摘要：

Low energy losses due to non-radiative decay are an important step towards high-efficiency organic LEDs. The rigid, regioregular structure of the novel ladder poly(p-phenylene)s reported here lead to a reduction in such losses and to potentially interesting internal LED efficiencies of 1%. The effect on the efficiency of varying the length of the spacers in the structure is examined.
