the optical (absorption and emission) and thermal properties of your novel materials.
- work within a JCU (Prof. Ron White, Dr. Bronson Philippa) and an Australia-wide (http://aucaos.org.au/) interdisciplinary research team that is pushing-forward the next generation of organic semiconductors.
