Abstract-5-Arylmethyl-2,4,6-(1H,3H,5H)pyrimidinetriones and 12-aryl-8,12-dihydrobenzo[f]pyrimido-
[4,5-b]quinoline-9,11-(7H,10H)diones were synthesized, and their spectral-luminescence and nonlinear-optical
properties were examined.
Organic luminophores containing a carbonyl group,
either in the open chain or incorporated into the cyclic
system, are of great practical significance. These com-
pounds include, in particular, arylmethylpyrimidine-
triones, both known and new, and pyrimidoquinoline-
diones prepared by the scheme
Vd, Vf, Vh3Vl
where R = N(CH
(c), 2,4-di-OMe (d), 3,4-di-OMe (e), 3-OEt-4-OH (f),
3-OMe-4-OCOEt (g), 3-OMe-4-OCO(CH
2,4-di-Cl (i), 3-OMe-4-OH (j), 3-OMe-4-OCOC
(k), and 2-F-6-Cl (l).
Refluxing equimolar amounts of appropriate benz-
aldehyde Ia!Ih and 2,4,6-(1H,3H,5H)pyrimidine-
trione (barbituric acid) II in an alcohol solution
resulted in selective formation of 5-arylmethyl-2,4,6-
