 Research

1) Photochromic molecules and their potential application in the field of molecular logic devices

The supramolecular systems studied consist of photochromes covalently linked to other organic chromophores to constitute dyads or higher molecular architectures. The key operation of these constructs is the photoinduced isomerization of the photochromes between the two meta-stable forms. Upon isomerization, properties such as excitation energies, redox properties, electric dipole moment etc. experience substantial changes. These changes are harnessed to turn “on” or “off” given processes in the photochromic systems, e.g., electron and energy transfer reactions.

The switching of the transfer reactions mentioned above makes the photochromic systems function as all-photonic molecular devices such as single and double throw switches, several Boolean logic gates, half adders, encoders, decoders, multiplexers, demultiplexers, and code systems.

2) Photo-switched membrance penetration and DNA-binding of photocromic molecules

The possibility to photonically control the membrane penetrating and the DNA-binding abilities of photocromes is investigated. Due to the fact that both the structure and the charge distribution of a photochrome may change drastically upon isomerization, one of the two isomeric forms is often suitable for penetrating a membrane. Inside the membrane, e.g., in a cell, the photocrome can be photoisomerized to a structur with high DNA-binding affinity. Hence, the molecules are designed to function as light-activated pro-drugs.
