“…In recent years, OLEDs have experienced significant improvements including better efficiency, high brightness, and low drive voltage. These advances have helped to realize high‐efficiency full‐color and white‐color OLEDs 1–3, 12, 13. In order to achieve highly efficient OLEDs, efficacious and balanced electron‐ and hole‐injection/transport from the cathodes and anodes is essential.…”

The field of organic electronics has been developed vastly in the past two decades due to its promise for low cost, lightweight, mechanical flexibility, versatility of chemical design and synthesis, and ease of processing. The performance and lifetime of these devices, such as organic light‐emitting diodes (OLEDs), photovoltaics (OPVs), and field‐effect transistors (OFETs), are critically dependent on the properties of both active materials and their interfaces. Interfacial properties can be controlled ranging from simple wettability or adhesion between different materials to direct modifications of the electronic structure of the materials. In this Feature Article, the strategies of utilizing surfactant‐modified cathodes, hole‐transporting buffer layers, and self‐assembled monolayer (SAM)‐modified anodes are highlighted. In addition to enabling the production of high‐efficiency OLEDs, control of interfaces in both conventional and inverted polymer solar cells is shown to enhance their efficiency and stability; and the tailoring of source–drain electrode–semiconductor interfaces, dielectric–semiconductor interfaces, and ultrathin dielectrics is shown to allow for high‐performance OFETs.

“…There has been wide interest in the photophysical properties of rod-like conjugated polymers because of their potential applications in various optoelectronic devices, especially in polymer light-emitting diodes (PLEDs). Polyfluorenes (PFs), 1-3 polythiophenes (PTs), 4 poly(p-phenylenes) (PPPs), 5 poly(p-phenylenenvinylenes) (PPVs), 6 and their derivatives are several classes of prime rod-like polymers as lightemitting materials, high quantum efficiencies and excellent prospects for device applications. In general, rigid-rod polymers do not melt and have poor solubility in most organic solvents.…”

A series of fluorene-alt-benzene based conjugated main chain polymers attached chemically with different lengths of alkyl side chains on phenylene rings were designed and synthesized by a palladium catalyzed Suzuki coupling reaction. The UV-vis absorption and fluorescence spectra, thermal stability of spectral property, phase transition behavior and morphology of the synthesized polymers were investigated. With increasing the length of the alkyl side chain, the UV and fluorescence spectra exhibit obvious blue shift compared with those of the unsubstituted polymer. The alkyl substitution improves the thermal stability of the spectra due to the steric hindrance of the alkyl side chains and thus the effective separation of the main chain backbones. The phase transition behavior is closely related to the length of alkyl side chains attached on the phenylene rings. The annealed polymer films display characteristic nematic liquid crystalline texture. Transmission electron microscopy (TEM) observations indicate that solvent-cast thin deposits of all the polymers show typical fibrillar morphology.

“…In other words, the nanoscale control of structure, size, sequence, conformation, shape and distribution of functional building blocks, such as π‐conjugated segments, in polymers and the nanoscale tailoring of arrangement, morphology and interface of the resulting functional polymers is essential for highly efficient electronic materials and devices. A number of reviews on plastic electronics have been published 8–16. In this review, we highlight the state‐of‐the‐art development of interface‐tailored and nanoengineered polymeric materials to optimize the performance of (opto)electronic devices.…”

For plastic (opto)electronic devices such as light-emitting diodes (LEDs), photovoltaic (PV) cells and field-effect transistors (FETs), the processes of charge (hole/electron) injection, charge transport, charge recombination (exciton formation), charge separation (exciton diffusion and dissociation) and charge collection are critical to enhance their performance. Most of these processes are relevant to nanoscale and interfacial phenomena. In this review, we highlight the state-of-the-art developments of interface-tailored and nanoengineered polymeric materials to optimize the performance of (opto)electronic devices. These include (1) interfacial engineering of anode and cathode for polymer LEDs; (2) nanoengineered (C 60 and inorganic semiconductor nanoparticles) π -conjugated polymeric materials for PV cells; and (3) polymer and monolayer dielectrics/interfaces for FETs and light-emitting and nano-FETs.
