Combining Lanthanides with PyBox Ligands: A Simple Route to Circularly Polarized Light Emitters**

نویسندگان

چکیده

We report the facile synthesis of TbIII and EuIII adducts able to elicit circularly polarized luminescence. Both sensitization lanthanide-ion-centered luminescence (i. e. antenna effect) chiral environment around metal ions are brought about by commercially available enantiopure 2,6-bis(oxazolinyl)pyridine ligands (PyBox). This strategy is promising for development a wide range new simple (CPL) active LnIII adducts, thanks fine tunability chemical structure PyBox ligands.

Recollisions and correlated double ionization with circularly polarized light.

It is generally believed that the recollision mechanism of atomic nonsequential double ionization is suppressed in circularly polarized laser fields because the returning electron is unlikely to encounter the core. On the contrary, we find that recollision can and does significantly enhance double ionization, even to the extent of forming a "knee," the signature of the nonsequential process. Us...

All-optical magnetic recording with circularly polarized light.

We experimentally demonstrate that the magnetization can be reversed in a reproducible manner by a single 40 femtosecond circularly polarized laser pulse, without any applied magnetic field. This optically induced ultrafast magnetization reversal previously believed impossible is the combined result of femtosecond laser heating of the magnetic system to just below the Curie point and circularly...

Dual wavelength asymmetric photochemical synthesis with circularly polarized light.

Asymmetric photochemical synthesis using circularly polarized (CP) light is theoretically attractive as a means of absolute asymmetric synthesis and postulated as an explanation for homochirality on Earth. Using an asymmetric photochemical synthesis of a dihydrohelicene as an example, we demonstrate the principle that two wavelengths of CP light can be used to control separate reactions. In doi...

Time delay in atomic photoionization with circularly polarized light

We study time delay in atomic photoionization by circularly polarized light. By considering the Li atom in an excited 2p state, we demonstrate a strong time delay asymmetry between the photoemission of the target electrons that are coand counter-rotating with the electromagnetic field in the polarization plane. In addition, we observe the time delay sensitivity to the polar angle of the photoel...
