Optical Sciences

Biomolecules and nanostructures

The Optical Sciences group studies the interaction of light and matter at the nanoscale. We do this by exploring ways to shape light and its environment. It's what we call active and passive control. Our current focus is on the interaction of light with biomolecules and nanostructures. We are part of Twente University's Department of Science and Technology and member of the MESA+ institute.
We participate in the EU-COST actions MP1102: Coherent Raman microscopy (MicroCor) and CM1202: Supramolecular photocatalytic water splitting (PERSPECT-H2O)

In substituted calix[4]-arenes-cyclophanes consisting of four phenol moieties connected by methylene bridges-the number and also the relative positions of the donor and/or acceptor pi- conjugated (D-pi-A) units can be varied by changing the configuration. The Figure illustrates the cone configuration. The molecular and thin-film NLO properties of three tetra-D-pi- A-substituted calix[4]arenes, including their orientation in thin films and the stability of their NLO properties, are described.
