Abstract: In this thesis, a series of benzene dicarboxylic acid analogues and benzene tricarboxylic acid analogues have been prepared and characterized as building blocks for self-assembly in the solid state. The diacid compounds in the presence and absence of bipyridine bases exhibit wave-like patterns. Overall wave-like topology of the crystal lattice is determined by the spacer group of diacid molecules. The structure of trimesic acid (TMA) complex with 1,3,5-trihydroxybenzene (THB) shows a close packed, distorted honeycomb hexamer, quite different from that of normal TMA patterns. When TMA forms complex with 4-dodecyloxy-pyridine (C12Py), a quite similar structure as 5-alkoxyisophthalic acid was formed. Cyanuric acid, with similar function group orientation as TMA, exhibits ribbon-like structure when cocrytallized with 4,4a??-dithiodipyridine.
