Effects of cononsolvency on preferential adsorption phenomenon in poly(N‐isopropylacrylamide) ternary solutions

Published: November 2007

AbstractIn this work, the effect of cononsolvency on the phase transition and preferential adsorption phenomenon behaviors of poly(N‐isopropylacrylamide)/methanol/water ternary solutions was studied. In this cononsolvent system, the
$\Delta\overline{V}^{E}$, $\Delta\overline{G}^{m}$, and χ12 values show a nonlinear behavior and the minimum values of $\Delta\overline{V}^{E}$
and $\Delta\overline{G}^m$, while the maximum value of χ12 at ϕ2 is around 0.7. These facts indicated that one water molecule could directly bond with one methanol molecule to form the H2OMeOH complex. The H2OMeOH complex structure was found to remarkably affect the phase transition of poly(N‐isopropylacrylamide) (PNIPAM) in ternary solution. However, at the composition of mixed cononsolvent, ϕ2 < 0.2, the PNIPAM molecules may preferentially adsorbed pure water molecules; therefore, the LCST decreases slightly with composition of mixed cosolvent and this may be because of the small amount of H2OMeOH complexes in the mixed cononsolvent. While, at ϕ2 > 0.7, the PNIPAM molecules may preferentially adsorbed pure methanol molecules. PNIPAM ternary solutions were transparent and no transition occurred in this region. This indicates that the PNIPAM coils exhibited a much‐extended conformation in solutions. In contrast, at 0.2 < ϕ2 < 0.4 and 0.4 < ϕ2 < 0.7, PNIPAM molecules preferentially adsorbed water and methanol molecules, respectively, and also adsorbed large amount of H2OMeOH complexes. In these regions, the clathrate‐like structure around the side chain of PNIPAM molecule became more defected with adsorbing H2OMeOH complex. Therefore, we considered that the various thermodynamic behaviors between PNIPAM and mixture solvents must be related different preferential adsorption phenomena, which were mainly related to different degrees of polymer–solvent interaction and structures of solvent used. © 2007 Wiley Periodicals, Inc.

Axial‐Bonding Heterotrimers Based on Tetrapyrrolic Rings: Synthesis, Characterization, and Redox and Photophysical Properties
Authors: Giribabu Lingamallu , Kumar Challuri Vijay , Reddy Paidi Yella 
Published: November 2007

AbstractWe prepared two heterooligomeric arrays based on free base/metalloporphyrins at axial positions and a metalloid phthalocyanine as a basal scaffolding unit by using the axial‐bonding capabilities as well as the known oxophilicity of dihydroxytin(IV) phthalocyanine. Both heterotrimers were completely characterized by elemental analysis, MALDI‐TOF MS, and1H NMR (one‐ and two‐dimensional), UV/Vis, and fluorescence spectroscopy as well as cyclic voltammetry. The ground‐state properties indicate that there is minimal π–π interaction between the macrocyclic units. The excited‐state properties show that there is electronic energy transfer competing with photoinduced electron transfer from the singlet state of the axial porphyrin to the central metalloid phthalocyanine and a photoinduced electron transfer from the ground state of the axial porphyrin to the singlet state of the central metalloid phthalocyanine.
The impact of altered protein‐heme interactions on the resonance Raman spectra of heme proteins. Studies of heme rotational disorder
Authors: Rwere Freeborn , Mak Piotr J. , Kincaid James R. 
Published: November 2007

AbstractHeme proteins that have been reconstituted with certain hemins may contain substantial fractions of a minor component in which the orientation of the heme in the folded pocket differs from the major (“native”) conformation by a 180° rotation about the α‐γ meso axis. In fact, this minor component has also been shown to exist in some native proteins, including several mammalian globins. While resonance Raman spectroscopy has emerged as a powerful probe of active site structure of heme proteins, no systematic study has yet been undertaken to elucidate the specific spectral changes associated with this disorder. In the present work, combined analyses of the temporal behavior of both NMR and RR data sets have been completed to permit the extraction of a unique RR spectrum for the disoriented form, documenting rather dramatic changes associated with this rotational disorder. In addition, the use of protohemes bearing selectively deuterated peripheral methyl groups has permitted the association of the observed modes with specific fragments of the heme residing in the reversed orientation. The studies conducted here clearly illustrate the exquisite sensitivity of low frequency heme deformation modes to altered protein‐heme interactions. © 2007 Wiley Periodicals, Inc.
