Abstract
Two deazabipyridyls, 2-(2-hydroxyphenyl)pyridin-3-ol 1 and 2-(2-pyridy l)phenol 2, are the objects of X-ray and spectroscopic studies. Their syntheses, crystal structures and photophysics in comparison with [2,2 '-bipyridyl]-3,3'-diol and [2,2'-bipyridyl]-3-ol 3 are described. The influence of the molecular structure on the efficiency of the proton-t ransfer reaction in the S1 state is discussed. The experimental data a re compared with semiempirical quantum chemical calculations.
