THIOPHENE MONOMERS OR OLIGOMERS

Due to extended pi-electron cloud overlaps, organometallic molecules or aromatic oligometers such as anthracene exhibit semiconductor properties. Conductive polymers have extended delocalized bonds that creates electrical conductivity when charge carriers generated make positive charges (holes) and negative charges (electrons) move to opposite electrodes. Doping is the intentional impurities in a pure semiconductor to generate charge carriers. The transportation of charges is responsible for fluorescence and electrical energy. These can form well-ordered thin crystalline films. Organic semiconductors have some merits of self radiation, flexibility, light weight, easy fabrication, and low cost. Organic electroluminescence materials have lead to the rapid development of photovoltaic and display devices such as organic solar cells, biosensitizers, OLED(Organic Light Emiting Diode), OTFT(Organic Thin Film Transistor), Wearable Display, and e-Paper. Some examples of organic electroluminescence materials are:

  • Oligomer Electro Luminescence Materials
    • 8-hydroxyquinoline aluminum
    • Anthracene
    • Pentacene
    • Penyl substituent cyclopentadiene derivatives
