Strapping a benzaldehyde-appended 2,2′-bis-dipyrrin Zn(ii) double-stranded helicate using imine bond formation†
Abstract
A novel linear binuclear Zn(II)/2,2′-bis-dipyrrin double-stranded helicate bearing peripheral p-benzaldehyde moieties has been strapped by formation of imine bonds upon reaction with m-xylylenediamine and characterized by 1H- and 13C-NMR spectroscopy, UV-Visible spectroscopy and high-resolution mass spectrometry.
