Electron polarization of pyridinyl radicals generated from the photosensitized dissociation of the dimers was studied. Addition of triplet sensitizer to the dimer solution induced drastic change in the CIDEP spectrum. Examinations of the dependence of spectral change on the T1 state energy level and the spin alignment in the T1 sublevels of sensitizers lead to the conclusion that energy transfer between the pyridinyl dimer and the sensitizer occurred and that the spin polarization was conserved during the process. From a series of triplet donors, nonphosphorescent T1 states of two types of pyridinyl dimers were estimated to be 2.43 eV for the 2,2′-dimer of 1-methyl-4-tert-butylpyridinyl and 2.65 eV for the 4,4′-dimer of 1-methylpyridinyl. In the experiment, the researchers used many compounds, for example, Pyrido[2,3-b]pyrazine (cas: 322-46-3Related Products of 322-46-3).
Pyrido[2,3-b]pyrazine (cas: 322-46-3) belongs to pyrazine derivatives. Pyrazine heterocycles and their benzo derivatives possess many interesting properties, including chemical reactivity profiles, and have diverse applications in total synthesis, medicine, chemical biology, materials, dyes, and imaging.
