Divergent Synthesis of Polyphenylene Dendrimers: The Role of Core and Branching Reagents upon Size and Shape
Autor: Günter Lieser, Uwe-Martin Wiesler, Klaus Müllen, Alexander J. Berresheim, Frank Morgenroth
Publikováno v: Macromolecules. 34:187-199
Monodisperse polyphenylene dendrimers up to the fourth generation were synthesized using a divergent growth protocol. By varying the core, dendrimers with dumbbell-, tetrahedral- and propeller-like structures were synthesized. Because of the high-den

2,5-diphenyl-3,4-bis[p-(phenylethynyl)phenyl]cyclopentadienone and product of its Diels-Alder homocondensation

A new monomer of the ABA type, 2,5-diphenyl-3,4-bis[p-(phenylethynyl)phenyl]-cyclopentadienone, was synthesized. The Diels-Alder homocondensation of the monomer resulted in a highly branched polyphenylene (Mw=160000), readily soluble in organic solve

Dendritic and hyperbranched polyphenylenes via a simple Diels-Alder route
Autor: Klaus Müllen, Frank Morgenroth
Publikováno v: Tetrahedron. 53:15349-15366
A Diels-Alder route to dendritic and hyperbranched polyphenylenes, based on hexa(penta)phenylbenzene units, is described. Using ethynyl-, propynyl- and phenylethynyl-substituted tetraphenylcyclopentadienones 1c−e, hyperbranched polymers with molecu

The benzene ring as modulus: synthesis and supramolecular ordering of novel conjugated polymers
Autor: Thomas Soczka-Guth, Ullrich Scherf, Frank Morgenroth, Klaus Müllen, Gerrit Klärner, Maren Müller
Publikováno v: Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences. 355:715-726
Conjugated polymers possess attractive electronic and optical properties which also qualify them as active components of devices. Many conjugated polymers are made up of benzenoid building blocks. The functionalization of benzene rings is therefore a

Conjugated oligomers and polymers —new routes, new structures
Autor: Gerrit Klärner, Frank Morgenroth, Klaus Müllen, M. Wehmeier, Markus Müller, Thomas Soczka-Guth
Publikováno v: Synthetic Metals. 84:297-301
We discuss new conjugated materials which are formally derived from classical polymers such as PPP, PPV and PAni. In this context strategies for the systematic separation of dipoles in PPV's, the planarization of PPP-type structures and the design of

Nanosized polyphenylene dendrimers based upon pentaphenylbenzene units
Autor: Frank Morgenroth, Christian Kübel, Klaus Müllen
Publikováno v: Journal of Materials Chemistry. 7:1207-1211
A facile divergent synthesis of monodisperse polyphenylene dendrimers having diameters of 21–55 A is presented. These nanoparticles have been preparedvia a [2+4]cycloaddition–deprotection sequence using an excess of tetraphenylcyclopentadienone 1
