Helitwistacenes—Combining Lateral and Longitudinal Helicity Results in Solvent‐Induced Inversion of Circularly Polarized Light

Israa Shioukhi, Harikrishna Batchu, Gal Schwartz, Louis Minion et autres

Abstract Helicity is expressed differently in ortho‐ and para‐fused acenes—helicenes and twistacenes, respectively. While the extent of helicity is constant in helicenes, it can be tuned in twistacenes, and the handedness of flexible twistacenes is often determined by more rigid helicenes. Here, …

The effect of axial and helical chirality on circularly polarized luminescence: lessons learned from tethered twistacenes

Anjan Bedi, Gal Schwartz, Uri Hananel, Amit Manor Armon et autres

The effect of axial and helical twisting on the circularly polarized luminescence of acenes was studied both experimentally and computationally, using four series of tethered twisted acenes. We find that the combination of axial and helical chirality yields the highest anisotropy factors, …

Circularly polarized and total luminescence as probes of nucleation and growth in chiral nanocrystals

Gal Schwartz, Uri Hananel, Gil Markovich

-doped terbium phosphate nanocrystals are an interesting system for studying nanocrystal formation mechanisms and chiral symmetry breaking, occurring during their formation, directed by chiral ligands, such as tartaric acid. In this paper, we show how simultaneous, in situ monitoring of both total …

Time‐resolved circularly polarized luminescence of Eu3+‐based systems

Uri Hananel, Gal Schwartz, Guy Paiss, Lorenzo Arrico et autres

Abstract Chiral Eu3+‐based systems are frequently studied via circularly polarized luminescence spectroscopy. The emission lifetimes of each circular polarization, however, are virtually always ignored, because in a homogeneous sample of emitters, there should be no difference between the two. However, we show …
