Abstract

Abstract: A series of coordination‐driven, heteroleptic self‐assembled, bowtie‐shaped bis‐macrocycles were designed and constructed by combining tetrakis(terpyridinyl)thianthrene and bis‐terpyridine, 60°‐directed, Ru 2+ dimers. The resulting complexes were characterized by NMR spectroscopy and ESI‐MS coupled with travelling wave ion mobility spectrometry (ESI‐TWIM‐MS) experiments. The desired bis‐macrocycles were obtained in quantitative yields through the use of long alkyl‐chain substituents, in contrast to the lower yields obtained for smaller alkyl moieties. Abstract : Bis‐macrocycles are obtained in quantitative yields through the use long alkyl‐chain substituents; the improved yields over those with smaller alkyl moieties emphasize the importance of a hydrophobic effect in self‐assembly. The resulting complexes are characterized by NMR spectroscopy and ESI‐MS coupled with travelling wave ion mobility spectrometry (ESI‐TWIM‐MS).
