“…Their potential use in optics or optoelectronics, such as for information storage, optical switching devices, surface relief gratings, nonlinear optics, etc has been motive the attention of the researchers and end users. [1][2][3][4][5][6][7][8][9][10] Large area of applications of azobenzene compounds is possible due to both its photoinduced properties and wide variety of the systems that it contained. Azobenzene chromophore has unique optical and photochemical properties.…”

Matrizes poliméricas com cadeia principal aromática e cadeias laterais formadas por unidades de poliestireno e polissulfona foram empregadas para construir filmes finos contendo moléculas de maleimidoazobenzeno, a fim de desenvolver novos materiais com propriedades responsivas. O comportamento fotocrômico do composto ativo foi estudado no estado sólido e em solução, para comparação. A isomerisação térmica cis-trans de cromóforos de azobenzeno em filmes finos de polímeros segue duas etapas cinéticas diferentes. Um processo de relaxação de segunda ordem (rápido e lento) ocorre em matriz de poliestireno abaixo de 70 o C, enquanto a isomerização térmica a 70 o C ou em temperatura mais alta segue cinética de primeira ordem. A quantidade de isômero cis correspondente ao estado fotoestacionário foi mais baixa em filmes do polímero do que em solução.Polymer matrices with aromatic main chain and side chain linked units (polystyrene, polysulfone) were employed to construct thin films containing maleimidoazobenzene molecules in order to develop new materials with responsive properties. The photochromic behavior of the active compound was studied both in the solid and solution state for comparison. The thermal cistrans isomerization of azobenzene chromophores in polymer films follows two different kinetic pathways. A double-exponential relaxation process (fast and slow) took place in polystyrene matrix under 70 o C while the thermal isomerization at 70 o C and higher follows a first-order kinetics. The cis isomer content corresponding to the photostationary state was found to be lower in polymer films than in solution.

“…Azo polymers have been shown to be excellent NLO materials (Yesodha et al, 2004;Delaire and Nakatani, 2000;Dalton et al, 1995;Burland et al, 1994). In azo systems, one has the additional advantage of using light to affect the chromophores.…”

“…The competing interpretations are evaluated in Chapter 4, where they are discussed at length. Many reviews of the remarkable body of experimental results are available Delaire and Nakatani, 2000;Yager and Barrett, 2001;Viswanathan et al, 1999).…”

“…This becomes significant in many nonlinear optical (NLO) studies. For instance, the chromophore's dipole moment can be used to orient with an applied electric field (poling), and the higher order moments of course define the molecule's nonlinear response (Delaire and Nakatani, 2000). In particular, the strongly asymmetric distribution of the delocalized electrons that results from push-pull substitution results in an excellent NLO chromophore.…”

“…[1,2] Molecules with π-extended conjugation exhibit high thermal stability and can present electroconductive, magnetic, and optical properties. [3][4][5] Arylene derivatives with extended π-conjugated systems, such as π-conjugated arylene oligomers, have triggered intense investigations due to their potential applications in photonics and optoelectronics, such as organic light-emitting diodes (OLEDs), solar cells, and field-effect transistors (FETs). [6][7][8][9][10] Those materials offer the possibility of tuning both the characteristics of the emitted light and the efficiency of the devices by means of simple chemical modifications of their structures.…”

The solubility, thermal, optical, and electrochemical properties have been investigated in detail. The title compounds are soluble in common organic solvents and emit a blue color both in solution and in the solid state, indicating that these oligomers might serve as potential materials in optoelectronic devices.
