The synthesis and structural characterization of luminescent di- and tri-nuclear organopalla-dium complexes with rigid conjugated alkynyl-aryl bridges and preliminary experiments on the formation of the first generation metallodendrimer using the trinuclear complex as the backbone were reported.102... 

In addition to the well-known luminescent Re(NAN)(GO)3 moieties, the electrochemically active ferrocenyl groups were employed as building blocks for the construction of polynuclear silver(i) alkynyl complexes. Yip reported the synthesis, structural characterization, and electrochemistry of a tetranuclear complex, [Ag3(dppm)3(C=CFc)(OTf)]OTf 96 (Figure 43), with the Ag3(dppm)3 skeletal unit being capped by a ferrocenylethynyl ligand on one side and an OTP anion on the other, all in a /Z3-771-bonding mode.170... 

The luminescence behavior of a binuclear gold(I) alkynyl complex with a bridging dppf ligand, [(dppf)Au2 C=CC(Me)=CH2)2], was also reported... 

With the more sophisticated dialkynylcalixarenes as ligands, tetranuclear gold alkynyl complexes 8a and 8b (Fig. 13), in which both a- and n-coordinated gold centers are present and exhibit short intramolecular Au Au contacts of 3.1344(8) and 3.2048(8) A, were obtained [104], The complexes were found to be strongly luminescent at 591-616 nm in the solid state, whereas in chloroform solution or 77 K CHCl3-MeOH-EtOH glass... 

Tor modified a 2/-deoxyuridine with an alkynyl moiety at the 5-position of the base, and coupled it to ruthenium(II) and osmium(II) complexes with a 3-bromo-l,10-phenanthroline ligand to produce nucleosides (5) [33]. The ruthenium(II) nucleoside emits at 633 nm with a lifetime of 1.1 ps and a luminescence quantum yield of 0.051 in degassed aqueous solutions, while the osmium(II) analogue shows lower-energy and much weaker emission (A.em = 754 nm, tq = 0.027 ps, (Pcm = 0.0001). Phosphoramidites equipped with these... 

A series of luminescent mercury(II) bis(alkynyl) complexes containing oligothiophenes have been synthesized by Wong via direct merciuation of the corresponding alkynes (see equation S). Most importantly, the optical properties of these species have been found to be easily tuned by modifying the... 

A series of rhenium(I) complexes [Re(CO)3(N-N) ( C=C -R)] containing conjugated alkynyl ligands displayed remarkable luminescence properties. The origin of the...
