Abstract
Abstract Here we describe a method of patterning electroluminescent (EL) polymers using micromolding in capillary (MIMIC). MIMIC is the one of the lithographic methods based on the microfludics among the soft lithography using a patterned poly(dimethylsiloxane) (PDMS) elastomer. The patterned microstructures of poly(dioctylfluorene) (PDOF), poly( p -phenylenevinylene) (PPV), and poly(2-methoxy-5-2′-ethylhexyloxy)- p -phenylenevinylene) (MEH-PPV) were fabricated by MIMIC for polymer light-emitting diodes (PLEDs). In addition, the solution viscosity effect on MIMIC process was studied. Finally, a PLED device was fabricated using the patterned EL polymer microstructure and a patterned emission image was obtained.
