Metal-Organic Cubane Cage with Trimethylplatinum(IV) Vertices.

Herein we describe the synthesis and characterization of the first platinum(IV) metal-organic cage [(MePt)(byp)](OTf) (), in which the organometallic moieties trimethylplatinum(IV) (PtMe) occupied the corners of a cubane structure and 4,4'-bipyridine ligands used as linkers. The first-principles density functional theory calculations showed that the highest occupied molecular orbitals were localized on the PtMe moieties, while the lowest unoccupied molecular orbitals were distributed on the organic linkers.

Bis-N-Heterocyclic Carbene Complexes of Coinage Metals Containing Four Naphthalimide Units: A Structure-Emission Properties Relationship Study.

Naphthalimide derivatives provide highly versatile self-assembled systems and aggregated forms with fascinating emission properties that make them potential candidates for many applications such as bioimaging and sensing. Although various aggregated species of naphthalimide derivatives have been well documented, little is known about the correlation between their structure and photophysical properties. Here the preparation of a series of tetrameric naphthalimide molecules in which naphthalimide units are linked by bis-N-heterocyclic carbene complexes of coinage metals is described.
