Development of typical-element-doped functional π systems consisting of naphthalene monoimide units

Abstract

The function of 
these compounds is closely related tontheir delocalized π-electrons, which can be precisely modulated by introducing 
functional groups on the periphery of the compound. The characteristics of such designed molecules strongly rely on 
the inherent electronic nature of the parent skeleton, highlighting the importance of selecting an appropriate motif 
molecule. Such π-conjugated molecules should satisfy two criteria: (1) they intrinsically exhibit desirable electronic 
properties and (2) their structures are readily transformable via well-established organic transformations. π-Conjugated 
molecules are intrinsically electrondonors because the π-electrons are loosely bound to the core.
