Highly stable N,N′-ditridecyl-3,4,9,10-perylenetetracarboxylic diimide (PTCDI-C13) colloids of 0.1 wt% concentration were prepared successfully by laser ablation technique in acetonitrile. Mean particle size of the prepared PTCDI-C13 colloid measured by dynamic light scattering method was smaller than 50 nm which is also confirmed by a transmission electron microscope observation. By simple drop-casting of prepared PTCDI-C13 colloids, typical n-type OTFTs with good saturation properties were fabricated successfully. The highest electron mobility was 1.1 × 10−3 cm2/Vs and increased up to 0.027 cm2/Vs by post-annealing treatment., Article, ORGANIC ELECTRONICS. 14(1):19-25 (2013)},
