A Schiff base type polymer containing phenanthrene and an aliphatic spacer in the main chain was prepared, its photophysical behavior diluted concentrated solutions as well film form studied by steady-state fluorescence spectroscopy. These data indicated that ground-state fluorescent aggregates were present films. Time-resolved measurements conditions showed biexponential decay implying different microenvironments around chromophore. Theoretical simulations predicted aggregation π-stack...
Abstract We focus this work on the theoretical investigation of block‐copolymer poly[oxyoctyleneoxy‐(2,6‐dimethoxy‐1,4phenylene‐1,2‐ethinylene‐phenanthrene‐2,4diyl) named as LaPPS19, recently proposed for optoelectronic applications. used that a variety methods, from molecular mechanics to quantum semiempirical techniques (AM1, ZINDO/S‐CIS). Our results show expected isolated LaPPS19 chains present relevant electron localization over phenanthrene group. found, however, could assemble in...
We studied the absorption line-shape of poly(p-phenylenevinylene) (PPV) films deposited via spin coating and Langmuir–Blodgett techniques with intent identifying conjugation length distribution in these two types films, a key morphological aspect conjugated polymer films. treated excitons as independent oligomer modeled spectra individual oligomers using simple expressions for size dependence gap energy, line-broadening factor, transition dipole moment Huang–Rhys parameter. validated by...
Este artigo é um recorte da dissertação de mestrado defendida em 2023 que teve o objetivo compreender as significações construídas pelas crianças acerca dos modos ser menino e menina existentes entre personagens algumas histórias literatura infantil adotam uma perspectiva contra-hegemônica gênero. O estudo como metodologia a pesquisa qualitativo-etnográfica com construcionista social. Para fundamentação teórica, foram utilizados autores Candido (2011); Corsaro (2005); Fernandes (2016);...
Polyfluorenes are promising materials for the emitting layer of polymer light devices (PLEDs) with blue emission. In this work, we report on PLEDs fabricated Langmuir-Blodgett (LB) films a polyfluorene derivative, namely poly(9,9-di-hexylfluorenediyl vinylene-alt-1,4-phenylenevinylene) (PDHF-PV). Y-type LB were transferred onto ITO substrates at surface pressure 35 mN m/sup -1/ and dipping speed 3 mm min/sup -1/1. A thin aluminum was evaporated top film, thus yielding sandwich structure...
Esse artigo traz um relato de experiência três professoras bebês e crianças bem pequenas da Unidade Educação Infantil Ipê Amarelo (UEIIA), Universidade Federal Santa Maria (UFSM), em momento distanciamento social devido à pandemia do coronavírus, que nos questionamos sobre como garantir os direitos das ser apoio às famílias. Diante disso, sabendo dos interesses comuns nossa turma, temos apostado na criação mini–histórias (FOCHI, 2019). As famílias têm relatado contentamento ao receber as...
