This paper mainly introduces the light-emitting mechanism, preparation technology, and application status of electroluminescent polymer materials. As an important category of conductive polymer, electroluminescent polymer materials are also known as organic electroluminescent (EL) diode materials or organic light-emitting diode (OLED) materials. Compared with traditional display materials and devices, OLED materials boast a high light-emitting efficiency, an easily adjustable wavelength, a long service life, and an excellent machining performance. In the light of these advantages, this paper summarizes the progresses and future trends of OLED materials and devices in green lighting and panel display.

Increasing the quantum yield of near-infrared (NIR) emissive dyes is criticalf or biological applications because thesef luorescent dyes generally show decreased emission efficiency under aqueous conditions. In this work, we designed and synthesized several multiarylpyrrole (MAP) derivatives, in which af uranylidene (FE) group at the 3-position of the pyrrole forms donor-p-acceptor molecules, MAP-FE, with aN IR emissive wavelength and aggregation-enhanced emission (AEE) features. Different alkyl chains of MAP-FEs linked to phenylg roups at the 2,5-position of the pyrrole ring resulted in different emissive wavelengths and quantum yields in aggregated states, such as powders or single crystals. Powder XRD dataa nd single crystal analysis elucidated thatt he different lengths of alkyl chains had a significant impact on the regularity of MAP-FEs when they were forced to aggregate or precipitate, which affected the intermolecular interaction and the restriction degree of the rotatingp arts, which are essential components.T herefore, an increasing number of NIR dyes could be developed by this designs trategy to produce efficient NIR dyes with AEE. Moreover, this method can provide general guidance for other relatedf ields, such as organic solarc ells and organic light-emitting materials, because they are all applied in the aggregated state.

“…They also lend themselves to tunability in terms of their optical properties. The Diketopyrrolopyrrole (DPP) family of materials has found wide-range applicability in the field of organic field-effect transistors, 9 organic solar cells, 10 organic light emitting diodes, 11 photocatalysis 12 and fluorescent sensors. 13 The photophysics of DPP based materials is on the other hand, is an active area of research owing to the flexibility in the conformational possibilities as well as their tunability from their functionalization.…”
