Problems solved by technology

The traditional compounding of thiophene and silicate is mostly thiophene derivatives. With the deepening of research, researchers have found that thiophene derivatives increase the steric hindrance due to the introduction of substituents, which indirectly leads to the fact that thiophene polymerization often shows no order, leading to a decrease in the conductivity of the material; on the other hand, organic solvents are toxic, and most of the chloroform after the reaction evaporates, causing serious pollution to personnel and air.
