Solution-Processable Polyphenylphenyl Dendron Bearing Molecules for Highly Efficient Blue Light-Emitting Diodes
摘要:
Novel solution-processable blue light-emitting materials Blue A-D, bearing a polyphenylphenyl dendron, have been synthesized and characterized. The energy levels and band gaps can be facilely tuned by changing the central aromatic ring of the molecules. A highly efficient deep blue light-emitting OLED device based on Blue C with a maximum current efficiency of 2.2 cd/A has been achieved using PVK as the host material through a solution process.

The present invention relates to a compound of the general formula (1). The compound of formula (1) is suitable for use in a method for treating a disorder relating to the binding of a galectin, such as galectin-1 to a ligand in a mammal, such as a human. Furthermore, the present invention concerns a method for treatment of a disorder relating to the binding of a galectin, such as galectin-1 to a ligand in a mammal, such as a human.
inline infrared spectroscopy revealing unexpected results particularly concerning the reaction order (zero-order process). With regard to safety, selectivity, and up-scaling a flow-chemistry procedure for the TRF reaction has been developed. Finally, the technological relevance of the ene-yne structural motif is extended by a new design concept for NLO-chromophores showing the highest second harmonic generation

single-crystal X-ray diffraction, and cyclic voltammetry. Notable dye properties include largeStokesshifts (>100 nm), pronounced solvatofluorochromic effects arising from intramolecularchargetransfer, moderate fluorescencequantumyields in both solutions and thin films, and extensive supramolecular C–H···F interactions in their crystalline states. Reversible mechanofluorochromism was also observed in dye

The synthesis of unsymmetrical 2,5-disubstituted thiophenes by selective and sequential palladium-catalyzed cross-couplingreactions of indiumorganometallics with 2,5-dibromothiophene is reported. Following an iterative coupling sequence, α-oligothiophenes were synthesized in good yields and with high atom economy.

Three novel ethyne-linked donor/acceptor chromophores, BAB, BAS and SAS were synthesized. The results of BAB in femtosecond and nanosecond Z-scan at 532 nm reveal that the transition from saturable absorption (SA) to reverse saturable absorption (RSA), while that of BAS and SAS display RSA. The femtosecond Z-scan results for all compounds at 600 nm–800 nm indicate the obvious RSA, which can be mainly
