High mobility n-channel single-crystal field-effect transistors based on 5,7,12,14-tetrachloro-6,13-diazapentacene

Abstract

Heteroaromatic oligomer 5,7,12,14-tetrachloro-6,13-diazapentacene (TCDAP) was characterized and assessed as n-channel material in field-effect transistor applications. A single-crystal transistor based on TCDAP as the channel material exhibits a very high electron mobility of 3.39 cm(2) V(-1) s(-1) and an on/off ratio of ∼1.08 × 10(4) respectively.

Molecular Semiconductors for Logic Operations: Dead‐End or Bright Future?

“…Morphology of polycrystalline thin films deposited either from solution or vapor, and their subsequent characterization have been reviewed, at several occasions. Interested readers are directed toward existing literature …”

Self-assembly of tetraalkoxydinaphthophenazines in monolayers on HOPG by scanning tunneling microscopy

“…In our recent communication [32] we have reported on a new group of solution processable, electroluminescent organic compounds, namely tetraalkoxydinaphtho[2,3-a:2′,3′-h]phenazines, which extend the family of already reported linear and non-linear azaacenes, widely studied in organic electronics as promising semiconductors [33][34][35][36][37][38]. These derivatives can be obtained from indanthrone-an old alizarin-type insoluble dye-in a relatively simple, one-pot preparation involving the carbonyl group reduction with sodium dithionite followed by the substitution with solubility inducing groups under the phase transfer catalysis conditions [32].…”

Synthesis and Optical Properties of Diaza‐ and Tetraazatetracenes

“…With the advent and promise of organic electronics, this class of compounds has experienced a bit of a "gold rush", and several groups are now researching afresh their synthesis. [3][4][5][6][7][8][9][10][11] Azaacenes promise to be electron-transporting complements of acenes and therefore are of potential importance in organic-electronic applications. A few azaacenes have been successfully utilized as the semiconducting layers in thinfilm transistors, as demonstrated by Miao et al and others.…”

“…A few azaacenes have been successfully utilized as the semiconducting layers in thinfilm transistors, as demonstrated by Miao et al and others. [8][9][10][11] Nevertheless, when compared to other classes of substances, there is a dearth of substituted azaacenes and only few methods for their synthesis. In most cases, the azaacene core was constructed by using the classic condensation of an ortho-quinone (or an aromatic ortho-dihydroxy compound) with an aromatic ortho-diamine.…”
