Zusammenfassung

The quantum yields and kinetics of the photodecoloration of five representatives of an inversely photochromic class of compounds, reacting to give spiro compounds related to the indolinospiropyrans by replacement of the chromene part of the molecule by an imidazodihydroquinoline fragment, were investigated by stationary illumination and nanosecond time-resolved laser flash spectroscopy. In particular, the role of the ground state of the open-chain cis conformer as an intermediate in spiro-bond formation (photodecoloration) and opening (thermocoloration) was quantitatively assessed.
