We developed a concise synthetic method for benzotrifurans and benzotripyrroles from 1,3,5-triethynyl-2,4,6-trifluorobenzenes by one-pot reactions in good to excellent yield. By investigating 2-D and 3-D structures of a variety of benzotrifuran and benzotripyrrole derivatives using scanning tunneling microscopy (STM) and single-crystal X-ray diffraction techniques, we found both similarities and dissimilarities. We also found that diverse molecular 3-D orientations were derived in their single crystals according to substituents on the molecules and that the emission properties in the solid state are dependent on their packing manners.

The synthesis of a series of octopolar 1,3,5-tris(ethynylphenyl)benzenes via Sonogashira coupling is described, varying the substituents on both the central benzene core as well as the acetylenic periphery. In particular, systems bearing an electron-rich
New persubstituted 1,3,5-trisethynyl benzenes via Sonogashira coupling

, p. 1147 - 1149 (2007/10/03)
Starting from 1,3,5-trifluoro-2,4,6-triiodobenzene, selective Sonogashira coupling gave trisalkynylbenzenes, which can be further functionalized making use of the reactive fluorine substituents on the benzene core. Additionally, an unexpected conversion o
