AbstractA new class of chiral conjugated materials, ''propeller'' polymers, have been designed and synthesized. By using the transition metal catalyzed cross-coupling reactions including the coupling of terminal alkynes with aryl halides and the Suzuki reaction, chiral binaphthyl monomers are reacted with o-phenylene and m-phenylene halides to construct the ''propeller'' polymers. Due to the chirality of the binaphthyl units and the rigidity of the conjugated system, the dipole units in these novel materials are expected to form a novel propeller-like three-dimensional configuration. Molecular weights of these polymers are analyzed by gel permeation chromatography and laser light scattering. The structures of these polymers are studied by using NMR, UV, IR, CD, and fluorescence spectroscopic methods. The repeat units of these materials are synthesized which provide further evidence for the structure of the polymers. The thermal properties of these polymers are studied by using thermal gravimetric analysis as well as differential scanning calorimetry.
