description

Es wird uber die Synthese von methylsubstituierten, ein- und zweifach m-gewinkelten Oligophenylenen bis zum Kondensationsgrad 14 berichtet. Durch Anwendung chromatographischer Methoden konnten die Verbindungen rein isoliert werden. Gewinkelte Oligophenylene besitzen bei vergleichbarer Struktur einen niedrigeren Schmelzpunkt und eine bessere Loslichkeit als p-Oligophenylene. The synthesis of methyl-substituted oligophenylenes with one or two meta-bonds up to a polymerisation degree of 14 is described. By application of chromatographic methods these compounds could be isolated free of impurities and homolog products. Angled oligophenylenes possess a lower melting point and a higher solubility than comparable p-oligophenylenes.
