Fabrication of fluorescent holographic micropatterns based on the rare earth complexes using azobenzene-containing poly(aryl ether)s as macromolecular ligands

Abstract

In this work, on the basis of photoinduced surface relief gratings (SRGs) with the rare earth complexes using azopolymers as macromolecular ligands, a series of novel materials for fabricating rewritable fluorescent two-dimensional micropatterns, whose color can be easily adjusted by changing the species of the rare earth ions, are demonstrated. The rare earth complexes are prepared using a series of poly(aryl ether)s containing azobenzene chromophores and carboxyl group as macromolecular ligands and 1,10-phenanthroline as co-ligands. The fluorescence properties of the rare earth complexes and the influence of the contents of azobenzene chromophores on the fluorescent intensity are investigated by means of fluorescence excitation and emission spectroscopy. By exposing the films of the rare earth complexes to an interference pattern laser beam, SRGs can be formed on the films. Under the excitation, fluorescent patterns of the SRGs can be observed by the measurement of fluorescence microscopy.

Rare earth complexes using azobenzene-containing poly(aryl ether)s with different absorption wavelengths as macromolecular ligands: synthesis, characterization, fluorescence properties and fabrication of fluorescent holographic micropatterns

“…The preparation procedure of the rare earth coordination polymers was synthesized according to the literature. 19,22 As shown in Scheme 5, the synthesis route for the rare earth complex of Br-CPAE (Eu 3+ -Br-CPAE) was described for example as follows: Br-CPAE (0.002 mol) was dissolved in 10 mL of dried DMF. Then, a solution of Eu(NO 3 ) 3 (0.0016 mol) and Phen (0.0048 mol) in 10 mL of dried DMF was added.…”

Современное Состояние Разработки Светочувствительных Сред Для Голографии (Обзор)

“…Для получения люминесцирующих голографических решеток использовались металлоорганические азополи-меры XLIV, содержащие комплексы с редкоземельными элементами [152]. Применение фотополимеризующихся композиций, в состав которых включается азокраситель, испытываю-щий транс-цис-фотоизомеризацию, позволяет создавать необратимые фотонные структуры в виде объемных ре-шеток и двумерных фотонных гексагональных кристал-лов, а также обратимые фотопереключатели, свойства которых определяются транс-цис-фотоизомеризацией азокрасителя, находящегося в объеме заполимеризован-ного стекла [153].…”

Poly(arylene ether)s with aromatic azo-coupled cobalt phthalocyanines in the side chain: synthesis, characterization and nonlinear optical and optical limiting properties

“…Functionalized PAEs have received considerable attention due to their potential applications in optical storage materials, uorescent materials and proton-exchange membrane. [26][27][28][29] However, only a little nonlinear optical materials and optical limiting materials based on PAEs have been reported, [30][31][32] which need more development and research. In this paper, a novel optical limiting material with good thermal stability was designed and synthesized by introducing azobenzene chromophores and cobalt phthalocyanines into PAEs system.…”
