perylene Chem.|ˈpɛrɪliːn|
[ad. G. perylen (R. Scholl et al. 1910, in Ber. d. Deut. Chem. Ges. XLIII. 2202), f. per(i-di-naphth)ylen, f. peri- peri- (used in a spec. chemical sense) + di- di-2 + naphthylen naphthalene.]
A yellow, crystalline hydrocarbon, C20H12, consisting of five fused aromatic rings, which occurs in coal tar and from which certain organic pigments are derived.
1910Jrnl. Chem. Soc. XCVIII. i. 616 To establish the constitution as a peri-derivative, 1:8-naphthalenediamine was converted into the azimide, this into 8-iodo-α-naphthylamine, and further into 1:8-di-iodonaphthalene, which last when heated with copper powder yielded..peri⁓dinaphthalene, which it is proposed to term perylene. 1946Nature 10 Aug. 209/2 It has also been found that the position and number of fluorescence bands of anthracene, perylene, phenanthrene and naphthacene in benzene are independent of the wave-length of the exciting radiation. 1966New Scientist 29 Dec. 735/3 An electron donor such as perylene (which consists of a series of fused benzene rings) is combined with an electron acceptor such as iodine. 1974Environmental Sci. IX. 352/2 A one-year study of the amount of..benzo(a)pyrene, benzo(k)fluoranthrene, and perylene, was carried out for the particulate matter collected at the York [Ontario] sampling station. |
