Placido Mineo, Fabiola Spitaleri and Emilio Scamporrino A water soluble macromolecular nanobox having porphyrinic walls as a large host for giant guests Journal of Polymer Science Part A: Polymer Chemistry 51
This work describes a simple and fast procedure to synthesize a water soluble 3D macromolecular box, having four porphyrin units as walls, and its Cobalt derivative. Their chemical and spectroscopic characterization was performed by means of MALDI-TOF-MS, NMR, CD, and UV–vis spectroscopy. The molecular structure of these systems suggests their use as nanoscopic molecular boxes, able to incorporate giant molecular species. Preliminary experiments about the host/guest complex formation between these cycles and Gramicidin S have been here discussed.
