In article no. 1900119 , Zong‐Xiang Xu and co‐workers synthesize isomer‐pure 2,9,16,24‐tetra‐n‐butyl‐Zn (II) phthalocyanine ( RE ‐ZnBu 4 Pc) through ring expanding of symmetric tri‐n‐butyl‐substituted boron subphthalocyanine as a dopant‐free hole transporting material (HTM) in planar conventional perovskite solar cells, which offers higher efficiency, long‐term stability, and reproducibility than HTMs based on ZnBu 4 Pc with an isomer mixture.
