合成了一种线型的醌二甲撑嵌苯类似物9 L，并通过X-射线晶体学分析确定了其醌型结构。9 L可以实现多个氧化态。实验和理论计算都证实了它的阳离子是三重态双自由基，四价离子可以看作是九并苯的等电子结构。
Linear quinodimethane-embedded acene analogue 9L was synthesized, and its quinoidal structure was confirmed by X-ray crystallographic analysis. The multiple oxidation states of 9L could be achieved. Its dication is a triplet diradical, and its tetracation can be regarded as the isoelectronic structure of the nonacene, which was validated by experiments and theoretical calculations.
