    • Provided is a method for preparing polythiophene nanoparticles and derivatives thereof, wherein the polythiophene nanoparticles and derivatives thereof have good processability and exhibit particle luminescence characteristics ranging from blue to red color in an aqueous phase according to a production process. The method for preparing polythiophene nanoparticles and derivatives thereof comprises the steps of: (1) adding thiophene or derivatives thereof, 25-55wt%, based on the weight of the thiophene or derivatives thereof, of an emulsifier, and 50-1000wt%, based on the weight of the thiophene or derivatives thereof, of a first oxidizer to 1000-1300wt%, based on the weight of the thiophene or derivatives thereof, of an acidic solution having a temperature of 20-50‹C and pH of 1-5, and mixing the admixture to prepare emulsion; (2) mixing the prepared emulsion with 0.1-10wt%, based on the weight of the thiophene or derivatives thereof, of a second oxidizer as an initiator, followed by stirring the mixture at 45-55‹C for 10-30 minutes to prepare seed emulsion; and (3) stirring the prepared seed emulsion at 50-55‹C for 6-12 hours to perform emulsion oxidation polymerization.
