A large number of graphene molecules, or large polycyclic aromatic hydrocarbons (PAHs), have been synthesized and display various optoelectronic properties. Nevertheless, their potential for application in photonics has remained largely unexplored. Herein, we describe the synthesis of a highly luminescent and stable graphene molecule, namely a substituted dibenzo[hi,st]ovalene (DBO 1), with zigzag
大量的石墨烯分子或大的多环芳烃(PAH)已合成,并显示出各种光电性能。然而,它们在光子学中的应用潜力仍未得到充分开发。本文中,我们描述了一种高发光和稳定的石墨烯分子的合成,即具有锯齿形边缘的取代的二苯并[ hi,st ]戊烯(DBO 1),并通过超快速瞬态吸收光谱法阐明了其有希望的光学增益特性。在将DBO掺入惰性聚苯乙烯基质中时,可以以相对较低的功率阈值(约60μJcm -2)观察到放大的受激发射,从而突出了其在激光应用中的高潜力。
