Synthesis and optoelectronic properties of janus -dendrimer-type multivalent donor-acceptor systems

A convergent, multistep protocol was employed for the synthesis of a Janus-type multivalent donor-acceptor system. The synthetic approach is based on a Sonogashira cross-coupling of two differently ferrocene-(Fc) substituted dendrons and a final sixfold [

An effective, orthogonal deprotection strategy for differentially functionalized, linear and Y-shaped oligo phenylene ethynylenes

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

Synthesis of a Hexagonal Nanosized Macrocyclic Fluorophore with Integrated Endotopic Terpyridine Metal-Chelation Sites

A rigid nanosized hexagonal phenylethynyl cyclophane 5 has been prepared, which incorporates two 2,2′:6′,2″-terpyridines as integral structural units, for the purpose of binding metal ions. Macrocycle 5 was obtained by a 14-step synthesis in an overall yield of 11%, and was characterised by spectroscopic techniques. The efficiency and ease of all transformations, and the relatively enhanced yield of the final macrocyclisation suggests that the entire synthetic pathway should be amenable to scale-up. Cyclophane 5 possesses four bulky triisopropylsilyl(TIPS) -protected ethyne substituents which serve a dual role. Firstly, they solubilise the structure thereby facilitating purification and subsequent handling. Secondly, they enable post-synthetic modification in which additional functionality may be attached to the periphery of the ring. Significantly, 5 was found to be a fluorescent chromophore, and may therefore potentially function as a new sensory platform for the detection of metal ions and H-bond donating biological substrates. The structurally well-defined nanosized morphology of 5, coupled with its interesting spectroscopic properties, supports the expectation that 5 and related architectures will attain a wealth of future applications within the developing fields of nanochemistry and nanoscience.
