Abstract
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.
Claims20
A semi-ladder, luminescent polymer comprising:
- an electron-accepting organic chromophore selected from the group consisting of thieno [2′,3′ :5,6] pyrido [3,4-g] thieno [3,2-c]-isoquinoline-5,11(4H,10H)-dione (TPTI), 5,11-bis(2-butyloctyl)-dihydrothieno[2′,3′:4,5]pyrido[2,3-g]thieno[3,2-c] quinoline-4,10-dione (TPTQ), and furo[3,2-c]furo[2′,3′:4,5]pyrido[2,3-g]quinoline-4,10-dione (TPTQF);
- and
- an electron-donating co-monomer.
An organic electronic device comprising at least one emissive layer, wherein the at least one emissive layer comprises a semi-ladder, luminescent polymer comprising an electron-accepting organic chromophore and an electron-donating co-monomer.
A multi-layer organic light-emitting transistor comprising:
- at least one dielectric layer;
- at least one self-assembled monolayer;
- and
- at least one emissive layer comprising a semi-ladder, luminescent polymer, wherein the polymer comprises:
- an electron-accepting organic chromophore selected from the group consisting of TPTI (thieno [2′,3′ :5,6] pyrido [3,4-g] thieno [3,2-c]-isoquinoline-5,11(4H,10H)-dione), TPTQ (5,11-bis(2-butyloctyl)-dihydrothieno[2′,3′:4,5]pyrido[2,3-g]thieno[3,2-c] quinoline-4,10-dione), and TPTQF (furo[3,2-c]furo[2′,3′:4,5]pyrido[2,3-g]quinoline-4,10-dione);
- and
- an electron-donating co-monomer selected from the group consisting of carbazole and fluorene.
