主　　题：Solar perovskite skeleton 

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 *** this study,we embark on a comprehensive exploration of the untapped potential within the family of spiro-type HTMs using an innovative anisotropic regulation *** 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.
