Fabrication of Organic Single Crystal Transistors Based on 5,9-Diphenyldinaphtho[2,1-b:1’,2’-d]furan Derivatives

抄録

We successfully fabricated single crystal OFETs based on alkylphenyl substituted 21DNFU derivatives that are highly soluble in common organic solvents. The single crystal OFETs showed typical p-type OFET characteristics, and the field-effect mobility of the holes was estimated to be 0.2 cm²V^-1s^-1 with an I_on/I_off ratio of 10³ for 3P-21DNFU and 5P-21DNFU. The field-effect characteristics of the single crystal OFETs were strongly affected by the chain lengths of the alkyl groups and packing structures of the molecules.
