A series of 9,9′-dianthrylpoly-ynes (II1–II6) were prepared, and their electronic spectra were measured. It was found that the novel linear relation between λmax and the square of the number of the triple bond (n2) which has been found in the spectra of 1,1′-dianthrylpoly-ynes (I1–I6) also held in the 9,9′-series.
合成了系列9,9′-联蒽基聚乙炔(II1–II6),并测定了它们的电子光谱。发现,如同1,1′-联蒽基聚乙炔(I1–I6)光谱中所见,λmax与三键数目(n)平方的线性关系在9,9′-系列中也成立。
