Controlling vertical alignment of phthalocyanine nanofibers on transparent graphene-coated ITO electrodes for organic field emitters

Experimental and theoretical investigation of enhanced cold cathode emission by plasma-etched 3d array of nanotips derived from CuPc nanotube

“…The eld emission characteristics are shown in the Fig. [10][11][12][13][14][21][22][23][24][25][26] These values are also comparable various tube like eld emitter such as B-C-N microtube, Fe doped TiO 2 nanotube, ZnO nanotubes, boron nanotubes and carbon nanotubes. The turn-on eld and threshold eld in the case of CuPc nanotube was obtained 6.8 and 8.4 V mm À1 respectively, which get down-shied to 4.2 and 6.5 V mm À1 for the P-CuPc nanotips respectively.…”

“…In comparison to its peers, FED has advantages such as higher brightness, lower power consumption, larger color gamut and shorter response time. [7][8][9][10][11][12][13][14][15] Being highly resistant to chemical and thermal degradation, copper phthalocyanine CuPc is a superior candidate as a eld emitter among the organic semiconductors. Inspired by this speculated array of exciting features, several groups have focused their attentions to design excellent cold cathode emitting materials.…”

Self-assembled coronene nanofiber arrays: toward integrated organic bioelectronics for efficient isolation, detection, and recovery of cancer cells

“…Based on observational evidence of the template-assisted self--assembly of OSM semiconductors, 14 we have previously found that it is possible that rGO coatings and thermal evaporation can be used to control the vertical alignment of OSM (e.g., phthalocyanine) NFs on transparent ITO electrodes. With the goal of developing integrated transparent bioelectronic interfaces for the efficient isolation and detection of cancer cells, in this study we developed a simple approach-using three different transparent conducting electrodes (ITO, GO-coated ITO, rGO-coated ITO)-for controlling the growth of nanostructured CR-based thin lms, which we studied as NF arrays for their corresponding cell-capture performance (Fig.…”

“…For example, the in-plane morphologies (planar structures) of small-molecule thin lms have been exploited widely in organic light emitting diodes (OLEDs) and organic eldeffect transistors (OFETs), 9 while out-of-plane three-dimensional (3D) morphologies [nanober (NF) arrays] of active layers have been generally developed for organic photovoltaics (OPVs) and organic eld emitters. [10][11][12][13][14] Although the use of organic small molecule (OSM) semiconductors as device active layers has been examined for the development of organic bioelectronics, [15][16][17] practical examples of their applications in cell-based bioelectronics have been very rare, due to the lack of reliable techniques for controlling the 3D morphologies of OSM thin lms and for regulating cell-matrix interactions at the device level.…”

Multifunctional Graphene–PEDOT Microelectrodes for On‐Chip Manipulation of Human Mesenchymal Stem Cells

“…Device Fabrication with Alternating rGO–PEDOT Microelectrode Arrays : Figure 5a–e presents a schematic representation of the fabrication of rGO‐PEDOT microelectrode arrays; this procedure was identical to that described previous reports 27, 46. Briefly, GO was first synthesized based on a modified version of Hummers method 47.…”
