采用核磁共振波谱法研究了一烷基二吡咯甲烷与乙酸锌的络合反应。在滴定条件下观察到一种中间体，指定为异电性锌（二吡咯烷）（醋酸酯）络合物，尽管在简单的反应后只得到锌（二吡咯烷）(2)。这表明歧化发生在加工过程中，二吡咯甲烷络合在自组装控制下不发生。
H-1 NMR spectroscopy has been used to study the complexation of a per-alkyl dipyrromethene with zinc acetate. An intermediate, assigned to be the heteroleptic Zn(dipyrromethene) (acetate) complex, is observed under titration conditions although only zinc(dipyrromethene)(2) is obtained after simple work-up. This indicates that disproportionation occurs during work-up and that dipyrromethene complexation does not occur under self-assembled control.
