Eight different methods of fluorographic enhancement of sensitivity to 35S decay after gel electrophoresis were compared. Using Kodak X-Omat AR X-ray film, we found that some fluors were about equivalent to 2,5-diphenyloxazole/dimethyl sulfoxide embedding, whereas several other fluors were not

Spectral and time-resolved fluorescence properties as well as relative fluorescence quantum yields of carbodiimide derivatives of 2.5-diphenyloxazole (PPO) (prepared by H2S elimination from the corresponding thioureas), of some intermediates in the preparation, and of several other PPO derivatives were investigated

We present a femtosecond broad-band fluorescence up-conversion study of the vibrational relaxation dynamics of two UV chromophores, 2,5-diphenyloxazole (PPO) and para-terphenyl (pTP), pumped with a large excess of vibrational energy (>2000 cm(-1)). The band narrowing of the transient fluorescence spectrum

A series of luminescent platinum(II) alkynyl complexes containing 2,5-diphenyl-1,3,4-oxadiazole (oxa-2,5) and 10,15-dihydro-5H-diindeno[1,2-a;1',2'-c]fluorene (truxene) as the cores and different electron donors at the periphery has been synthesized and characterized. These complexes showed long-lived emissions in both solution and in the solid

Molecular states of 2,5-diphenyloxazole (PPO) were investigated in ground mixtures with gamma-cyclodextrin (gamma-CD). Crystalline PPO gradually became amorphous upon grinding in the presence of gamma-CD. Solid-state fluorescence spectra of the ground mixtures showed that the fluorescence emission peak due to
