Abstract 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 ...
