Abstract

We report a new p-type dopant, manganese oxide (Mn3O4) nanoparticle, to enhance organic field-effect transistors (OFETs) performance with conjugated polymers including poly(3-hexylthiophene-2,5-diyl); poly[[N,N 9-bis(2-octyldodecyl)- naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,59-(2,29-bithiophene)]; and poly[[2,5-bis(2-octyldodecyl)-2,3,5,6-tetrahydro-3,6-dioxopyrrolo[3,4-c]pyrrole-1,4-diyl]-alt-[[2,2'-(2,5-thiophene)bis-thieno(3,2b) thiophene] -5,5'-diyl]] (DPPT-TT). Incorporating a small amount of Mn3O4 nanoparticle in the semiconductor film significantly improved hole mobility and decreased threshold voltage for all OFETs, indicating efficient Mn3O4 nanoparticle p-type doping. The Mn3O4 nanoparticle showed better doping efficiency than the widely used FeCl3 dopant due to better mixability with host conjugated polymers. In particular, doped DPPT-TT OFETs showed significantly improved mobility up to 2.35 (± 0.4) cm2/V·s with enhanced air and operational stability at 0.1 wt% doping concentration from 1.2 cm2/V·s for pristine devices.

Manganese Bohr ModelThe number of electrons in each of Manganese's shells is [2, 8, 13, 2] and its electron configuration is [Ar] 3d5 4s2. The manganese atom has a radius of 127 pm and a Van der Waals radius of 197 pm. Manganese was first discovered by Torbern Olof Bergman in 1770 and first isolated by Johann Gottlieb Gahn in 1774. In its elemental form, manganese has a silvery metallic appearance. Elemental ManganeseIt is a paramagnetic metal that oxidizes easily in addition to being very hard and brittle. Manganese is found as a free element in nature and also in the minerals pyrolusite, braunite, psilomelane, and rhodochrosite. The name Manganese originates from the Latin word mangnes, meaning "magnet."
