Fluorescent conjugated polymers containing semi-ladder units for light-emitting field-effect transistors

Materials are provided for use as active emissive layers in organic electronic devices such as light-emitting filed effect transistors. Light-emitting transistors (LET) are an alternative to light-emitting diodes and have several important benefits, however, materials developed specifically for LET are quite scarce. Herein a new family of materials is disclosed that has been developed specifically for LET.
