Self assembled monolayer, as optical transducers, using spiropyran photochromic material
(2012-12-17)
The self assembled monolayers (SAM) have become in the most popular strategy for design and generate surfaces
characterizing by specific functional organic groups. The aimed of this work is applied this SAM as optical ...
Spectroscopy Analysis of the Ring Opening Reaction in Functionalized Spiropyran Films
(2012-12-17)
In this work we used the Fourier Transform Infrared spectroscopy and UV/Vis spectroscopy
to analyze the behaviour of self-ensemble films of spiropyran when the films were irradiated by
UV. In UV/Vis spectroscopy is ...
ATR spectroscopy applied to photochromic polymer analysis
(2012-11-23)
This work reports the use of infrared spectroscopy in the Attenuated Total Reflection (ATR) mode to analyze the interactions
between polymeric bases and the spiropyran. Infrared spectroscopy helps to understand the ...
Mapping the fluorescence performance of a photochromic-fluorescent system coupled with gold nanoparticles at the single molecule-single particle level
(American Chemical Society, 2014-04)
Single-molecule (SM) fluorescence microscopy was used to investigate the photochromic fluorescent system spiropyran-merocyanine (SP - MC) interacting with gold nanoparticles (AuNPs). We observe a significant increase in ...
Structural Analysis of Spiropyran Polimers using ATR Spectroscopy
(2012-12-17)
We have used infrared spectroscopy in attenuated total reflection (ATR)
mode to analyze the interactions between the polymeric base and solvent with a
photochromic material (spyropiran). We used cellulose acetate as ...

Photoswitchable Layer-by-Layer Coatings Based on Photochromic Polynorbornenes Bearing Spiropyran Side Groups
(2018-04-10)
Herein, we present the synthesis of linear photochromic norbornene polymers bearing spiropyran side groups (poly(SP-R)) and their assembly into layer-by-layer (LbL) films on glass substrates when converted to poly(MC-R) ...
Design and study of a photo-switchable polymeric system in the presence of ZnS nanoparticles under the influence of UV light irradiation
(MDPI, 2022)
Recent progress in the field of photosensitive materials has prompted a need to develop efficient methods to synthesize materials with basic intermolecular architectural designs and novel properties. Accordingly, in this ...
Photoisomerization of Azobenzenes and Spirocompounds in Nematic and in Twisted Nematic Liquid Crystals
(American Chemical Society, 2006-07)
Samples of a nematic mixture of ZLI1132 and of a twisted nematic mixture composed of ZLI1132 and chiral inductor S811, including 1%-10% (w/w) 4-N,N-dimethylaminoazobenzene (DAB), (4′-nitro)-4-N,Ndimethylaminoazobenzene ...
