Synthesis, Photophysical Properties, and Ab Initio Calculations of 2-(2-Hydroxy/methoxyphenyl)pyrimidines Substituted by Sterically Hindered Electron-Donating Groups
A series of 2-(2-hydroxyphenyl)pyrimidines bearing sterically hindered electron-donating groups (DMAC, PXZ, PTZ, and NPh2), together with their methoxy precursors, were synthesized and investigated by photophysical studies and ab initio calculations. While the hydroxy derivatives were essentially nonemissive due to e...
