Self-assembled structures
formed from a pyridine-appended zinc
chlorophyll derivative are reported. While the zinc complex forms
cyclic oligomers in chloroform solution, as indicated by 1H NMR studies (including diffusion-ordered spectroscopy), vapor pressure
osmometry, and cold-spray ionization mass spectrometry, it forms double-stranded
helical coordination polymers in the solid state, as revealed by single-crystal
X-ray analysis.
