“…In addition, in the context of a growing development of VUV/XUV CPL sources from FELs 57 , HHG 29,58,59 , plasma--based laser 60 and associated polarizing optics 61 , PECD could, like other dichroic effects 62 , be used as a "molecular polarimeter template", especially when either the β parameter is null or known, or when the linear polarization components of light (S1 and S2) are negligible, in which case accurate PECD benchmarking with the present data would allow the disentangling of the unpolarized component (S4) from the circular one (S3). This would be a complementary approach from the molecular polarimetry data deduced from molecular--frame photoelectron angular distributions (MF--PADs), recently demonstrated 63 and valid in the dissociative ionization continuum range of small molecules, i.e., above 20 eV or so.…”

Photoelectron circular dichroism (PECD) manifests itself as an intense forward/backward asymmetry in the angular distribution of photoelectrons produced from randomly--oriented enantiomers by photoionization with circularly--polarized light (CPL). As a sensitive probe of both photoionization dynamics and of the chiral molecular potential, PECD attracts much interest especially with the recent performance of related experiments with visible and VUV laser sources. Here we report, by use of quasi--perfect CPL VUV synchrotron radiation and using a double imaging photoelectron/photoion coincidence (i 2 PEPICO) spectrometer, new and very accurate values of the corresponding asymmetries on showcase chiral isomers: camphor and fenchone. These data have additionally been normalized to the absolute enantiopurity of the sample as measured by a chromatographic technique. They can therefore be used as benchmarking data for new PECD experiments, as well as for theoretical models. In particular we found, especially for the outermost orbital of both molecules, a good agreement with CMS--Xα PECD modeling over the whole VUV range. We also report a spectacular sensitivity of PECD to isomerism for slow electrons, ...

Long‐Persistent Circularly Polarized Phosphorescence from Chiral Organic Ionic Crystals

Long‐persistent circularly polarized phosphorescence (LPCPP) is achieved for the first time in chiral organic ionic crystals at room temperature. The co‐crystal composed of terephtalic acid (TPA) and chiral α‐phenylethyamines (PEAs) gave rise to LPCPP with lifetimes up to 862 ms and large dissymmetric factor (glum). The hybridization of TPA with chiral PEAs allows circular polarization of the generated long‐persistent phosphorescence. The observed mirror‐image twisted molecular structures in the rigid lattices were responsible for the chiroptical activation of the generated long‐persistent phosphorescence.

“…Thus, distinguishing between two polarization states of CPL is in high demand. Conventional optical CPL detectors rely on an achiral photodetector with a linear polarizer and quarter waveplate . Such a complicated device configuration does not meet the demands of miniaturization trends, which is also incompatible with the emerging wearable technology.…”

A Chiral Reduced‐Dimension Perovskite for an Efficient Flexible Circularly Polarized Light Photodetector

et al. 2020

Chiral quasi‐2D perovskite single crystals (SCs) were investigated for their circular polarized light (CPL) detecting capability. Quasi‐2D chiral perovskites, [(R)‐β‐MPA]2MAPb2I7 ((R)‐β‐MPA=(R)‐(+)‐β‐methylphenethylamine, MA=methylammonium), have intrinsic chirality and the capability to distinguish different polarization states of CPL photons. Corresponding quasi‐2D SCs CPL photodetector exhibit excellent detection performance. In particular, our device responsivity is almost one order of magnitude higher than the reported 2D perovskite CPL detectors to date. The crystallization dynamics of the film were modulated to facilitate its carrier transport. Parallel oriented perovskite films with a homogeneous energy landscape is crucial to maximize the carrier collection efficiency. The photodetector also exhibits superior mechanical flexibility and durability, representing a promising candidate for sensitive and robust CPL photodetectors.
