1. A method for preparing doped organic semiconductor materials comprising the following steps:
(i) preparing a solution or suspension comprising at least one dopant precursor, at least one organic material to be doped, and a solvent, (ii) applying the solution or suspension onto a substrate and removing the solvent, and (iii) converting the dopant precursor into a dopant by application of activation energy, wherein the dopant precursor is a dimer, oligomer, polymer, dispiro compound, or polycycle of the dopant into which the dopant precursor is cleaved by application of activation energy, wherein the difference between the oxidation potential of the dopant precursor and reduction potential of the organic material to be doped is greater than 0.05 V, and wherein the dopant is selected from the group consisting of: wherein structure 3 comprises one or more cyclic linkages selected from the group consisting of A, A1, and A2, wherein A, A1, and A2, independent of each other, comprise, substituted or unsubstituted, carbocyclic, heterocyclic, or polycyclic ring systems; wherein in structure 5 Al and A2 are present alone or together and are as defined above, wherein T is selected from the group consisting of CR22, CR22R23, N, NR21, O, and S; wherein structure 7 comprises one or more bridging linkages selected from the group consisting of Z, Z1, and Z2, and wherein Z, Z1, and Z2 are independently selected from alkyl, alkenyl, alkynyl, cycloalkyl, sililyl, alkylsililyl, diazo, disulfide, heterocycloalkyl, heterocyclyl, piperazinyl, dialkylether, polyether, primary alkyl amine, arylamine and polyamine, aryl, or and heteroaryl; wherein in structures 8a-8c the ring per heterocycle comprises from 5 to 7 atoms, wherein X and Y are independently selected from the group consisting of O, S, N, NR21, P, and PR21; and R0-18, R21, R22, and R23 are independently selected from, substituted or unsubstituted, aryl, heteroaryl, heterocyclyl, diarylamine, diheteroarylamine, dialkyl amine, heteroarylalkylamine, arylalkylamine, H, F, cycloalkyl, halogencycloalkyl, heterocycloalkyl, alkyl, alkenyl, alkynyl, trialkylsilyl, triarylsilyl, halogen, styryl, alkoxy, aryloxy, thioalkoxy, thioaryloxy, sililyl, trialkylsilylalkynyl, or a (hetero)aliphatic or y, (hetero)aromatic ring system, wherein the (hetero)aliphatic or (hetero)aromatic ring system comprises one or more of R0-l8, R21, R22, and R23, the organic material to be doped has a reduction potential vs. Fc/Fc+that is more negative than −1.0 V, and wherein no hydrogen or Lewis acid is released upon cleavage. |
