Abstract : This invention pertains generally to organic polymers and in particular to organic semiconductors. A semiconductor is a near insulator at room temperature. At this temperature the resistivity of a semiconductor is from ten to the minus 2nd power to ten to the 9th power ohm cm. Until recently organic polymers were generally considered to be very poor conductors of electricity. Newly discovered organic polymers, however, have shown promise as semiconductors. These polymers have the disadvantages of low molecular weight and poor moldability. (Author)
