The precise construction of the high-order mechanically interlocked molecules (MIMs) with well-defined topological arrangements of multiple mechanically interlocked units has been a great challenge. Herein, we present the first successful preparation of a

We present the successful construction of a new family of organometallic rotaxane-terminated dendrimers using neutral platinum-acetylides as the main scaffold. The fourth generation dendrimer has 24 rotaxane moieties on the surface termini in a monodisper
Modular syntheses of star-shaped pyridine, bipyridine, and terpyridine derivatives by employing sonogashira reactions

A simple and flexible synthesis for a series of star-shaped pyridine, bipyridine, and terpyridine derivatives is reported by using a modular approach that combines the use of a ligand, spacer, and core unit. A fairly efficient method to prepare 4′-nonafloxy-functionalized terpyridine derivatives is described. The building blocks that contain the functionalized pyridine, bipyridine, or terpyridine derivatives were linked to different C3-symmetrical core units. In most cases, Sonogashira reactions were employed in the crucial final steps of the synthesis. A star-shaped dodecafluorinated compound was also prepared in a straightforward fashion. A simple procedure for the preparation of partially silylated 1,3,5-triethynylbenzene derivatives is presented, which provides an approach to C2-symmetrical star-shaped compounds that have only one terpyridine and two terphenyl units as "dummy" ligands. The absorption and emission spectra of the fully conjugated C3-symmetrical pyridine derivatives were systematically investigated, and fairly large Stokes shifts were observed.

Herein we report the synthesis of two luminescent branched tetranuclear alkynylplatinum(II) complexes {[Pt(tBu3-tpy)]2[Ar(CC) 4][Pt(tBu3-tpy)]}2(PF6)4 (I and II; tBu3-
An effective, orthogonal deprotection strategy for differentially functionalized, linear and Y-shaped oligo phenylene ethynylenes
Chandra, Kusum L.,Zhang, Sheng,Gorman, Christopher B.
, p. 7120 - 7132 (2008/02/07)
Several methodologies for the selective deprotection acetylenes have been reported previously. However, as is shown here, they are often not reliable or convenient. Here, an approach is reported that is efficient and general. Use of this approach to synth
Investigations of Electronic Energy Transfer Dynamics in Multiporphyrin Arrays
Brodard, Pierre,Matzinger, Stephan,Vauthey, Eric,Mongin, Olivier,Papamicael, Cyril,Gossauer, Albert
, p. 5858 - 5870 (2007/10/03)
A study of the dynamics of electronic energy transfer (EET) in arrays containing three, four, and six tetraphenylporphine units connected with phenylethynyl spacers is reported. For arrays containing the same chromophores, the EET rate constant was determ
