Understanding the pressure and shear dependence of viscosity is essential to an understanding of the mechanisms of film forming and friction in concentrated contacts. The blending of different molecular mass polyalphaolefins (PAOs) may permit the for

We have electrospun light-emitting nanofibers from ruthenium(II) tris(bipyridine)/polyethylene oxide mixtures. The electroluminescent fibers were deposited on gold interdigitated electrodes and lit in a nitrogen atmosphere. The fibers showed light em

Synchrotron X-ray diffraction from a nominally amorphous molecular semiconductor film reveals both the presence of intermediate-range order (IRO) corresponding to crystalline domains with an average size of a few nanometres, and the growth of these d

We have used in situ Raman spectroscopy to identify a luminescence quencher formed during organic light-emitting device operation. Raman spectroscopy revealed that oxo-bridged dimerization occurs during the operation of [Ru(bpy)3]2+(PF6−)2 devices,

Electronic devices primarily use electronic rather than ionic charge carriers. Using soft-contact lamination, we fabricated ionic junctions between two organic semiconductors with mobile anions and cations, respectively. Mobile ionic charge was succe

We have used matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry and micro-Raman spectroscopy to identify a quenching species that is formed during operation of [Ru(bpy)3]2+ electroluminescent devices. We identify

We have prepared and characterized a series of multimetallic oligomers of Ru using the pi-conjugated bridging ligand tetra-2-pyridyl-1,4-pyrazine (tppz), as well as mixed-ligand complexes with terpyridine end caps, and analyzed their electrochemical

Evaluation of the steric and electronic influence of a family of silyl- and alkyl-substituted indenyl ligands on zirconium and iron centers has been accomplished by a combination of X-ray diffraction, IR spectroscopy, solution NMR dynamics, and elect

We have investigated the temperature dependence of the current, radiance, and efficiency from electroluminescent devices based on [Ru(bpy)3]2+(PF6−)2, where bpy is 2,2′-bipyridine. We find that the current increases monotonically with temperature

Absorption and luminescence spectra as well as luminescence lifetimes have been measured for Ru(bpy)2+3 in solution and in thin films of varying thicknesses, and these properties have been correlated with the efficiency of organic light emitting devi
