Usage

Uses

Used in Organic Field Effect Transistors (OFETs):
Mo(tfd)3 is used as a dopant in the hole transporting layer of HTM N,N′-di[(1-naphthyl)-N,N′-diphenyl]-1,1′-biphenyl-4,4′-diamine to enhance the performance of organic field effect transistors (OFETs). Its high electron affinity allows for improved charge transport and reduced contact resistance in these devices.
Used in Pentacene-based OFETs:
In the application industry of pentacene-based organic field effect transistors, Mo(tfd)3 is used as a dopant to reduce contact resistance and improve the overall performance of the transistors. Its high electron affinity contributes to better charge transport and device efficiency.

Molybdenum dithiolene complexes as structural models for the active sites of molybdenum(IV) sulfide hydrodesulfurization catalysts

The removal of sulfur (as H2S) from organosulfur species in petroleum feedstocks (hydrodesulfurization, HDS) is carried out on an enormous scale by using heterogeneous catalysts based on MoS2 (usually doped with Co). Partially hydrogenated thiophenes are postulated intermediates in the MoS2-catalyzed hydrodesulfurization of thiophene. The present contribution describes new molecular models for the proposed active sites in HDS catalysis. The models are derived from a mixed-ligand (push-pull) molybdenum trisdithiolene {[Mo(tfd)2(bdt)]; tfd = S2C 2(CF3)2, bdt = S2C6H 4}: selective intraligand alkyne binding converts the bdt group to a labile Mo-chelating benzodithiin, which can be substituted with a variety of weak donor ligands. The complexes [Mo(tfd)2-(dht)2] and [Mo(tfd)2(tht)2] (dht = 2,5-dihydrothiophene; tht =tetrahydrothiophene) were synthesized and crystallographically characterized. The Mo(tfd)2 substructures closely resemble the presumed active site in MoS2 HDS catalysts. The coordination geometries at molybdenum are approximately trigonal prismatic, and the metal bears two strongly bound dithiolene (tfd) groups and two comparatively weakly bound thioether ligands (dht or tht). Competitive binding experiments establish that tht binds more strongly to the Mo center than dht (Keq = 6.5±0.5). Preliminary reactivity studies reveal that [Mo(tfd)2(dht) 2] decomposes to [Mo(tfd)3], thiophene, and unidentified species upon heating. Further, [Mo(tfd)2(tht)2] induces the isomerization of 1,4-cyclohexadiene to 1,3-cyclohexadiene at elevated temperatures.
