项目摘要

1.A series of naphthalene derivatives in which oligothiophene units were cofacially stacked through peri positions, were synthesized, and their physico-chemical properties have been investigated with an eye to develop new electronic molecular devices, which, for example, reveled that the cofacial oligothiophene units of these molecules interact with each other to lower their CV oxidation potentials.2.A one-pot synthesis of 3,6-dimethylthieno [3,2-b] thiophene and 3,6-dimethylselenolo [3,2-b] selenophene was developed. Starting from these now easily accessible monomers, their dimers, trimers, and tetramers, which are an unprecedented type of oligomers, were synthesized. Physico-chemical properties of these oligomers have been also investigated with expectation of developing new molecular devices and conductive polymers.3.A one-pot synthesis of tetraarylthiophenes and tetraarylselenophenes, using diaryl acetylenes and elemental sulfur or selenium as the starting materials, was developed. Application of this synthesis enabled the preparation of a star-burst type of oligothiophenes and oligoselenophenes.4.A series of heterothiophenetriptycenes, chemisty of which had never been explored, were synthesized and their physical and chemical properties were investigated. Metal complexes of some of these compounds were also synthesized satisfactorily.5.A new synthesis of a unique class of inner salt, bis (dialkylamino) carbeniumdithiocarboxylates, was developed and their structures and reactivities were investigated in some detail.6.A wide variety of metal complexes of the above inner salts were synthesized and their structures were investigated.

1.合成了一系列低聚硫吩环上基团堆积的萘衍生物，并对其物理化学性质进行了研究，以开发新的电子分子器件，例如，这些分子的界面低聚硫吩基相互作用，降低了其循环伏安电势。2.建立了3，6-二甲基噻吩基[3，2-b]噻吩环和3，6-二甲基硒并[3，2-b]硒的一锅法合成方法。从这些现在容易获得的单体开始，合成了它们的二聚体、三聚体和四聚体，这是一种前所未有的低聚物类型。研究了这些低聚物的物理化学性质，以期开发新的分子器件和导电聚合物。3.以二芳基乙炔和单质硫或硒为原料，一锅法合成了四芳基噻吩类和四芳基硒基苯类化合物。该合成方法的应用使低聚硫杂多烯的合成成为可能。4.合成了一系列化学性质从未被研究过的杂硫苯并三茂铁，并对其物理和化学性质进行了研究。5.合成了一类独特的内盐--二(二烷氨基)二硫代甲酸酯，并对其结构和反应活性进行了详细的研究。6.合成了多种上述内盐的金属配合物，并对它们的结构进行了研究。
