Extended π‐Conjugation and Structural Planarity Effects of Symmetrical D‐π‐A‐π‐D Naphthalene and Perylene Diimide Semiconductors on n‐type Electrical Properties
Abstract:A series of donor‐π‐acceptor‐π‐donor (D‐π‐A‐π‐D) compounds based on naphthalendiimide (NDI) and perylenediimide (PDI) central cores combined with triphenylamine and phenylcarbazole donor groups have been synthesized, characterized and tested in top‐contact/bottom gate organic field‐effect transistors (OFETs). The results showed high electron mobilities, up to 0.3 cm2 V−1 s−1, in the case of NDI derivatives and moderate values of around 10−3 cm2 V−1 s−1 for PDI‐based semiconductors.

“…26–30 On the other hand, the covalent linkage of naphthalimide units with strong donor scaffolds such as oligothiophenes or triarylamines has shown to be a promising approach to obtain ambipolar materials. 31,32 Thus, in our research groups we have widely demonstrated that the combination of donor and acceptor units through different rigid and conjugated linkers can pave the way to functional materials with tunable and, sometimes unexpected, optical and electrochemical properties and good n-type or ambipolar characteristics in OFETs or OSCs. 33–40…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
