Dynamic properties of molecular tweezers with a bis(2-hydroxyphenyl) pyrimidine backbone
4,6-Bis(2-hydroxyphenyl)-2-alkylpyrimidines with two anthryl or 9-ethylnylanthryl substituents at the positions para to the OH groups prefer a U-shaped conformation supported by two intramolecular OH...N hydrogen bonds in the solid state and in CDCl3
Tweezers-like aromatic molecules and their luminescent properties depending on the structures
Di(hydroxyphenyl)pyrimidine with two anthryl substituents 1a was synthesized and characterized by X-ray crystallography and NMR spectroscopy. The molecule prefers 'U'-shaped conformation supported by intramolecular O-H?N hydrogen bonds in the solid state
