Functionalization of biphenylcarbazole (CBP) with siloxane-hybrid chains for solvent-free liquid materials

We report herein the synthesis of siloxane-functionalized CBP molecules (4,4′-bis(carbazole)-1,1′-biphenyl) for liquid optoelectronic applications. The room-temperature liquid state is obtained through a convenient functionalization of the molecules with heptamethyltrisiloxane chains via hydrosilylation of alkenyl spacers. The synthesis comprises screening of metal-catalyzed methodologies to introduce alkenyl linkers into carbazoles (Stille and Suzuki Miyaura cross-couplings), incorporate the alkenylcarbazoles to dihalobiphenyls (Ullmann coupling), and finally introduce the siloxane chains. The used conditions allowed the synthesis of the target compounds, despite the high reactivity of the alkenyl moieties bound to π-conjugated systems toward undesired side reactions such as polymerization, isomerization, and hydrogenation. The features of these solvent-free liquid CBP derivatives make them potentially interesting for fluidic optoelectronic applications.

Two methoxyaniline-substituted dibenzofuran derivatives as hole-transport materials for perovskite solar cells

2,2′,7,7′-Tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD), one of the classical organic photoelectric materials, has been widely used as a hole transport material (HTM) in perovskite solar cells (PSCs) due to its relatively higher conductivity, easier film formation, weak absorption in the visible region, etc. However, the complex synthesis process and the high synthesis cost of Spiro-OMeTAD severely limit the commercialization of this material. In this work, two economical methoxyaniline-substituted dibenzofuran derivatives, BF-002 and BF-003, are synthesized and successfully used as hole-transport materials in perovskite solar cells (PSCs). The important properties including light absorption, thermal stability, energy level, conductivity, as well as photovoltaic performance are systematically demonstrated. The highest power conversion efficiencies of the PSCs based on BF-002 and BF-003 are 14.20% and 14.07%, respectively, comparable to that of the PSCs based on Spiro-OMeTAD.
