Abstract:
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, A wherein in structure 5 A wherein T is selected from the group consisting of CR wherein structure 7 comprises one or more bridging linkages selected from the group consisting of Z, Z 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, NR R the organic material to be doped has a reduction potential vs. Fc/Fc wherein no hydrogen or Lewis acid is released upon cleavage.
