Molecules for intramolecular recognition. 2. Synthesis and structures of dinaphthyl- and arylnaphthylethynes.
摘要:
Three new tetrasubstituted diaryl alkynes have been prepared via palladium-catalyzed coupling of aromatic alkynes with aryl iodides. These molecules show strong absorption and fluorescence. Single crystal X-ray analysis reveals that the rings are on parallel planes.
