摘　　要：2,2′,7,7′-Tetrakis(N,N-di-p-methoxyphenyl)-amine-9,9′-spirobifluorene(Spiro-OMeTAD)represents the state-of-the-art hole-transporting material(HTM)in n-i-p perovskite solar cells(PSCs).However,its susceptibility to stability issues has been a long-standing concern.In this study,we embark on a comprehensive exploration of the untapped potential within the family of spiro-type HTMs using an innovative anisotropic regulation strategy.Diverging from conventional approaches that can only modify spirobifluorene with single functional group,this approach allows us to independently tailor the two orthogonal components of the spiro-skeleton at the molecular level.
