Engineering the morphologies and charge transport by controlling various side groups |
| 초록 |
The microstructure of small molecular semiconductors can be readily altered via side group-engineering although they have same conjugated core. Here, we study a variation of morphology and charge transport properties depending on side group size. It was verified that combined with smaller side group developed more favorable morphology to charge carrier transport.. In addition, a high (1,2,4-trichlorobenzene; TCB) and low (chlorobenzene; CB) boiling point was used as processing solvent to observe the effect of the film fabrication time on the molecular ordering according to side group size. Side group engineering can be used to control of molecular ordering and packing pattern of semiconducting PAHs. The smaller side group induced the more uniform molecular packing and the higher OFET property. The small molecular semiconductors has amorphous morphology and lowest OFET performance because its long side groups interrupt molecular organization. |
