Aggregation-Induced Emission: Together We Shine, United We Soar!

Luminogenic materials with aggregation-induced emission (AIE) attributes have attracted much interest since the debut of the AIE concept in 2001. In this critical review, recent progress in the area of AIE research is summarized. Typical examples of AIE systems are discussed, from which their structure–property relationships are derived. Through mechanistic decipherment of the photophysical processes, structural design strategies for generating new AIE luminogens are developed. Technological, especially optoelectronic and biological, applications of the AIE systems are exemplified to illustrate how the novel AIE effect can be utilized for high-tech innovations (183 references).

Aggregation-induced emission

"United we stand, divided we fall."--Aesop. Aggregation-induced emission (AIE) refers to a photophysical phenomenon shown by a group of luminogenic materials that are non-emissive when they are dissolved in good solvents as molecules but become highly luminescent when they are clustered in poor solvents or solid state as aggregates. In this Review we summarize the recent progresses made in the area of AIE research. We conduct mechanistic analyses of the AIE processes, unify the restriction of intramolecular motions (RIM) as the main cause for the AIE effects, and derive RIM-based molecular engineering strategies for the design of new AIE luminogens (AIEgens). Typical examples of the newly developed AIEgens and their high-tech applications as optoelectronic materials, chemical sensors and biomedical probes are presented and discussed.

Aggregation-Induced Emission: The Whole Is More Brilliant than the Parts

Pyrene-based materials for organic electronics.

A hybrid analog-digital driving method has been proposed for driving the AMOLED. A frame has been divided into N subframes corresponding to the N bit image data. Each subframe is binary weighted by either the duration or the pixel “on” luminance. The pixel “on” luminance is controlled by the voltage level of the common cathode of the OLED (Vcom). By changing the amplitude of Vcom, the “on” luminance can be binary varied. The proposed driving scheme can be applied to a 4K or even 8K UHD AMOLED with 8-bit gray level.

Synthesis, aggregation-induced emission, and electroluminescence properties of a novel emitter comprising tetraphenylethene and carbazole moieties

One of the considerable effects that limit the performance of white quantum dot (QD) light‐emitting diodes (W‐QLEDs) is the Förster resonance energy transfer (FRET) among different colored QDs. Here, the FRET mechanisms among QDs are unraveled and how FRET affects the performance of W‐QLEDs is disclosed. The results show that although FRET is beneficial for harvesting the energy of nonradiative excitons, it is unhelpful for the improvement of the total emission quantum yield of bi‐color or tri‐color QDs. Due to the existence of FRET, a large proportion of blue QDs should be incorporated to obtain a balanced white emission, which remarkably deteriorates the efficiency of the white emission. With the developed device structure, the FRET among QDs can be suppressed, and thus, the external quantum efficiency (power efficiency) of the W‐QLEDs is improved from 9.31% to 27.03% (12.18–25.52 lm W−1), representing an improvement factor of 2.9 (2.1) compared with that of the conventional W‐QLEDs. The results not only deepen the insight into the FRET mechanisms among QDs but also provide solutions and inspirations for the future development of efficient W‐QLEDs.

A new structure for thin-film transistors, exhibiting the benefits but not the drawbacks of both short-channel and multijunction effects, is proposed and demonstrated. Theoretical modeling is performed to understand the physics of this device structure. All characteristics such as threshold voltage, pseudo subthreshold slope, on–off current ratio, and field-effect mobility are improved.
