The synthesis of a precursor oligocene, particularly pentacene, is a two-step process. In the fist step the Diels-Alder adduct of the a,b-dihydro-a,b-etheno-oligocene with a 1,1-dialkoxy-cyclopentadiene is formed. In the second step this Diels-Alder adduct is converted into the precursor oligocene, in that first the corresponding keto-compound is formed, which may be eliminated thereafter. The resulting precursor oligocene can be converted to the oligocene with a heat treatment, particularly after providing a solution hereof on a substrate. It is suitable for use as semiconductor material in a thin-film transistor. Formula (I).
一种前体寡聚物,特别是五环芴的合成是一个两步过程。在第一步中,将α,β-二氢-α,β-乙烯基寡聚物与1,1-二烷氧基环戊二烯的Diels-Alder加合物形成。在第二步中,将这种Diels-Alder加合物转化为前体寡聚物,首先形成相应的酮化合物,然后可能被消除。所得的前体寡聚物可以通过热处理转化为寡聚物,特别是在将其溶液涂覆在基底上后。它适用于作为薄膜晶体管中的半导体材料。公式(I)。
