Understanding solvation
(INT UNION PURE APPLIED CHEMISTRY, 2009)
The effects of solvents on different chemical phenomena, including reactivity, spectroscopic data, and swelling of biopolymers can be rationalized by use of solvatochromic probes, substances whose UV-vis spectra, absorption, ...
Probing the dependence of the properties of cellulose acetates and their films on the degree of biopolymer substitution: use of solvatochromic indicators and thermal analysis
(SPRINGER, 2010)
Although cellulose acetates, CAs, are extensively employed there is scant information about the systematic dependence of their properties on their degree of substitution, DS; this is the subject of the present work. Nine ...
Thermo-solvatochromism of merocyanine polarity probes - What are the consequences of increasing probe lipophilicity through annelation?
(WILEY-BLACKWELL, 2008)
The question raised in the title has been answered by comparing the solvatochromism of two series of polarity probes, the lipophilicities of which were increased either by increasing the length of an alkyl group (R) attached ...
Expedient, accurate methods for the determination of the degree of substitution of cellulose carboxylic esters: Application of UV-vis spectroscopy (dye solvatochromism) and FTIR
(ELSEVIER SCI LTD, 2011)
Two techniques, namely UV-vis- and FTIR spectroscopy, have been employed in order to calculate the degree of substitution (DS) of cellulose carboxylic esters, including acetates, CAs, butyrates, CBs, and hexanoates, CHs. ...
A monte carlo-quantum mechanics study of a solvatochromic pi* probe
(2016)
The solvation and the solvatochromic behavior of 5-(dimethylamino)-5'-nitro-2,2'-bithiophene 1, the basis of a pi* scale of solvent polarities, was investigated theoretically in toluene, dichloromethane, methanol and ...
Novel aminoquinoline-based solvatochromic fluorescence probe: Interaction with albumin, lysozyme and characterization of amyloid fibrils
(2020-02-01)
A novel aminoquinoline derivative (AQ) was synthesized and applied as a solvatochromic fluorescent probe to study proteins and their alterations. AQ is not fluorescent in aqueous solution but has its fluorescence quantum ...
Solvatochromism and electrophilicity
(ELSEVIER SCIENCE BV, 2011)
Solvatochromic dyes that exhibit a negative or a positive behaviour may be distinguished and their solvatochromism predicted with the aid of DFT-based indices, such as their electrophilicity omega, hardness eta and by the ...
Switchable Fluorescent and Solvatochromic Molecular Probes Based on 4-Amino-N-methylphthalimide and a Photochromic Diarylethene
(Wiley VCH Verlag, 2008-05)
New fluorescent photochromic compounds (1-H and 1-Boc)have been synthesized and characterized in different solvents.The fluorescence emission can be switched “on” and“off” with visible light and UV, respectively, by means ...
Solvatochromic Dipolarity Micro-Sensor Behavior in Binary Solvent Sustems of the (Water + Ionic Liquid) Type. Application of Preferential Solvation Model And Linear Solvation Energy Relationships
(Wiley, 2014-08)
The type of specific intermolecular and interionic interactions that are established when an ionic liquid is dissolved in water was here analysed. The study of the solvatochromic response of dipolarity micro-sensors based ...
Solvation in aqueous binary mixtures: consequences of the hydrophobic character of the ionic liquids and the solvatochromic probes
(ROYAL SOC CHEMISTRYCAMBRIDGE, 2012)
Information on the solvation in mixtures of water, W, and the ionic liquids, ILs, 1-allyl-3-R-imidazolium chlorides; R = methyl, 1-butyl, and 1-hexyl, has been obtained from the responses of the following solvatochromic ...
