Excited-State Intramolecular Proton Transfer in 2‑(2′- Hydroxyphenyl)pyrimidines:
The development of fluorescence materials with switched on/off emission has attracted great attention owing to the potential pplication of these materials in chemical sensing. In this work, the photophysical properties of a series of original 2-(2′- hydroxyphenyl)pyrimidines were thoroughly studied....

| description |
The development of fluorescence materials with switched on/off emission has attracted great attention owing to the potential pplication of these materials in chemical sensing. In this work, the photophysical properties of a series of original 2-(2′- hydroxyphenyl)pyrimidines were thoroughly studied. The compounds were prepared by following well-established and straightforward methodologies and showed very little or null photoluminescence both in solution and in the solid state. This absence of emission can be explained by a fast proton transfer from the OH group to the nitrogen atoms of the pyrimidine ring to yield an excited tautomer that deactivates through a nonradiative pathway. |
