Abstract

<jats:title>Abstract</jats:title><jats:p>An asymmetric a-side alkyl chain anthracene derivative 6-(4 (-2 Ethyl Octyl) Phenyl) 2Phenyl Anthracene (EOPPA) was designed based on a π-electron skeleton with a side alkyl chain of anthracene core molecule. EOPPA was found to be a sturdy and high-performance p-type semiconductor for optoelectronic applications. The creation has successfully made this new material EOPPA with the best solubility, which exhibits both sufficient solvent solubility and thermal stability. The asymmetrical structural features of EOPPA allowed for the preparation of two-dimensional crystalline thin films in micrometer sizes with 100 nm thicknesses on a Si/SiO<jats:sub>2</jats:sub> substrate through a solution processing method. The efficient solution processing synthesis of EOPPA and its high performance suggest that it has great potential in the field of organic electronics. The EOPPA demonstrated optoelectronic properties, crystalline structure, and good thin-film transistors having mobilities higher than 0.18 cm<jats:sup>2</jats:sup> V<jats:sup>−1</jats:sup> S<jats:sup>−1</jats:sup>, and a high current on/off ratio that can withstand temperatures of almost 225 °C. Furthermore, EOPPA presents good potential to be amongst the next generation of p-type anthracene core organic semiconductors, especially for practical printed electronics applications.</jats:p>
