Series of Re(I) carbonyls complexes were designed and synthesized to explore the impact of the triimine skeleton and number of methoxy groups attached to aryl substituents on their optoelectronic and thermal properties. The chemical structures of the prepared complexes were confirmed by 1H and 13C NMR spectroscopy, HR-MS, elemental anlsysis, and X-ray measurements. DSC measuremtns showed that they
设计并合成了一系列Re(I)羰基配合物,以探索Triimine骨架以及与芳基取代基相连的甲氧基的数量对其光电和热学性质的影响。制备的配合物的化学结构通过1 H和13 C NMR光谱法,HR-MS,元素无名氏病和X射线测量得到证实。DSC测量表明,它们在198-325℃的范围内熔化。其中一些可形成具有高玻璃化转变温度(158-173°C)的稳定分子玻璃。实验获得的光学性能得到DFT计算的支持。UV-Vis光谱在200-350 nm范围内显示了一系列重叠的吸收带,并且由于分别发生了配体内和电荷转移跃迁,因此在可见光谱范围内的宽带弱得多。所有合成的配合物在溶液中均以粉末形式呈固态发射。此外,当应用于二极管时,它们中的一些具有在外部电压下发光的能力,最大电致发光带位于591-630nm。

(terpy) and substituted derivatives of the form [M(R-terpy)2]2+ display a wide range of redox potentials that correlate well to the Hammett parameter of the terpy substituents. Less is known about the impact of incorporating a phenyl spacer between the functional group responsible for controlling the electron density of terpy and how that translates to metal complexes of the form [M(4′-aryl-terpy)2]2+, where

has been prepared by the reaction of metal complexes bearing pendant phenolic functionalities with complexes containing electrophilic ligands. Specifically, M(tpy)2} motifs (M=Ru or Os; tpy=2,2':6',2''-terpyridine) bearing one or two pendant 3,5-dihydroxyphenyl substituents at the 4-position of the central ring of the tpy have been reacted with the complexes [Ru(tpy)(Xtpy)]2+ (X=Cl or Br) to form new

The compositions of the present invention comprise one or more palladium bound ligands that are covalently bonded to inorganic or organic solid supports. These palladium bound ligands bonded to solid supports can be used for single heterocyclic amine base separation, or can be used to separate nucleotide chain containing specific sequences from other nucleotides or nucleotide chains. In one aspect of the invention, each ligand present is individually complexed to a single Pd(II) ion. If there are from 2 to 4 ligands present in the composition, then each ligand present must be separated from the other ligands by at least 3 atoms, preferably from 3 to 20 carbon atoms or equivalent spacing.
