  Palladium-catalyzed cross-coupling between 3,4-dialkoxyphenylboronic acids (1a–d) and 2,3,6,7,10,11-hexabromotriphenylene (2) provided 2,3,6,7,10,11-hexakis[3,4-bis(alkoxy)phenyl]triphenylenes, C18H6[C6H3(OCnH2n + 1)2]6 where n = 6, 8, 10, and 12 (3a–d). Cyclodehydrogenation of the aryl-substituted triphenylenes 3a–d using ferric chloride oxidation followed by methanol reduction produced 6,6′,6″,7,7′,7″,10,10′,10″,11,11′,11″-dodecaalkoxy-2,3′:3,2″:2′,3″-tris(triphenylenylene)s, C54H18(OCnH2n + 1)12 where n = 6, 8, 10, and 12 (4a–d). The mesomorphic properties of the compounds 3a–d and 4a–d were investigated by differential scanning calorimetry (DSC) measurements, polarizing microscopy, and wide angle X-ray diffraction (WAXD). The triphenylenes 3a–d exhibited a columnar mesophase in the range of 111–126, 85–104, 74–103, and 47–101 °C, respectively. Upon oxidation of the moiety, the columnar mesophases shift to higher temperatures and exist in a much broader range of temperatures: for the tris(triphenylenylene)s 4a–d, they have been observed in the range of 180–430, 150–370, 120–322, and 104–306 °C, respectively. Finally, the self-assembly at the interface between a solution of 4c and a graphite substrate has been studied by scanning tunneling microscopy. Molecularly resolved imaging revealed a highly ordered monolayer exhibiting a two-dimensional hexagonal lattice.

  在钯催化下，3,4-二烷氧基苯硼酸（1a-d）与 2,3,6,7,10,11-六溴三亚苯（2）发生交叉偶联，生成 2,3,6,7,10,11-六[3,4-双（烷氧基）苯基]三亚苯，C18H6[C6H3(OCnH2n + 1)2]6，其中 n = 6、8、10 和 12（3a-d）。先用三氯化铁氧化，再用甲醇还原，使芳基取代的三亚苯基 3a-d 环氢化，生成了 6,6′,6″,7,7′,7″,10,10′,10″,11,11′,11″-十二烷氧基-2,3′：3,2″:2′,3″-三(三亚苯)s，C54H18(OCnH2n + 1)12，其中 n = 6、8、10 和 12 (4a-d)。通过差示扫描量热法（DSC）测量、偏光显微镜和广角 X 射线衍射（WAXD）研究了 3a-d 和 4a-d 化合物的介观性质。三亚苯基 3a-d 分别在 111-126、85-104、74-103 和 47-101 ℃ 范围内呈现柱状介相。当分子被氧化时，柱状介相会转移到更高的温度，并在更宽的温度范围内存在：三（三亚苯）4a-d 的柱状介相分别在 180-430、150-370、120-322 和 104-306 ℃ 范围内观察到。最后，我们利用扫描隧道显微镜研究了 4c 溶液与石墨基底之间界面的自组装。分子分辨成像显示出一个高度有序的单层，呈现出二维六边形晶格。

  The synthesis, structural and mesomorphic properties of five tetrabenzopentaphene derivatives are presented. All the compounds exhibit columnar mesophases which have been characterized by optical microscopy, differential scanning calorimetry and X-ray diffraction. The thermogravimetric analysis of the ester derivatives reveals that they suffer a decomposition process to the anhydride derivative at temperatures above 200 °C. The influence of the length of the terminal alkyl chains on the mesomorphic behaviour of the compounds has been studied. The structural characterization of the compounds has been completed with the study of their aggregation in solution by means of NMR. The fluorescent properties of the compounds are reported as well as a preliminary study of the photoconductivity of one of them.

• Synthesis of Extended Triphenylenes by Palladium-Catalyzed [2+2+2] Cycloaddition of Triphenylynes

  The synthesis of ortho-(trimethylsilyl)triphenylenyl triflates 7 is described. Fluoride-induced decomposition of these triflates leads to the generation of didehydrotriphenylenes (triphenylynes) 6. These arynes undergo [4+2] cycloadditions with dienes to afford the corresponding Diels-Alder adducts or palladium-catalyzed formal [2+2+2] cycloadditions to afford extended triphenylenes.
