Synthetic tools and reagents are necessary to scientific researches. The accuracy and stability of the synthetic tools will affect the stability of the experimental process, and then affect the performance of the product. Furthermore, the quality of the reagents also an important factor for an experiment. For example, if the reagent purity is low, on the one hand, the reagent itself will bring impurities to the product, and on the other hand, the reaction process will produce more side reactions, which will enhance the separation difficulty and decrease the purity of final product. These phenomena are non-ideal in the process of the experiment. Therefore, before the start of an experiment, it is necessary to have a full understanding of the performance of the synthetic tools and the properties of reagents, so as to ensure the stability and reliability of the experiment.
All scientific research cannot be done without synthetic tools and reagents, especially in organic and printed electronics materials, which is described as below.

According to the applied fields and properties demands of materials, the reagents are different. Depending on the properties of the reactants, different solvents will be chosen. Common solvents are methanol, ethanol, acetone, dichloromethane, trichloromethane, furan, and others. As for reactants, in the organic and printed electronics materials field, common reactants include perylene, squaric acid, coumarin, porphyrin and rhodamine.
