A Distannylated Monomer of a Strong Electron‐Accepting Organoboron Building Block: Enabling Acceptor–Acceptor‐Type Conjugated Polymers for n‐Type Thermoelectric Applications

Angewandte Chemie International Edition, Год журнала: 2021, Номер 60(29), С. 16184 - 16190

Опубликована: Май 7, 2021

Abstract Acceptor–acceptor (A‐A) copolymerization is an effective strategy to develop high‐performance n‐type conjugated polymers. However, the development of A‐A type polymers challenging due synthetic difficulty. Herein, a distannylated monomer strong electron‐deficient double B←N bridged bipyridine (BNBP) unit readily synthesized and used by Stille polycondensation. The resulting show ultralow LUMO energy levels −4.4 eV, which among lowest value reported for organoboron After n‐doping, exhibit electric conductivity 7.8 S cm −1 power factor 24.8 μW m K −2 . This performance best polymer thermoelectric materials. These results demonstrate great potential thermoelectrics.

ConspectusMolecular doping is one of the most central propositions in field organic electronics. Unlike classical inorganic semiconductors doped by atomic substitution, conjugated materials react with molecular dopants, and then intermolecular charge transfer involved within. Therefore, complex noncovalent interactions between two components often cause dopant to destroy orderly stacking host reduce original properties material, such as carrier mobility, which here we call "doping dilemma." Recently, many studies focus on improving p-doping efficiency electrical conductivity polymers; however, development n-type currently lags far behind that its p-counterpart.
