Краткий осмотр (реферат): The migration of excitation energy of a number of psoralen compounds has been studied.
For this, the methods of induced absorption spectroscopy, stationary electron
spectroscopy, fluorescence and phosphorescence, as well as quantum chemistry
were used. A comparative photostability of psoralen was achieved by exposure to a
XeCl excilamp irradiation (emission wavelength λem 308 nm) with parameters Δλ
5–10 nm, Wpeak 18mW/cm2, p 8.1 J/cm3, f 200 kHz, pulse duration 1 μs. It was
found that the singlet-triplet transition played a major role in the migration of excitation
energy into triplet states. Among all tested compounds, substances with an OCH3-group
in the structure have the strongest effect on the spectral-luminescent characteristics2021-11-04T00:00:00Z
