Abstract
The photophysical behaviour of 2-(2′-hydroxyphenyl)perimidine (6), which possesses a strong intramolecular hydrogen bond is evidenced as due to the non-transferred enol form. This compound is highly stable to light, with a photodegradative quantum yield in degassed cyclohexane of 7 × 10 −6, suggesting that the involvement of a lightinduced excited state intramolecular proton transfer (ESIPT) process in which the phenolic proton is transferred from the enol form to the neighbouring nitrogen atom is less important for conferring photostability than has hitherto been supposed for such type of systems.
