    The syntheses and photophysical properties of novel luminescent polysilanes modified with dansyl fluorophores on various spacer (PMPSi-n-DNS) are reported. Influence of the alkyl chain length (n) on the photophysical properties was investigated using absorption, steady-state, and time-resolved photoluminescence (PL) spectroscopy. The excitation energy transfer from the polysilane backbone to dansyl fluorophore was proved. Polymer light-emitting devices (LEDs) were prepared from the blends of modified polysilane with electroluminescent polymer poly[2,5-dimethoxy-1,4-phenylene-1,2-ethenylene-2-methoxy-5-(2-ethylhexyloxy)-(1,4-phenylene-1,2-ethenylene)] (M3EH-PPV). Compared with LED made of neat electroluminescent polymer, a significant performance improvement of blend LEDs was demonstrated.
