Biacridyl und die sich von ihm ableitenden Radikale und Leuchtsalze, die Luzigenine

Chemiluminescence Induced by Operation of Iron-Flavoproteins*

“…scribed . iV-methyl acridone, prepared according to Bergmann and Blum-Bergmann (1930), was converted to DBA0 and DBA + + as described by Decker and Petsch (1935). The DBA + + thus obtained had a millimolar extinction coefficient of 8.7 at 430 µ and of 34.0 at 368 µ.…”

Polyarenes II

“…One of the most promising modified fullerene prepared so far is the diphenylmethanofullerene (DPM12, 56) prepared by Martín et al [237] endowed with two alkyl chains which improve dramatically the solubility of the acceptor in the blend to reach efficiencies in the region of 3% (Fig. 31).…”

“…Recently it was shown that the conformation of the fluorenylidene-xanthene 39 may be switched from folded (yellow) to twisted (purple) by encapsulation in a suitable cavity [77]. (27), was considered to be the most powerful of all synthetic chemiluminescent substances [237][238][239].…”

Reactions of Lucigenin in protic solvents in the presence of amines

“…Yield 208-282 mg (54-73 YO); m.p. 385°C [3]. This was identified as DBA 2 by comparison of the NMR spectral data with those of an authentic sample; literature [17].…”
