1. Controlling function by structure-intermolecular interactions and crystal engineering with N-donor ligands
Abstract : In the solid state regime, crystal engineering based on non-covalent synthesis requires an intuition about the intermolecular forces that can dictate the molecular architecture. Hydrogen bonds have become an instrumental tool in the self assembly and supramolecular chemistry. READ MORE

2. Nonlinear materials for optical power limiting : characterization and modelling
Abstract : High power laser pulses can be a threat to optical sensors, including the human eye. Traditionally this threat has been alleviated by colour filters that block radiation in chosen wavelength ranges. READ MORE

3. Dendron decorated chromophores for optical power limiting applications
Abstract : The need for protection of eyes and electro-optic sensors from powerful lasers has increased the need for new and better optical power limiting (OPL) materials that can protect against laser light. In this study the synthesis and characterization of dendron-coated OPL chromophores (porphyrins, thiophenes, and platinum(II) acetylides) are discussed. READ MORE

4. Synthesis and development of compounds for nonlinear absorption of light
Abstract : High-intensity light — for instance that from a laser — can be destructive, not only to the human eye, but also to equipment such as imaging sensors and optical communication devices. Therefore, effective protection against such light is desirable. READ MORE

5. Synthesis and optical characterization of optical power limiting platinum(II) acetylides
Abstract : Interactions between light and a molecule can result in reversible or irreversible changes in properties of both the light and the molecule. Of the many known interactions, nonlinear absorption is a process in which an intense light signal, for instance from a laser, can be moderated. READ MORE
