The heaviest pnictogen-dipyrromethenes DPMPnCl (Pn = Sb, 3; Bi 4), which are direct analogues of boron-dipyrromethene (BODIPY), have been readily prepared and isolated as crystalline solids. Both compounds display green photoluminescence with small full widths at half maximum in toluene. Moreover, the reduction of 3 with sodium metal afforded the cyclic dicoordinate stibinidene 5.
最重的 pnictogen-二吡咯甲川（DPMPnCl，Pn = Sb，3；Bi4），是硼二吡咯甲川（BODIPY）的直接类似物，很容易作为晶体固体进行制备和分离。两种化合物在甲苯中均显示出小的半峰全宽的绿色荧光。此外，用金属钠还原 3 得到了环状二配位的三价锑化合物 5。
