, p. 1573 - 1579 (2001)
2-Amino-3-pyridinecarboxaldehyde is synthesized in a highly efficient process via ortho-lithiation of 2-(pivaloyl-amino)pyridine and reaction with DMF, followed by acid hydrolysis. Major impurities were identified and were cleanly eliminated through careful choice of base and solvent.

A multifunctional fluorescent chemosensor for Al3+ and Cu 2+ has been developed, which displays a dual-model and on-off fluorescence response upon addition of Al3+ and Cu2+ respectively. The fluorescence signals of the chemosensor can be restored with F- and ethylenediaminetetraacetic acid (EDTA) disodium for Al 3+ and Cu2+, showing that the binding of the chemosensor and Al3+/Cu2+ is chemically reversible. The 'in situ' prepared Al3+ complex (1·Al) showed high selectivity toward F-, which can be applied to distinguish F- from Cl -, Br- and I-. Moreover, the fluorescence emission intensity of the 'in situ' prepared Cu2+ complex (1·Cu) is increased with the addition of Al3+, demonstrating that 1·Cu could be a good off-on Al3+ sensor candidate.

We designed a novel naphthyridine-based supporting ligand involving two silyl coordinating moieties at 2,7-positions, t-BuNBSi, for the synthesis of dinuclear metal complexes. Reaction of a ligand precursor t-BuNBSi(H)2 (1) with Ru3(CO)12 gave a di-μ-hydridodiruthenium(II,II) complex (t-BuNBSi)Ru2(μ-H)2(CO)4 (2). Photoirradiation to 2 resulted in the formation of a diruthenium(I,I) complex (t-BuNBSi)Ru2(CO)6 (3). The SiRuRuSi linkage of 2 takes a zigzag arrangement, whereas that of 3 adopts a roughly linear one.

The invention relates to a silicon-containing organic electroluminescent material and an application thereof as well as a device manufactured by using the silicon-containing organic electroluminescent material. The silicon-containing organic electroluminescent material is a compound which is formed by centering on naphthyridine substituted tetraphenyl-silicon and introducing substituent groups with relatively good electronic transmission performance into benzene rings. The silicon-containing organic electroluminescent material can serve as an electron transport layer of an organic electroluminescent device. The material provided by the invention has relatively good thin-film stability, appropriate energy level and wide application prospect in the organic electroluminescent device, can serve as an electron transport material to be applied to the organic electroluminescent device and is capable of remarkably improving the color purity of blue light devices.
