Tahara, Hironobu; Yonemura, Hiroaki; Harada, Satoko; Nakashima, Akio; Yamada, Sunao published an article in 2012, the title of the article was Photoinduced electron-transfer reactions and magnetic field effects on the decay rates of a photogenerated biradical from zinc porphyrin-viologen linked compounds in an ionic liquid.COA of Formula: C16H22Br2N2 And the article contains the following content:
Fluorescence and transient absorption spectra of zinc-porphyrin (ZnP)-viologen linked compounds with various methylene groups indicate that intramol. electron-transfer from the singlet or triplet excited state of ZnP to viologen occurred and a biradical was generated in the ionic liquid (1-butyl-3-methylimidazolium tetrafluoroborate) at various temperatures (283-343 K). The decay rate constants of the biradical decreased in 0-0.2∼0.5 T and became constant in 0.2∼0.5-1 T. Unique effects of temperature and methylene chain length on electron-transfer and magnetic field effects were observed and are probably due to the properties of the ionic liquid as compared with benzonitrile. The experimental process involved the reaction of 1,1′-Dipropyl-[4,4′-bipyridine]-1,1′-diium bromide(cas: 52243-87-5).COA of Formula: C16H22Br2N2
