不导电的硼基主体与芳族客体的共结晶化产生导电共晶。载流子迁移率的共晶与芘或四硫富瓦烯进行了测量，使用导电探针原子力显微镜。富含π电子的芳香族客体的掺入导致导电共晶。与四硫富瓦烯作为客体的共晶显示出比与芘的共晶高约7倍的电荷载流子迁移率。
Cocrystallization of a nonconductive, boron-based host with aromatic guests generates conductive cocrystals. Carrier mobilities of the cocrystals with either pyrene or tetrathiafulvalene were measured using conducting probe atomic force microscopy. The incorporation of the pi-electron-rich aromatic guests results in electrically conductive cocrystals. The cocrystal with tetrathiafulvalene as a guest shows an approximately seven times higher charge carrier mobility than the cocrystal with pyrene.
