“…Due to their unique (E) / (Z) / (E) isomerization process, the azobenzene derivatives found a wide applicability in many fields such as photoresponsive materials, optical data storage, surface relief gratings, optoelectronics switches, molecular machines, liquid crystal displays, etc. (Rau 1990a ; Kumar & Neckers 1989 ; Bouas-Laurent & Durr 2001 ; Natansohn & Rochon 2002 ; Angiolini et al 2011 ; Ebead 2011 ; Fayet et al 2010 ; Hamelmann et al 2004 ; Matczyszyn et al 2003 ; Kay et al 2007 ; Merino & Ribagorda 2012 ; Wang & Zhang 2012 ; Delaire & Nakatani 2000 ; Luftor et al 2009 ; Ishow et al 2006 ).…”

The molecular orbital calculations have been carried out to investigate the structure and stability of (E) / (Z) isomers of some azobenzene derivatives containing maleimide groups. A special attention has been devoted to the compound (E)-1, (E)-1-(4-(phenyldiazenyl)phenyl)-1H-pyrrole-2,5-dione, for which the available crystallographic experimental data have been used to validate the modeling structures computed at the theoretical levels AM1, PM3, RHF/6-31+G(d,p) and B3LYP/6-31+G(d,p). To this end, the discrepancy between experimental and calculated structural parameters has been ascertained in terms of root-mean-square deviation (RMSD). The quantum calculations at the level RHF/6-31+G(d,p) yield the most accurate results on (E)-1 structure giving a deviation error from crystallographic data of about 5.00% for bond lengths and 0.97% for interatomic angles. The theoretical electronic absorption spectra of azobenzene derivatives of concern have been computed by means of configuration-interaction method (CI) at the level of semi-empirical Hamiltonians (AM1 and PM3). Likewise, the molecular energy spectra, electrostatic potential and some quantitative structure activity relationship (QSAR) properties of studied molecules have been computed and discussed in the paper.Electronic supplementary materialThe online version of this article (doi:10.1186/2193-1801-2-586) contains supplementary material, which is available to authorized users.

“…As the free radical mechanism is easily accessible, an informational richness covers the synthesis, characterization and use of (meta)acrylic and styrenic (co) polymers, with side-chain azo sequence (Figure 9) [74,[88][89][90][91][92][93][94][95][96][97][98]. The versatility and easily processing of methacrylic polymers recommend these for NLO applications.…”

Nonlinear Optics - Nonlinear Nanophotonics and Novel Materials for Nonlinear Optics

The last decade of the last century is marked by a revolution in the synthesis of materials for optical and photonic applications, against the background of the growing need for new high-performance materials to increase the efficiency, reliability and speed of response linked to environmental aspects. The diversity of requirements and the optimization of the responses has led to a major dispute over the structure and composition of these materials: Inorganic or Organic, Natural or Synthetic, Hybrid or Pure, which has stimulated interest in the development of various architectures. Special attention shall be paid to establishing a fundamental relationship to correlate the non-linear optical response and chemical structure, especially for the category of organic materials- particularly polymers- distinguished by structural/compositional versatility and suitable for processing by simple technique which allows serial production. In fact, optical nonlinearity (NLO) is not an exotic phenomenon. Indeed, all materials are optically nonlinear if light is sufficiently intense. The synthesis of functional photonic organic materials is a major challenge of contemporary community of material scientists to imagine new functional materials based of” collective” phenomena by virtue of the “engineered” molecule- molecule interactions and spatial relationships. In this context, this paper aims to highlight the most important features concerning the structural - compositional relationship of polymeric materials used in optoelectronic and photonic applications.

“…This polymerization technique has also been used to obtain inorganic particles with controlled polymer hair size including gold, silica/silicon as well as glass surfaces. [18,[23][24][25] The RAFT agent can be immobilized on the substrate, then initiator and monomer are added together to start the radical polymerization or radicals can be generated on the surface itself by covalent attachment of an initiator and RAFT agent is added in a second stage, while monomer is introduced in the reaction mixture at the very latest stage. [20] Two methods are available for immobilization, the RAFT agent can either be attached via its R-group (anchoring side) or Z-group, the macroiniziator site, where reaction propagates (for a better understanding of the RAFT method a graphical representation of this approach can be found in in Figure 3).…”
