제목 Hole transport properties of newly small molecules by containing 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. The smallest side group, formed well-connected crystal domain with well-ordered molecular assemblies which facilitate fast 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.
