Ester Flanked Functionalized Quinolines Design Synthesis and Application in Unipolar and Ambipolar Organic Field Effect Transistors

Abstract

Transistors are important components of integrated circuits that are present in the majority of modern electronic equipments. Enormous attempts have been devoted to improving the chemical stability, charge-transporting properties of the active layer. Heteroacenes have proven to be an important class of fused aromatic compounds due to their many advantages like planar and#960;-conjugated structure which provides extended conjugation length and eliminates the conformational disorder to improve the charge-carrier passage and many more. Quinoline is a fused pi-conjugated aromatic compound with a large overlapping area which is advantageous for good charge-carrier properties. It is a versatile molecule due to many important properties like easier synthesis, purification, well-defined molecular structures, better film-forming property, and batch-to-batch reproducibility which makes them a suitable applicant to be used as organic semiconducting materials. With bottom-up molecular engineering, we can tune its electronic properties for better device performance. The Donor-Acceptor system (D-A) was largely explored and exhibits promising results, but other molecular architects are also being expansively explored.
