the equilibrium constant of adduct formation between some triorganotin chloride of the type r3sncl (r=c6h5, p-ch3c6h4, n-ch3)ch2)3, c6h5-ch2 and lewis bases cl¯, br¯, and i¯, were measured in 50% v/v ethanol-water solvent spectrophotometrically. the average equilibrium constant values for the systems studied shows the following acceptor trend of tin(iv) in the triorganotin chlorides: p-tolyl > ...
The equilibrium constant of adduct formation between some triorganotin chloride of the type R3SnCl (R=C6H5, p-CH3C6H4, n-CH3)CH2)3, C6H5-CH2 and Lewis bases Cl¯, Br¯, and I¯, were measured in 50% v/v ethanol-water solvent spectrophotometrically. The average equilibrium co...
the present paper deals with criminal issues. for example, legal injunction on the necessity of returning a deposit has a legal nature and legal injunction on the punishment of those who breach the trust has a criminal nature. existing social issues are the basis of classification of some instances into the issue, some of which are based on variation and others on quality. therefore, the motiva...
To shed light on intramolecular charge-transfer phenomena in 1,2,3-triazole-linked materials, a series of 1,2,3-triazole-linked push-pull chromophores were prepared and studied experimentally and computationally. Investigated modifications include variation of donor and/or acceptor strength and linker moiety as well as regioisomers. Photophysical characterization of intramolecular charge-transf...
The quinoid-donor-acceptor (Q-D-A) strategy has recently emerged as a promising approach for constructing high mobility semiconducting polymers. In order to fully explore the potential of this in improving charge transport and elucidating structure-property-performance relationships Q-D-A polymers, series new polymers with different electron acceptor units backbone coplanarity have been synthes...
A Bodipy-based energy transfer cassette with a singlet oxygen reactive linker between the donor and acceptor modules has an interesting emergent property, if the acceptor module is also a photosensitizer. Singlet oxygen produced by the photosensitizer reacts rapidly with the molecule itself to liberate the energy donor, resulting in an enhanced fluorescence emission. The result is a self-report...
The non-alternant aromatic azulene, an isomer of alternant naphthalene, differs from the latter in peculiar properties. large polarization ?-electron system over seven and five rings gives to azulene electrophile property a pronounced tendency donate electrons acceptor, substituted at 1 position. This paper presents cases which transfers suitable acceptor as methylium ions, positive charged het...
In this paper, we present a novel material with the formula of ZrScMo2VO12 for the first time. It was demonstrated that this material exhibits not only excellent negative thermal expansion (NTE) property over a wide temperature range (at least from 150 to 823 K), but also very intense photoluminescence covering the entire visible region. Structure analysis shows that ZrScMo2VO12 has an orthorho...
