Unraveling Unprecedented Charge Carrier Mobility through Structure Property Relationship of Four Isomers of Didodecyl[1]benzothieno[3,2-b][1]benzothiophene.
ADVANCED MATERIALS(2016)
摘要
The structural and electronic properties of four isomers of didodecyl[1]benzothieno[3,2-b][1]benzothiophene (C12-BTBT) have been investigated. Results show the strong impact of the molecular packing on charge carrier transport and electronic polarization properties. Field-induced time-resolved microwave conductivity measurements unravel an unprecedented high average interfacial mobility of 170 cm(2) V-1 s(-1) for the 2,7-isomer, holding great promise for the field of organic electronics.
