“…Since then, enormous progress has been made in the macromolecular engineering of the !-conjugated polymers and in their uses as active materials in polymeric light-emitting diodes (PLEDs) [2][3][4][5][6]. These polymers are promising organic analogues of inorganic semi-conducting materials, and their exploitation in other electronic devices, such as thin-film transistors [7,8], photovoltaic cells [9,10], chemical sensors [11] and organic lasers [12] are currently expanding.…”

Abstract. New conjugated PPV derivatives containing the chiral isosorbide group (P1-3) have been synthesized via the Gilch reaction. The polymers are optically active, soluble in common organic solvents and show good film-forming abilities. High number-average molecular weights were determined by size exclusion chromatography (SEC) (16·10 3 -21·10 3 g·mol -1 ). The molecular structures of the polymers were confirmed by nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopies. Thermogravimetric analysis of the polymers showed good thermal stability up to 320°C. The optical properties of these !-conjugated materials were investigated by UV-vis absorption and photoluminescence (PL) spectroscopies. The polymers show a yellow fluorescence in dilute solution, and an orange emission is observed in thin films. The introduction of the polar isosorbide groups improved the PL intensity, and quantum yields between 50 and 73% were obtained. The HOMO-LUMO energy levels were estimated by cyclic voltammetry, and the electrochemical gaps were 1.81, 1.83 and 2.48 eV for P1, P2 and P3, respectively. Single-layer diode devices were fabricated and show relatively low turn-on voltages between 3.1 and 3.4 V.

This intractability has been addressed by chemically attaching aliphatic side-chains to the polymer backbone [19]. Hence, many PPV-type architectures are processed in a derivative form. The effects of the side-group structure on the opto-electronic properties have been extensively investigated [20]. However, most studies have involved nonpolar sidechains, and the effect of relatively polar side-groups was rarely reported (e.g PPV derivative containing ethylene oxide-type side chains) [12]. Here, we report the first PPV derivatives containing the polar and chiral isosorbide groups. In fact, the incorporation of chiral groups in polypyrroles and polythiophenes was reported. These groups confer original physico-chemical properties to the polymer [21][22][23]. Therefore, these optically active polymers were used to prepare chiral electrodes for asymmetric electrosynthesis, polarization-sensitive electro-optical devices, polarized photo-and electroluminescent devices and enantioselective sensors [24]. Herein, we present the synthesis and structural characterizations of the isosorbide-containing PPVs; the thermal, thin film surface, optical and electrochemical properties were investigated.

“…As opposed to the subtractive fabrication processes commonly employed in the production of circuits, such as etching, basic electronic components can be fabricated using processes such as screen, gravure, inkjet, and aerosol jet printing among many others [26][27][28][29]. The significance of these techniques is their ability to create circuits directly upon a target substrate.…”

All-printed smart structures: a viable option?

The last two decades have seen evolution of smart materials and structures technologies from theoretical concepts to physical realization in many engineering fields. These include smart sensors and actuators, active damping and vibration control, biomimetics, and structural health monitoring. Recently, additive manufacturing technologies such as 3D printing and printed electronics have received attention as methods to produce 3D objects or electronic components for prototyping or distributed manufacturing purposes. In this paper, the viability of manufacturing all-printed smart structures, with embedded sensors and actuators, will be investigated. To this end, the current 3D printing and printed electronics technologies will be reviewed first. Then, the plausibility of combining these two different additive manufacturing technologies to create all-printed smart structures will be discussed. Potential applications for this type of all-printed smart structures include most of the traditional smart structures where sensors and actuators are embedded or bonded to the structures to measure structural response and cause desired static and dynamic changes in the structure.

“…[93] Marcello et al [94] developed a completely integrated OLED-based protein biochip for human antigen detection by coupling the OLED emission spectrally to an antibody-conjugated fluorophore (as a marker). Vapor-phase microprinting of different phosphorescent OLEDs [95] and different chemically light-emitting polymers [49] can thus be seen as potential sources for arrayed detection techniques, given reports of use of printing methods to development of integrated flexible sensors. [96] Integration of wearable sensors [97] can lead to other applications such as analysis of human sweat, which contains an immense amount of diagnostic information.…”

Printed light sources, imaging systems and displays have revolutionized modern lifestyle by enriching visual feedback of various devices that human beings interact with. Despite the overall vastness of the field, there have been few to no attempts to place recent progress in these systems in sensor systems. In this short topical review, we survey the current state of art in printed light sources, imaging systems and displays specifically geared towards sensor applications. We find that the definition of displays needs to generalized in light of the availability of disposable colorimetric sensors for various chemical and biological markers. Recent exemplars of progress in each identified area are briefly presented and in conclusion, an overall view of the trends represented by these achievements is discussed.
