Reflectance Fluorescence Spectra of Aromatic Compounds in Potassium Bromide Pellets.

“…Preparation of Periflanthene [Diindeno(l,2,3-cd:l',2',3'-lm)perylene ]. This hydrocarbon was prepared by selfcondensation of fluoranthene with sodium amide in xylene (7). The compound was purified by vacuum sublimation to give red crystals (m. p. > 360°C .…”

Perylene, Oligorylenes, and Aza-Analogs

“…Seeing similarities between the UV–vis spectrum of Clar’s quaterrylene and the known diindenoperylene 38 (Scheme ), Zinke attempted to repeat Clar’s quaterrylene synthesis in order to prove that Clar had prepared a known compound, which was misattributed the structure to an oligorylene. , Zinke proposed that the solvent of Clar’s reaction, benzene, had reacted with perylene to form diindenoperylene 38 . He confirmed this by treating dibromoperylene 39 with benzene and AlCl 3 to produce diindenoperylene 38 .…”

Nanoscale Order and Structure in Organic Materials: Diindenoperylene on Gold as a Model System

“…Diindenoperylene (DIP, C 32 H 16 , Figure 1) is a perylene-based molecule known since the beginning of the last century when it was synthesized in 1934. 1 The interest in this molecule has recently enjoyed a renaissance because of the properties of its thin films that may have applications in organic electronics.…”
