Smagowicz, J.; Wierzchowski, K. L. published the artcile< The phosphorescence of hindered aminopyrimidines>, Reference of 112-63-0, the main research area is phosphorescence aminopyridimidine; pyrimidine alkyl amino phosphorescence; alkylpyrimidine phosphorescence.
The quantum yields, lifetimes, and polarizations of phosphorescence of 4- and 5-aminopyrimidines and their hindered alkyl derivatives were measured in solvents of different polarity at 90掳K. The model presented for interpretation of these data allows determining the matrix elements of spin-orbit coupling between the emitting singlet and triplet states. These elements are 0.2-0.8 cm-1 in aminopyrimidines and increase as the amino group becomes more twisted relative to the ring. Spin-orbit coupling of higher 1(n,蟺*) states with emitting triplets is 鈭?0 times stronger than that of the lowest 1(l,a蟺*).
