Transient Brewster angle reflectometry of spiropyran monolayers [PDF]

open access: yes, 2010
Brewster angle reflectometry has been developed as a tool for determining the absorbance and refractive index changes in molecular monolayers containing spiropyran. The method is sensitive to changes in both the real and imaginary parts of the refractive

Preparation and photochromic properties of dye-doped aluminosilicate ORMOCER gels and coatings [PDF]

open access: yes, 1994
Aluminosilicate and ORMOCER gels and coatings containing photochromic dyes, 1, 3-dihydro-1, 3, 3-trimethylspiro-[2H-indole-2, 3\u27-[3H]-naphth-[2, 1-b][1, 4]-oxazine] (SO) and 1\u27, 8a\u27-dihydro-2\u27, 3\u27-dimethoxycarbonyl-spiro [fluorene-9, 1\u27-

Electronic structure calculations and physicochemical experiments quantify the competitive liquid ion association and probe stabilisation effects for nitrobenzospiropyran in phosphonium-based ionic liquids. [PDF]

open access: yes, 2011
Liquid ion association in ionic liquids (ILs) has been examined using a comprehensive series of electronic structure calculations that measure the relative extents of ion association and probe stabilisation for the photochromic dye nitrobenzospiropyran ...

Sensitization of Xanthophylls-Chlorophyllin Mixtures on Titania Solar Cells [PDF]

open access: yes, 2015
Co-sensitization of natural dyes on TiO2 for dye-sensitized solar cell (DSSC) was proposed between chlorophyllin (C) and xanthophylls (X at various volume ratios of C/X. Chlorophyllin is chlorophyll derivative providing -COOH groups essential for binding

Spiropyran modified microfluidic chip channels for photonically controlled sensor array detection of metal ions [PDF]

open access: yes, 2008
Microfluidic chips are particularly attractive for analytical purposes because they provide a convenient small platform for rapid analysis and detection.1 Furthermore, spiropyrans dyes can be used as photonically controlled, self-indicating molecular ...

Novel multifunctional materials based on ionic liquids: on demand micro-valve actuation for lab-on-a-chip applications [PDF]

open access: yes, 2009
We present the fabrication, characterization and performance as a micro-valve of four novel materials, ionogels, consisting in a polymeric structure with benzospiro-pyran units and phosphonium based ionic liquids. Each inonogel is photopolymerised in the
