Nanoscale Spherical Architectures Fabricated by Metal Coordination of Multiple Dipyrrin Moieties

摘要

Metal ion coordination enables organic ligands to form versatile discrete or infinite architectures,such as wire structures and nano-space materials,with potential applications in catalysis,optics,and biosensing.Recently,nanoscale morphologies based on coordination polymers have been reported to exist as spherical and fibrous structures.Of the coordinating ligands,dipyrrins(dipyrromethenes),consisting of two pyrroles with an sp~2-meso position,are essential pi-conjugated bidentate monoanionic ligands for metal ions in natural and artificial systems
