英文摘要	Conjugated rod-coil molecules, incorporating flexible and rigid blocks, have a strong affinity to self-organize into various supramolecular nanostructures in the bulk state. In this study, we report synthesized oligomers containing cruciform 9,10-bis(arylethynyl)anthracene units and characterized their self-assembly behavior. The molecular structures were characterized with H-1, C-13 NMR, and matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectroscopy. An investigation of the supramolecular nanostructures of these molecules using differential scanning calorimetry, thermal polarized optical microscopy, and small-angle X-ray scattering revealed that the rod length of coil-rod-coil molecules with identical rod to coil volume ratios dramatically influences self-assembly behavior in the bulk state. Molecules 2 and 3 with relatively longer rod lengths self-assemble into lamellar structures in the solid state, whereas, molecules I and 4 self-assemble into two-dimensional (2-D) oblique columnar structures in the liquid crystalline phase, in addition, on heating, molecule 1 transforms from the oblique columnar phase to the nematic phase.
