A novel series of ditopic ligands bearing two 2,2′:6′,2″-terpyridine or two 4′-phenyl-2,2′:6′,2″-terpyridine subunits and an ethynyl (3a and 3b) or a diethynyl (4a and 4b) bridge has been synthesised from 4′-ethynyl-2,2′ : 6′,2″-terpyridine (1d) and 4′-(4-ethynylphenyl)-2,2′:6′,2″-terpyridine (2c) by coupling with the corresponding triflate- or bromo-substituted substrates, or by self-coupling of the
一系列新的对位配体,带有两个2,2':6',2''-吡啶或两个4'-苯基-2,2':6',2''-吡啶吡啶和一个乙炔基(3a和3b)或一个二乙炔基(4a和4b)桥是由4'-乙炔基-2,2':6',2 ''-吡啶(1d)和4'-(4-乙炔基苯基)-2,2':6',2合成的通过与相应的三氟甲磺酸酯或溴取代的底物偶联,或分别通过乙炔基取代的前体进行自偶联,使″-叔吡啶(2c)。它们形成刚性棒状的同核和异三核钌(II)和铁(II)配合物。
