A novel family of bis(terpyridinyl) ligands was designed and constructed by facile Pd-catalyzed coupling reactions. Subsequent terpyridine–transition-metal complexation facilitated self-assembly resulting in a hexagonal, trimeric series of metallomacrocycles. An enhanced solubility of a macrocycle and its bis(terpyridine) precursor possessing elongated, alkyl-branched phenylacetylene spacers was achieved
通过简便的 Pd 催化偶联反应设计并构建了一个新的双(三联吡啶基)配体家族。随后的三联吡啶-过渡金属络合促进了自组装,产生了六边形、三聚体系列的金属大环。通过引入十二烷氧基部分,可以提高大环及其双(三联吡啶)前体的溶解度,该前体具有细长的烷基支化苯乙炔间隔基。金属大环的表征包括 1H、13C NMR、紫外光谱和质谱以及电化学。(© Wiley-VCH Verlag GmbH & Co. KGaA,69451 Weinheim,德国,2008)
