Özet

The observation of triplet--triplet absorption and emissions of salicylidene-m-bromo-aniline is complicated by possible colored isomer formation during the optical pumping. The short-lived (singlet--singlet) and long-lived (triplet--triplet) absorption spectra were recorded photographically by microsecond flash and nanosecond laser flash photolysis techniques. Salicylidene--aniline complexes were purified by repeated recrystallization until further recrystallization produced no further changes for X-ray diffraction pattern and optical absorption emission properties. B-type delayed fluorescence, T-T absorption, color isomer absorption, and T-T emissions of this compound were recorded for the first time.
