There have been many efforts to fabricate vacuum- and/or solution-processable organic semiconductor layers for high performance OFETs, light emitting diodes, and other electronic devices. Here, effects of dielectric interface properties have been introduced to understand self-assembly of π-conjugated oligomers and polymers, and to realize low-cost and large-area organic electronics with highly environmental stability and low operating voltages. Solution-processable triethylsilyethynyl anthradithiophene films on solution-patterned polymer dielectrics with low dielectric constants, showed high performances in OFETs (mobility, ~ 1.2 cm2/Vs and on-off ratio, ~107), operating even at VG＜±2V. Via controlling the molecular interaction between P3HT-based block copolymers and dielectrics, ordered hetero-junction organic photovoltaics has also been demonstrated. |
