compounds for organic electronics and optics. However, the instability and low solubility of larger starphene homologs make their synthesis extremely challenging. Herein, we present a new strategy leading to pristine [16]starphene in preparative scale. Our approach is based on a synthesis of a carbonyl‐protected starphene precursor that is thermally converted in a solid‐state form to the neat [16]starphene
由于
苯乙炔具有独特的理化特性,因此它们是有吸引力的化合物,使它们成为有机电子和光学的有趣化合物。然而,较大的星形
酚同系物的不稳定性和低溶解度使它们的合成极具挑战性。在本文中,我们提出了一种在制备规模上导致原始[16]星
