摘要: We describe here the synthesis and properties of novel optically active oligophosphines. The effect number chiral phosphorus atoms on thermal conformations is documented. In this study, we captured an intermediate between a polymer small molecule. To best our knowledge, it primarily observed that molecule transforms into via amorphous during process elongation oligomer main chain.
