Chem. doping is a key process for investigating charge transport in organic semiconductors and improving certain (opto)electronic devices1-9. N(electron)-doping is fundamentally more challenging than p(hole)-doping and typically achieves a very low doping efficiency (η) of less than 10%1,10. An efficient mol. n-dopant should simultaneously exhibit a high reducing power and air stability for broad applicability1,5,6,9,11, which is very challenging. Here we show a general concept of catalyzed n-doping of organic semiconductors using air-stable precursor-type mol. dopants. Incorporation of a transition metal (for example, Pt, Au, Pd) as vapor-deposited nanoparticles or solution-processable organometallic complexes (for example, Pd2(dba)3) catalyzes the reaction, as assessed by exptl. and theor. evidence, enabling greatly increased η in a much shorter doping time and high elec. conductivities (above 100 S cm-1; reference 12). This methodol. has technol. implications for realizing improved semiconductor devices and offers a broad exploration space of ternary systems comprising catalysts, mol. dopants and semiconductors, thus opening new opportunities in n-doping research and applications12, 13.Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Related Products of 51364-51-3) was used in this study.
Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3) is the most widely used PdO precursor complex in synthesis and catalysis, in particular as a catalyst for various coupling reactions. Related Products of 51364-51-3 It is used as a catalyst precursor for palladium-catalyzed carbon-nitrogen bond formation, conversion of aryl chlorides, triflates and nonaflates to nitroaromatics.
