“…169°C was characterized by 1 H NMR (270 MHz) and IR spectroscopy and again claimed as hexatolane 1. [7] The authors also provided a UV/Vis spectrum of this product, which appears similar but not identical to that published in 1987 by Praefcke. [6,24] In the course of our studies, [1] we performed the Pd 0 -catalysed phenyethynylation of hexahalobenzenes 3 and 4 under the different previously described conditions.…”

A previously overlooked hydrodehalogenation reaction occurring during the multiple Pd0‐catalysed C−C coupling reaction between phenylacetylene and hexaiodo‐ and hexabromobenzene was found to give pentakis(phenylethynyl)benzene (“pentatolane”) as the major product, but no hexakis(phenylethynyl)benzene (“hexatolane”) under conditions previously claimed to yield the latter hydrocarbon. As an alternative to a viable route to hexatolane described in the literature, an independent synthesis of this hydrocarbon through sixfold Sonogashira coupling of hexakis(ethynyl)benzene with iodobenzene has been developed. Some physical and spectroscopic properties of hexatolane and of the hitherto unknown pentatolane have been determined after thorough purification by HPLC. (© Wiley‐VCH Verlag GmbH & Co.

“…Spectroscopic work 41 suggests that a dendrimer-like aggregate with 6-fold symmetry does not exhibit the desired exciton localization, since it is lost through ortho and parasubstitution across a phenyl linkage. The meta substitution of the BA 3 aggregate acts to separate the dendrimeric chain of which it is part into regions with a distinct electronic integrity.…”

Fundamental theory is developed for three-body resonance energy transfer in the condensed phase, involving two donors and a single acceptor. This energy pooling mechanism is responsible for recent experimental observations on trichromophore molecules and other moieties, manifest for example in the photochemistry of organo dyes and rare-earth ion doped crystals. A full quantum electrodynamical (QED) treatment of this pooling is developed and formulated with the aid of a novel diagrammatic method, which proves to have several advantages over Feynman diagram methods. Following derivation of the rate of energy pooling for an isolated group of chromophores, the electronic influences of the medium across which the energy migrates are embedded in the theory and duly discussed. Energetic constraints on the acceptor molecule are elucidated and shown to account for a variety of postulated mechanisms: the geometry of the three-center system is itself shown to exercise considerable control over the dominant mechanism. By extension, the theory is amenable to the study of more complex energy transfer arrangements, such as those observed in dendrimer chemistry and the light-harvesting photochemistry of the photosynthetic unit.
