おPhenylenediimido cellulose,displayed the fluorescence emission at 555nm with the exciting wavelength at 470nm at room temperature,has been synthesized by ophenylenediamine and dialdehyde cellulose.The product is stable in solution of HCl(1∶1) but is easily soluble in organic solvent,such as EtOH,MeOH,CH3COCH3 etc.Considering ophenylenediimido cellulose is a kind of schiff′s base,we found that as pH of the system is in the range from 6.8 to 13,the reaction occures predominantly,if however,the secondary reactions by polymerization of ophenylenediaimine and crosslinking reaction of dialdehyde cellulose are taken away ophenylenediamine polymerization would be accelerated.The thermal properties and structural characters of the product were described based on the results of DSC and that of FTIR Spectra.
