Abstract

Butadiyne-linked linear and cyclic carbazole oligomers were successfully synthesized. The intensity of the emission band in the 0-0 band of the highly planar macrocyclics decreased compared to that of the 0-1 band. Contrary to this, for larger macrocycles having reduced planarity, the intensity of the emission of the 0-0 band increased as in the cases of the linear compounds. This suggests that the emission color of the π-conjugated molecule can be controlled not only by the difference between the cyclic and chain structures but also by the control of the planarity, and is expected to be a new principle for molecular design in the development of fluorescent materials.

摘要

成功合成了丁二炔连接的线性和环状咔唑低聚物。与0-1带相比，高度平面大环化合物在0-0带发射带的强度降低。与此相反，对于平面度降低的较大大环化合物，0-0带发射强度如线性化合物那样增加。这表明π共轭分子的发射颜色不仅可以通过环状和链状结构之间的差异来控制，还可以通过平面度的控制来实现，有望成为荧光材料开发中分子设计的新原理。
