Synthesis And Optoelectronic Properties Of An Anthracene Derivative

Organic single-crystalline micro-and nanostructures synthesized from?-conjugated molecules have attracted particular interest as building blocks for optoelectronic devices such as field-effect transistors,photoswitches,and complementary inverters.Compared to organic thin films,single crystals can show intrinsic charge-transport properties and high mobility,owing to the absence of grain boundaries and minimized concentration of charge traps.They provide the opportunity to elucidate the relationship between microscopic molecular packing and macroscopic charge transport for the design of new semiconductor materials with high performance.Anthracene derivatives are found as promising OSC besides offering a solution-based process.An Anthracene derivative,(2-(4(-2Ethyloctyl)Phenyl)6Phenyl Anthracene(EOPPA),was successfully synthesized with four simple steps with good yields.The EOPPA compound was determined as a durable high performing semiconductor with thin-film device mobility over 0.18 cm²V^-1s^-1.The design and synthesis of EOPPA as a highly asymmetric structural feature enables the preparation of two-dimensional single-crystalline thin films in micrometer-sized and 100 nm thickness by the solution processing method directly on the Si/Si O2 substrate.The efficient solution processing synthesis of EOPPA and the low performance indicates as having great potential in organic electronics.The conducted physicochemical properties measurements of EOPPA verify of its thermal stability through TGA analysis.The decomposition temperature was determined as over 253 ^oC and EOPPA UV-vis absorption spectrum in solution was 400nm.The HOMO measurement and calculation of EOPPA through the Cyclic-voltammetry technique is about-5.138 beside it is much soluble compared to DPA(Di Phenyl Anthracene).
