Mukkala, Veli Matti published the artcileNew heteroaromatic complexing agents and luminescence of their europium(III) and terbium(III) chelates, Synthetic Route of 14903-78-7, the publication is Helvetica Chimica Acta (1992), 75(5), 1621-32, database is CAplus.
Twelve heteroaromatic complexing agents were prepared with the purpose to develop suitable labels for time-resolved luminescence-based bioaffinity assays. The relative luminescence yields, excitation maximum, and emission decay constants of their Eu(III) and Tb(III) chelates were determined 2,2′,2”,2”’-[(2,2′-Bipyridine-6,6′-diyl)bis(methylenenitrilo)]tetrakis(acetic acid) and 2,2′,2”,2”’-[(2,2′:6′,2”-terpyridine-6,6”-diyl)bis(methylenenitrilo)]tetrakis(acetic acid) are the most promising agents.
Helvetica Chimica Acta published new progress about 14903-78-7. 14903-78-7 belongs to naphthyridine, auxiliary class 6.6_Aromatics,Naphthyridines, name is 2,7-Dimethyl-1,8-naphthyridine, and the molecular formula is C10H10N2, Synthetic Route of 14903-78-7.
