摘要：
The morphological and electrical properties of 2,11-di-tert-buty1-6,7, 15,16-tetrakis(hexylthio)quinoxalino[2',3': 9,10]phenanthro[4,5-abc]phenazine (TQPP) organic molecule combined with butylamine (BAM)-modified graphene sheets (GSs) are described. The grafting of the amine onto the graphene sheet plane promotes its compatibility with this BAM soluble molecule, leading to the preparation of homogeneous films containing exfoliated graphene sheets, as demonstrated by infrared spectroscopy, field emission electron microscopy, and Raman spectroscopy. The film deposited from the BAM-modified GSs/TQPP blend showed a photoelectrical response higher than those prepared with neat molecule and GSs/TQPP blend, respectively.
