合成了含锌（II）卟啉（N2）的新型双（二吡咯啉）锌（II）配合物微米和纳米片。二吡咯卟啉配体L2和乙酸锌之间的液/液界面方法产生具有大畴尺寸的N2。N2可以通过改进的Langmuir-Schafer方法定量地分层到平坦衬底上。沉积在SnO 2电极上的N2用作光电转换系统的光阳极。N2的光响应覆盖了整个可见光波长范围（400-650 nm），最大量子效率是没有卟啉的双（二吡啉合）锌（II）络合物纳米片的两倍以上。
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-Schafer method. N2 deposited on a SnO2 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.
