Electrochromic Effect

ABSTRACTAlkyl substituted poly(2, 5-thienylenevinylene)s were produced with a new synthesis. The polymers are soluble and processable and show a strong electrochromic effect in the visible spectral range.

New Synthesis

In this paper we report the results on synthesis of a composite biomaterial based on biphasic calcium phosphate (BCP) and poly-(DL-lactide-co-glycolide) (DLPLG). Besides, we have investigated the influence of new synthesis method on the structure and characteristics of the composite. The synthesis of biphasic calcium phosphate from Ca(NO3)2 x 4H2O and (NH4)3 PO4 in alkali environment was performed by means of precipitation technique. Composite material BCP/DLPLG was first prepared from commercial granules using chemical methods. Powdered polymer DLPLG was then homogenized at appropriate ratio with addition of biphasic calcium phosphate into the suspension. All samples were characterized by DSC, IR, X-Ray and SEM techniques.

Double Hydroxides

SummaryA new synthesis of Mg-Al double hydroxides is described, that gives products relatively low (0.8–1.0%) in CO2. The general formula [Mg1−xAlx (OH)2][(OH)x(H2O)0.81−x] with 0.23 ≤ x ≤ 0.33 is proposed. Cell parameters and thermal data are given. The c-axial length decreases with Al-content; this is attributed to increased electrostatic attraction between layers.

First Time

A new synthesis is reported for hexadecafluorophthalocyanineruthenium(II), F16Pc (2-) RuIIand hexadecachlorophthalocyanineruthenium(II), Cl16Pc (2-) RuII, is reported for the first time. These paramagnetic species, which contain no axial ligand, are quite reasonably soluble in a range of common organic solvents. We report and discuss electronic and vibrational (infrared and resonance Raman) spectroscopic, MALDI-TOF and magnetic data. In addition we report electrochemical data and use spectroelectrochemical methods to obtain the electronic spectra of these species in the phthalocyanine(1-), (3-) and (4-) oxidation states.
