Perylene fluorescence

I reworked their data to produce these. The excitation wavelength was . The quantum yield of this molecule is 0. It is used as a blue-emitting dopant material in OLEDs, either pure or substituted. Deb Kumar Bhowmick, Linda Stegemann, Manfred Bartsch, Cristian A.

Perylene displays blue fluorescence. Physics Institute, Center for Nanotechnology (CeNTech) and Center for Soft . Their fluorescence properties depend among others on the spatial arrangement and aggregation of the molecules on the surface. In the present study, silane linkers of different length and conjugation were employed to functionalize silicon carbide and silicate surfaces with two PAHs.

Ito F(1), Kogasaka Y, Yamamoto K. Fabrication and fluorescence properties of perylene bisimide dye aggregates bound to gold surfaces and nanopatterns. Experiments on the laser excited fluorescence spectrum of perylene in n-octane and ethanol hosts at low temperatures are reported. Monochromatic excitation leads to a dramatic sharpening of the emission lineS. The dependence of the spectrum on both excitation wavelength and temperature are presented and discussed . Iphenyl)- perylene -: 10-biscarboximide has been investigated by means of linear dichroism (LD), circular dichroism.


CD), and by steady-state and time-resolved fluorescence spectroscopic techniques. The absorption and emission transition . Ne, Ar, and Nmatrices are shown in Figs. The local anaesthetic tetracaine as a quencher of perylene fluorescence in micelles, J. A fluorescence quenching technique for the investigation of the configurations of binding sites for small molecules, . Plotted in Figure is the increase in the perylene fluorescence intensity as a function of the amount of solid perylene, mPE, added.


The sample fluoresces green at room temperature when illuminated with a UV handlamp. When the sample is heate the fluorescence becomes . Positions um (d) Figure 37. The image is obtained by measuring the fluorescence of the pyrene (excited at 3nm).


A brightly red fluorescent 1-hydroxyperylene bisimide was prepared by a nucleophilic aromatic displacement reaction.

The deprotonation of the hydroxy group shifts the absorption and the strong fluorescence into the NIR. Phosphorus assay in column chromatography. Fluorescence decay studies of anisotropic rotations of small molecules.
