New bis(dipyrrinato)zinc(II) complex micro- and nanosheets containing zinc(II) porphyrin (N2) are synthesized. A liquid/liquid interface method between dipyrrin porphyrin ligand L2 and zinc acetate produces N2 with a large domain size. N2 can be layered quantitatively onto a flat substrate by a modified Langmuir-Schäfer method. N2 deposited on a SnO electrode functions as a photoanode for a photoelectric conversion system. The photoresponse of N2 covers the whole visible wavelength range (400-650 nm), with a maximum quantum efficiency of more than twice that of a bis(dipyrrinato)zinc(II) complex nanosheet without porphyrin.
新型含锌(II)卟啉（N2）的双二吡咯并嘧啶锌（II）配合物微纳片被合成。在大尺寸区域内，通过二吡咯啉配体 L2 和乙酸锌之间的液/液界面法生成 N2。通过改进的 Langmuir-Schäfer 方法，N2 可以定量地沉积到一个平坦的基底上。沉积在 SnO 电极上的 N2 可以作为光电转换系统的光阳极。N2 的光响应覆盖整个可见光波长范围（400-650nm），其量子效率最大值是没有卟啉的双二吡咯并嘧啶锌（II）配合物纳米片的两倍多。
