  2. 1. Controlling function by structure-intermolecular interactions and crystal engineering with N-donor ligands

    Author : Mohamed I D M Ghazzali; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; OPL; 10 phenanthroline]2 .; single crystal diffraction; intermolecular interactions; crystal engineering; Fe II coordination polymers; Schiff’s bases; porphyrins; intercalation; [ Ru tris-1;

    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

  4. 2. Nonlinear materials for optical power limiting : characterization and modelling

    Author : Hampus Lundén; Mikael Lindgren; Cesar Lopes; Bernd Eberle; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    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

  5. 3. Dendron decorated chromophores for optical power limiting applications

    Author : Robert Vestberg; KTH; []
    Keywords : Life sciences and physical sciences; polymer chemistry; optics physics; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP;

    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

  6. 4. Synthesis and development of compounds for nonlinear absorption of light

    Author : Tomas Kindahl; Bertil Eliasson; Sascha Ott; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Platinum acetylide; nonlinear absorption; optical power limiting; oxazole; quantum chemistry calculation; quantum chemical calculation; triplet absorption; organisk kemi; Organic Chemistry; fysikalisk kemi; Physical Chemistry; Quantum Chemistry; kvantkemi;

    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

  7. 5. Synthesis and optical characterization of optical power limiting platinum(II) acetylides

    Author : Marcus Carlsson; Bertil Eliasson; Jerker Mårtensson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Platinum acetylides; nonlinear absorption; optical power limiting; Sonogashira coupling; solution gels; thiophene; Organic chemistry; Organisk kemi;

    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
