PPP stands for poly (para-phenylene), a linear, stiff-rod polymer made up of p-phenylene units that repeat. PPP's outstanding mechanical, chemical, and thermal qualities make it a great option for a range of high-performance, lightweight applications in the semiconductor, aerospace, and medical sectors. When doped with p and n, it demonstrates electrical conductivity, making it suitable for energy storage. PPP has also been employed as an electroluminescent material while acting as a blue-light emitter (⁁max = 459 nm). PPP synthesis and application, however, continue to be extremely difficult despite these encouraging qualities and uses.
