Heteroatomic hole transport materials are provided. The hole transport materials include a non-carbon core: two, four, or eight aromatic groups covalently bound to the non-carbon core; a. terminal substituted diphenylamine end unit on each aromatic group: and optionally aromatic linker groups linking the aromatic groups and the substituted diphenylamine end units. In some embodiments the non-carbon core is non-carbon central atom such as Si, Ge, B.sup., P.sup.+Sn or Pb. In other embodiments, the non-carbon core is a cubic silsesquioxane. Also provided are methods for making these materials. The materials are particularly useful as hole transport materials in perovskite solar cells.

The present invention relates to new phosphaviologen derivatives, methods of making phosphaviologen derivatives, and uses thereof, including uses in electrochromic devices and organic battery materials. The phosphaviologen derivatives described herein have strong electron-accepting properties and can be used to provide phosphaviologen derivative-containing electronic materials. In certain embodiments, the phosphaviologen derivatives include dimeric phosphaviologens.
