Fluorescence spectra for the microcrystals and thin films of trans,trans,trans-1,6-diphenyl-1,3,5-hexantrienes
Article Abstract:
The absorption and fluorescence spectra, fluorescence quantum yields and lifetimes for the microcrystals and vacuum deposited thin films of the p,p'-disubstituted trans,trans,trans-1,6-diphenyl-1,3,5-hexatrienes (DPHs) 1-10 are measured and compared with those in dilute solutions at room temperature and in organic glasses at 77K. The broad fluorescence observed for the diformyl derivative (6) is assigned to excimer emission.

Crystal structure of friction-transferred poly(2,5-dioctyloxy-1,4-phenylenevinylene)
Article Abstract:
A backbone aligned thin poly(2,5-dioctyloxy-1,4-phenylenevinylene) (DOPPV) film on substrate is obtained by the fraction-transferred method from a compressed polymer powder block. The results have shown that the DOPPV molecules in friction-transferred film are perfectly arranged three-dimensionally and two neighboring DOPV molecules along the direction of inter-backbones are shifted with respect to one another.

Insertion of thin interlayers under the negative electrode of C60 Schottky-type photovoltaic cells
Article Abstract:
The influence of the insertion of thin metallic layer for C60 Schottky-type solar cells is discussed. It is concluded that the alkaline-earth Mg plays an important role in the improvement of electron transportation in the C60 layer.
