    Effective interplay of donor and acceptor groups for optoelectronic properties tuning in Oligothiophene-Naphtalimide Assemblies
    (The Royal Society of Chemistry, 2020) Alonso-Navarro, Matías J.; Harbuzarub, Alexandra; de Echegaraya, Paula; Arrechea-Marcos, Iratxe; Harillo-Baños, Albert; de la Peña, Alejandro; Ramos, M. Mar; López Navarrete, J. Teodomiro; Campoy-Quiles, Mariano; Ponce Ortiz, Rocío; Segura, José L.
    In this work, a series of naphthalimide fused thienopyrazine derivatives was designed, and their synthesis and characterization are reported herein. The interaction of this building block with a donor terthiophene fragment laterally substituted by a series of donor and acceptor constituents was analyzed in depth. This strategy was proven to efficiently modulate both the energy and topology of the frontier molecular orbitals involved in the charge transport mechanism. The interplay between the donor and acceptor strengths of the different units composing the material structure is thus essential to efficiently modulate charge carriers and transport properties and to finely tune the optical and electronic structures of the presented organic semiconductors
