A new class of phosphole oxide based alkynylplatinum(II) 2,6‐bis(N‐alkylbenzimidazol‐2’‐yl)pyridine (bzimpy) complexes were synthesized and characterized. Their self‐assembly was driven by hydrophobic–hydrophobic and π–π stacking interactions. The self‐assembly properties were also investigated by UV/Vis absorption spectroscopy, which revealed that the alkyl‐chain length of the bzimpy moiety and the π‐surface area of the alkynyl ligand have significant influence on the overall self‐assembly process. The alkyl‐chain length also affected the morphological structures of the aggregates, which were studied by transmission electron microscopy and scanning electron microscopy.
