Abstract: A method for analyzing a sample with a light probe with a spatial resolution smaller than the wavelength of the light probe comprising the steps of: —illuminating the sample by a first light pulse saturating a vibrational and/or electronic transition, said light pulse presenting an intensity spatial distribution on the sample presenting at least one minimum wherein saturation does not occur, —measuring the local absorbance properties and/or the local second order non-linear susceptibility of the sample by using a second light pulse forming the light probe at a wavelength corresponding to said electronic and/or vibrational transition, wherein the second light pulse overlap said first light pulse intensity minimum.

Abstract: Borazine derivatives are used in the manufacture of electronic devices, in particular electroluminescent and semiconductor devices. More specifically, stable borazine derivatives include boron atoms substituted by aryl groups used in one or more layers of an electroluminescent or a semiconductor device, in particular in the emissive layer of organic light-emitting devices (OLED).
