Abstract: In this thesis, two new supramolecular complexes were designed and synthesized. The molecular rectangles possess large cavities. The first molecular rectangle, [Au4(PAnP)2(DPE)2](OTf)4, has a cavity of 8.108 x 19.093 &Aring. The second molecular rectangle, [Au4(PAnP)2(BPE)2](OTf)4, has a cavity of 9.197 x 18.662 &Aring. The electronic absorption and emission spectroscopy of both rectangles have also been studied. Both molecular rectangles are capable of host-guest interactions with aromatic guests such as 9-bromoanthrancene, naphthalene, phenanthrene and pyrene. The emissions of the AuI rectangles were quenched upon guest binding. Another AuI molecular rectangle, [Au4(PAnP)2(bipy)2](OTf)4, which was previously synthesized by our laboratory was used to form a self-organized monolayer on several different substrates such as highly oriented pyrolytic graphite (HOPG), undoped nanocrystalline diamond (u-NCD) and gold. The molecular layer was characterized by several surface techniques such as X-ray photoelectron spectroscopy, ellipsometry, surface fluorescence and scanning tunneling microscopy.
