磷杂烯烃（RP=CR2）和二磷杂苯（RP=PR）是烯烃（R2C=CR2）的主族类似物。具有这种多重键合磷官能团的分子通常显示出模仿其纯有机对应物的结构特征和化学反应性，从而使这些化合物是“碳拷贝”的说法变得可信。我们一直在扩展这种类比，以包括具有直接涉及P=C和P=P单元的扩展共轭的低聚物和聚合物。然而，这些材料中的许多材料显示很少或没有光致发光（PL）。本文总结了我们的努力，了解P=C和P=P的光行为，并产生材料具有显着的PL模仿或“影印”的无磷系统的PL性能。最近的材料的基础上苯并oxaphospholes（BOP），苯并bisoxaphospholes（BBOP），和更高的类似物具有显着的荧光量子产率。
Phosphaalkenes (RP=CR2) and diphosphenes (RP=PR) are main group analogues of alkenes (R2C=CR2). Molecules featuring such multiply bonded phosphorus functionalities often display structural features and chemical reactivities that mimic their purely organic counterparts, lending credence to the claim that these compounds are “carbon copies”. We have been expanding this analogy to include oligomers and polymers with extended conjugation that directly involve P=C and P=P units. Many of these materials, however, display little or no photoluminescence (PL). This article summarizes our efforts to understand P=C and P=P photobehavior and to produce materials having significant PL that mimic or “photocopy” the PL properties of the phosphorus-free systems. Recent materials based on benzoxaphospholes (BOPs), benzobisoxaphospholes (BBOPs), and higher analogues having significant fluorescence quantum yields are covered.
