New carboxy-functionalized terpyridines as precursors for zwitterionic ruthenium complexes for polymer-based solar cells
摘要:
New carboxy-terpyridines selectively functionalized at the 4-, 4'- and 4"-positions were prepared in a three-step procedure with good yields using, the Krohnke reaction followed by saponification. Their complexation with ruthenium led to symmetric and unsymmetric terpyridinyl zwitterionic complexes. (c) 2006 Elsevier Ltd. All rights reserved.
为了扩大双(吡啶)金属连接的效用,对4'-(4-溴苯基)-2,2'进行选择性对称和不对称的4,4''-官能化(-CN,-Me,-CO 2 Me)使用Kröhnke合成法获得了:6',2''-叔吡啶。将最终取代的2,2':6',2''-吡啶及其相应的中间体4a - c进行重结晶,并通过1 H NMR和13 C NMR以及X射线晶体学进行表征;还进行了COZY相关性以允许确定的质子分配。

The construction of a heteronuclear (Ru4Fe2) hexameric metallomacrocycle with methyl- and carbonyl-functionalized bis(terpyridyl) moieties was achieved by a self-assembly of a dinuclear trimer, which was prepared in high yield viaPd(0) coupling of a bis-iodo functionalized dinuclear complex with a terpyridine possessing an acetylene group.
通过甲基和羰基官能化的双(叔吡啶基)部分的异核(Ru 4 Fe 2)六聚金属大环的构建是通过双核三聚体的自组装实现的,该双核三聚体是通过Pd(0)偶联而高产率制备的。一种双碘官能化的双核配合物,其中的吡啶具有一个乙炔基。
