In the UV spectra of hydroxydecahydryacridinediones (1) there is long-wave absorption band
(384 - 406 nm), which maximum off
set in the region of 483 - 509 nm when added to a solution of
the base, which defi
nes the possibility of the use of these compounds as indicators base media It
is obvious that the painted is the main form of (II), formed as a result of the tear-off
of a proton
from the acidic form (I).
