“…In order to integrate individual multiple liquid OLEDs on one substrate, we fabricated single-m-thick electro-microfluidic devices using MEMS process and heterogeneous bonding technology through the use of amine-and epoxy-terminated self-assembled monolayers (SAMs) [20][21][22][23][24]. Figure 2 shows the design of a prototype microfluidic OLED that consists of a 3 x 3 array of light-emitting pixel in SU-8-based microchannels.…”

Liquid organic semiconductors (LOSs) have been an attractive class of functional materials for next generation organic electronic devices. In 2009, a liquid organic light-emitting diode (Liquid OLED), which consists of LOS in the active layer, was proposed by Xu and Adachi. Although several papers have reported on an improvement in device performance, from the viewpoint of the device architecture, there are challenges associated with multi-color electroluminescence (EL) emissions. In order to integrate multiple individual liquid OLEDs on one substrate, we have developed multi-color microfluidic OLEDs which have single-m-thick microchannels sandwiched between two electrodes. This paper presents a brief overview of the authors' own recent progress on the microfluidic OLED technologies, including fabrication methodology for electro-microfluidic devices and demonstration of multi-and white-color EL emissions using pyrene-based LOSs. We believe that the proposed microfluidic OLEDs can be promising for novel liquid-based device applications.

“…Second, the apertures of the ECL electrodes were designed to be larger than what was reported previously to allow for increased surface-area for luminophore generation (for increased sensitivity). Third, each working electrode (WE) was formed from bare (transparent) ITO [rather than gold ] to allow for convenient optical detection [note that ITO WEs have been extensively employed for generating ECL in microchannel devices (Kasahara et al 2014;Wu et al 2015)]. …”

“…The microchannel and microchamber structures are usually fabricated via microelectromechanical systems (MEMS) technologies including photolithography and etching processes. In our previous work, we proposed a patterning method for liquid emitting layers on a single device using microfluidic technologies, and the negative photoresist SU-8-based electro-microfluidic device was fabricated on a glass substrate using MEMS processes and the heterogeneous bonding technique through the use of self-assembled monolayers (SAMs) [25,26]. In this microfluidic device, the SU-8 microchannels were sandwiched between the ITO on a glass substrate (anode substrate) and the polyethylene naphthalate (PEN) film with the amine-terminated SAM-coated ITO (cathode substrate).…”
