Abstract

High performance single-crystalline organic field-effect transistors (OFETs) based on the derivatives of a single dibenzo[a,e]-pentalene (DBP) skeleton have not been reported. Here, we synthesize two novel compounds, 5,10-bis((E)-2-(thiophen-2-yl)vinyl)indeno[2,1-a]indene (TEP) and [4′-(methoxyl)styryl]dibenzopentalene (OSDP), and demonstrate single-crystalline OFET devices. TEP OFETs exhibit a high record of hole mobility up to 1.02 cm2 V−1 s−1 among DBP derivatives, which is an order of magnitude higher than that of OSDP OFETs. The investigation indicates that the different substituent groups and resulting packing arrangements determine their distinct charge transport properties. The comparative results may provide guidance for the rational design and development of high-performance organic semiconducting materials in the future.
