چکیده
A novel phosphine-based tetragonal cage has been assembled from a tetraphenylethylene (TPE)-based tetraphosphine and Ag(+) ions. The cage structure is maintained both in solutions and in the solid state. emits strong fluorescence not only in dilute solutions but also in aggregated states. The turn-on fluorescence of TPE-P4 in dilute solutions is attributed to the formation of . shows potential as a fluorescent sensor towards anions and olefin compounds, which arises from binding of the guest anions/olefin compounds by its labile silver centres.

Luminescent Silver(I) and Copper(I) Systems Containing Pyridyl Phosphine Bridges
Luminescent silver(I) and copper(I) complexes containing pyridylphosphine ligands have been synthesized and structurally characterized by single crystal X-ray diffraction methods. The reaction of Ag(OTf) (OTf = trifluoromethanesulfonate) with 2-pyridyldiphenylphosphine in different molar ratios gives the species [Ag2(OTf)2(μ-PPh2py)2] (1), [Ag(PPh2py)2]OTf (2), [Ag(PPh2py)3]OTf (3), and [Ag2(PP...

Coordination-driven self-assembly of discrete nanosized molecular cages has become one of the most active areas of supramolecular chemistry.1 Over the past decade, extensive studies have been made on discrete molecular assemblies MxLy with various values of x and y.2 Among these metal-ligand clusters, the assembly of M2L4 tetragonal cage remains quite rare, although a few such d-block metal sup...
متن کاملSnowman-like silver alkynyl cluster consolidated by templating chloride and peripheral trifluoroacetates.
A novel nonadecanuclear silver double cage was isolated, in which a square antiprism and a pentacapped pentagonal prism templated by a chloride ion share a tetragonal face to form a snowman-like cluster that is held together by bridging alkynyl groups and trifluoroacetates.
متن کاملA luminescent hydrogel based on a new Au(I) complex.
The reaction of the water soluble phosphine 1,3,5-triaza-7-phosphaadamantane (PTA) with [Au(C≡C-C(5)H(4)N)](n) yields the highly luminescent water soluble [(PTA)Au(4-pyridylethynyl)] complex. A detailed analysis of the compound shows the formation of gel structure giving rise to very long fibers, being the first example reported with such a simple structure.
