CAS.187275-76-9 3-bromo-3′-iodo-1,1′-biphenyl

This compound consists of two benzene rings and has two halogen substituents, iodine and bromine. Its conjugated structure provides excellent electronic properties, making it promising for the synthesis of OLED materials. Among them, the conjugation property of 3-iodo-3 ‘- bromobiphenyl gives it good regulatory ability in band structure. By adjusting the position and properties of substituents, the electron and hole energy levels can be optimized, thereby improving the current efficiency and luminescence characteristics of OLEDs. In addition, the structure of the compound enables it to effectively transport holes. Its hole energy level can be adjusted through chemical modification to enhance its transport efficiency in the luminescent layer. This characteristic makes it particularly important as a hole transport material.
