Herein, we describe our recent expeditious synthesis of dibenzo[c]acridine helicene-like compounds on a large scale in pure enantiomeric form. This flexible synthesis allows for variation at several positions on the skeleton. Geometrical parameters related to these compounds have been obtained from monocrystal X-ray structure resolution. Additionally, chiroptical parameters have been recorded, highlighting the versatility of this family showing for example optical rotation at 589 nm varying between ...

Circularly polarized luminescence (CPL) is a fast growing research field as a complementary chiroptical spectroscopy alternative to the conventional circular dichroism or in the quest of devices producing circularly polarized light for different applications. Because chiroptical signals are generally lower than 0.1%, conventional chiral spectroscopies rely on polarization time modulation requiring step-by-step wavelength scanning and a long acquisition time. High throughput controls motivated the ...

We describe a large-scale synthesis of a series of helicene-like compounds based on a dibenzo[c]acridine fragment by the Friedlander reaction. The series includes targeted constrained (closed) derivatives comprising 11 rings that exhibit very intense circularly polarized luminescence (CPL) (glum = 8 × 10-3) contrary to their nonconstrained (open) 10-ring precursors that are not CPL active. The relationship between structure and chiroptical properties in the series is discussed with the aid of quantum-chemical ...

Stéphan Guy,

Radiation trapping causes significant lengthening of the measured fluorescence lifetimes in solid samples, which leads to overestimating them. Self-absorption inside solid-state samples is considerably enhanced by successive total internal reflections at the sample/air interface. A simple method for quantitative estimation of radiation trapping in solid-state materials within the frame of the Holstein-Biberman equations is presented. This method is based on the assumption that the radiation propagation ...

The photon-avalanche effect, which involves both absorption from a metastable intermediate level and cross-relaxation energy transfer, introduces a new trend in the achievement of efficient up-conversion lasers. In this paper, we report a quite general theoretical treatment of this process which is successfully applied to the case of ${\mathrm{LiYF}}_{4}$:${\mathrm{Nd}}^{3+}$. This model shows clearly that the avalanche effect may occur, above a pumping threshold, only if the cross-relaxation energy- ...

Upconversion pumping with yellow cw and pulsed dye lasers was used to produce uv and blue light arising from deexcitation of the $^{4}$${\mathit{D}}_{3/2}$ and $^{2}$${\mathit{P}}_{3/2}$ states of ${\mathrm{Nd}}^{3+}$ ions in ${\mathrm{BaY}}_{2}$${\mathrm{F}}_{8}$:${\mathrm{Nd}}^{3+}$. Upconversion excitation occurs via sequential two-photon absorption, which was probed by the anti-Stokes emission dynamics and by a two-color laser experiment.

The near UV, visible and near IR emissions in YAG:Tm3+ are investigated after selective one photon pumping of the 1I6, 1D2 or 1G4 manifold. Reduction of the fluorescence lifetimes as well as non-exponentiality of the decays at short times, which appear with increasing activator concentration, are indications of the cross-relaxation quenching of these excited state emissions.

Intense blue upconversion emission has been observed at room temperature under excitation in the range of 630 - 660 nm in a fluoroindate glass doped with 2.5 mol% of Tm3+ . The experimental dynamics and power dependence of this emission are well described using a photon avalanche model based on the mean field approximation.

Dynamics and power dependences of both1G4 and1D2 fluorescences under 648.7 nm excitation reveal a photon avalanche mechanism in the 3 mol% doped sample. Selective pulsed excitation indicate an almost purely radiative relaxation at low concentration in agreement with Judd-Ofelt calculations.
