Strongly dissymmetric circularly polarised (CP) luminescence from small organic molecules could transform a range of technologies, such as display devices. However, highly dissymmetric emission is usually not possible with small organic molecules, which typically give dissymmetric factors of photoluminescence (gPL) less than 10 −2.

Circularly polarized luminescence (CPL) is important to chiral photonic technologies. In molecular systems, besides their intrinsic chemical structures, architectures of molecular assemblies at the mesoscopic scale also account for the final macroscopic CPL properties.

Circularly polarized luminescence (CPL) not only can reflect the excited state structure information of chiral system, but also has wide potential applications in 3D display, communication of spin Researchers from the Imperial College London developed a new class of PLED materials that exhibit circularly polarized luminescence. Basically this means that the new materials emit polarized light which could make for more efficient Polymer-OLED devices as none of the light will be blocked by the external anti-glare circular polarizer added to the display. 2020-07-27 · Materials that exhibit circularly polarized luminescence are currently being actively investigated for applications in fields such as liquid crystal display backlights, three dimensional (3D) displays, holographic displays, light sources for controlling plant growth, and security systems for optical communications and printing. polymers with circularly polarized luminescence 2.1.

We review the recent progress in the field of helically assembled π-conjugated polymers, focusing on aromatic conjugated polymers with interchain helical π-stacking that exhibit circularly polarized luminescence (CPL). In Part 1, we discuss optically active polymers with white-colored CPL and the amplification of the circular polarization through liquid crystallinity. In Part 2, we focus on

X‐ray analysis revealed a helically twisted structure of PP units induced by axial chirality of binaphthyl framework.

This contribution reports a convenient and universal strategy for constructing chiral helical polymer/perovskite hybrid nanofibers with outstanding CPL properties. The chiral dyes showed aggregation-induced fluorescence and circularly polarized luminescence (CPL) with the Φ F and g lum of up to 0.22 and -3.5×10-3, respectively, in the solid state. The solid-state fluorescence and CPL were well characterized by the crystal packing analyses and DFT calculations. Tethering of two naphthalenes by short linkage forces a small dihedral angle, and the cyclic binaphthyls with short tether (n =1, 2) exhibit remarkable boosting of the glum value (1.0–1.6×10 −2) in circularly polarized luminescence (CPL) and unusual glum / gabs ratios (0.93–1.3).

Circularly polarized luminescence (CPL) can occur when either a luminophore or an ensemble of luminophores is chiral. The extent to which emissions are polarized is quantified in the same way it is for circular dichroism , in terms of the dissymmetry factor , also sometimes referred to as the anisotropy factor . A circularly polarized wave can rotate in one of two possible senses: clockwise or right-handed circular polarization (RHCP) in which the electric field vector rotates in a right-hand sense with respect to the direction of propagation, and counter-clockwise or left-handed circular polarization (LHCP) in which the vector rotates in a left-hand Luminescence.
