Abstractp-Terphenyl (TP) nanocrystals with different sizes from 50 to 300 nm were prepared by the reprecipitation method. Their main absorption peaks attributed to L-1(a) <-- (1)A transition were observed to shift to longer wavelength region with increasing crystal size, At the same time, a new peak assigned to L-1(b) <-- (1)A absorption emerged and became stronger. This size-dependent property of the absorption spectra may be attributed to the interaction between TP molecules. The fluorescence excitation spectra of TP nanocrystals also exhibited size-dependent properties, as well as absorption spectra, and the difference between the emission spectra of TP monomer and those of TP nanocrystals may result from different configuration of the TP molecules in the two states.
