Synthesis and characterization of a novel polymer based on anthracene moiety for organic thin film transistor

Abstract

We have designed and synthesized a new polymer, which could be used in the organic thin film transistor (OTFT). Poly[2,6‐bis(3′‐dodecythiophene‐2′‐yl)anthracene] (PDTAn), which is composed with anthracene moiety and dodecyl alkyl thiophene, was synthesized by oxidative polymerization using iron (III) chloride. The mole ratio of FeCl3 and monomer (4.2:1), keeping low temperature during the initiation reaction, amount of solvent, and dropping order were very important for oxidative polymerization without crosslinking. The molecular weight of the polymer (Mw) was measured to be 40,000 with 2.85 of polydispersity index by GPC. The physical and optical properties of the polymer were characterized by differential scanning calorimetry (DSC), cyclic voltammetry (CV), and optical absorption and photoluminescence (PL) spectroscopy. A field‐effect mobility of 1.1 × 10−4 cm2 V−1 S−1, a current on/off ratio of 105, and the Vth at −15.2 V had been obtained for OTFTs using this polymer semiconductor by solution coating. © 2008 Wiley Periodicals, Inc.

New anthracene-based semi-conducting polymer analogue of poly(phenylene sulfide): Synthesis and photophysical properties

“…However, the anthracene tends to recrystallize with diode operating time, which led to a degradation of device performance. Recently, the anthracene derivatives represent the most heavily studied and exploited organics semiconductors [14][15][16]; and frequently used in OLEDs [17,18], as well as in other organic thin-layer-based electronic devices such as transistors [19,20] and photovoltaic cells [21,22]. Besides, anthracene is a promising fluorescent building block for highly photoluminescent semi-conducting polymers, which are valuable for the fabrication of stable blue-emitting electroluminescent devices [23].…”
