title: [Preparation and fluorescence study of anthracene, perylene and 1-aminoanthraquinone colloids].
abstract: Anthracene, perylene and 1-aminoanthraquinone colloids have been prepared by reprecipitation method. In comparison with the fluorescence emission spectra of colloids and molecules (in acetone solution), it was indicated that collids fluorescence spectra are red-shifted and easy emission. Base on the fluorescence emission and molecular structure theory, the authors conclude that these molecules overlap when they form particles. At the same time they are planar molecules. This results in the strong stacking electronic properties. So fluorescence excitation and emission become easy.
