(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
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 ...
Studies on the solvatochromic effect and NLO response in new symmetric bimetallic Rhenium compounds
(PERGAMON-ELSEVIER SCIENCE LTD, 2020)
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. ...
Solvatochromism and electrophilicity
(ELSEVIER SCIENCE BV, 2011)
Qualitatively and quantitatively different solvatochromism of the MLCT and MMCT absorption bands of centrosymmetric acceptor-bridged diiron (II, II) and diiron(III, II) cyanide complexes
(Elsevier Science Sa, 2002-07)
The energies of the metal-to-ligand charge transfer (MLCT) and metal-to-metal charge transfer (MMCT) absorption bands of a number of heterocycle-bridged diiron(II, II) homovalent and diiron(III, II) mixed-valent complexes ...
Polarization and solvatochromic shift of ortho-betaine in water
(ELSEVIER SCIENCE BV, 2008)
Betaine dyes are known to show very large transition energy shifts in different solvents. The ortho-betaine molecule - a simple two-ring prototype of the E-T(30) Reichardt dye - has been investigated theoretically from a ...
(Sociedade Brasileira de Química, 2010)
The effects of solvents on chemical phenomena is complex because there are various solute-solvent interaction mechanisms. Solvatochromism refers to the effects of solvents on the spectra of probes. The study of this ...
Photoswitchable fluorescent diheteroarylethenes: substituent effects on photochromic and solvatochromic properties
(Royal Society of Chemistry, 2014-01)
Photoswitchable fluorescent diheteroarylethenes are promising candidates for applications in super-resolution molecular localization fluorescence microscopy thanks to their high quantum yields and fatigue-resistant ...
Thermo-solvatochromism of merocyanine polarity probes - What are the consequences of increasing probe lipophilicity through annelation?
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 ...
