| Abstract: | In termolecular excimer formation of polyethersulphone (PES) with rigid chain in CH2Cl2 was studied in detail by fluorescence emission spectra. The mechanism of intermole-cular excimer formation was also discussed. The results obtained are:1.The intramolecular excimer of PES in CH2Cl2 can not be formed in normal case because it is rigid chain polymer with aromatic ring on its main chain.2.In very dilute CH2Cl2 solution of PES (below 4.4×10-4M), both of the intermole-cular and intramolecular excimers can not be formed. 3. The intermolecular excimer of PES in CH2Cl2 can be formed when its concentration reach more than 4.4×10-4M. |
