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 Ion/Ioff 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.
