“…Instead, we direct readers to several recent and detailed review articles. [13][14][15][16] Here we carefully set out the performance metrics and instrumentation essential to characterise device performance and CP selectivity of OPDs based on chiral functional materials. We hope that this tutorial review serves to advance the field, such that CP OPDs with device performances and sensitivities compatible with the demands of real-world sensing can be realised.…”

“…The solid‐state organization of chiral organic dyes tends to prevent a perfect stacked alignment of π‐conjugated units in favor of a twisted arrangement, thus affecting relevant electro‐optical properties based on the communication between proximate molecules in the aggregated state, such as exciton migration and light emission [9] . Moreover, the introduction of chiral non‐racemic appendages in the chemical structure of π‐conjugated dyes also opens the way to a variety of highly innovative and unique technological applications as organic semiconductors in photonics and electronics: circularly polarized (CP) light emitters [10] or detectors, [11] electron spin filters, [12] chiral electrochemical sensors, [13] enantiopure chiral magnets [14] . However, studies on the optoelectronic applications of chiral supramolecular structures are still at the beginning [15] …”

The study of chiroptical properties in thin films of chiral organic π‐conjugated dyes is more complex than isotropic solutions, due to the interference of macroscopic anisotropies often present in the solid state. The experimental circularly polarized (CP) absorption (electronic circular dichroism, ECD) and CP emission (circularly polarized luminescence, CPL) of a thin film can be expressed as the sum of several terms, some of which are non‐reciprocal upon film flipping. In this review, we shall discuss the fundamental theoretical concepts about reciprocal and non‐reciprocal chiroptical features in thin films of organic dyes, describing their correlation with the solid‐state structural organization and suggesting a practical toolbox to quantify their relative weight on an experimental ECD or CPL spectrum. Moreover, we shall also take into account the literature on thin films of organic π‐conjugated dyes showing strong non‐reciprocal CP absorption and/or CP emission, due to their potential high interest in the flourishing field of chiral photonics and electronics.

“…2 Although triplet-harvesting TADF and phosphorescent emitters can achieve high device efficiencies, the luminescence g-factors are generally negligible (g E 10 À2 -10 À4 ). [3][4][5] On the other hand, LEPs display large g-factors (e.g. g E 1.0), and the potential to optimise device performance through device engineering and molecular design.…”
