AbstractWe present a comparison of the assembling behavior of two series discotic molecules, n-alkoxy-substituted stilbenoid compounds (E, E; E)-1,3,5-Tris[2-(3,4,5-trialkoxyphenyl) ethenyl] benzenes (nTEB, n = 12, 14, 16 and 18) and n-alkoxy-substituted triphenylenes, 2,3,6,7,10,11-hexakisalkoxytriphenylenes (HnT, n = 9, 12, 14, 16, 18 and 20), on highly oriented pyrolytic graphite surface using scanning tunneling microscopy. Characteristic two-dimensional self-assembly structures, hexagonal structures and linear array structures, were observed with different alkyl chain length for both series of molecules. While linear lamellae structure prevails for long alkyl substituted species of both series, the hexagonal assembly pattern differs significantly. It was evident that 12TEB develops center-void hexagonal structures and H12T adopts center-filled hexagons. The difference of the assembling structure could be attributed to the steric effect associated with molecular cores. (C) 2003 Elsevier Science B.V. All rights reserved.
