The phosphorus atom in these molecules has unusual properties, in particular changing its affinity as an electron acceptor when exposed to certain wavelengths of light. This makes phosphaphenalenes useful in optoelectronic applications such as temperature-dependent luminescence and electrochromism (reversibly changes colour when electricity is applied).[2][3] References1. ^{{cite journal|last1 = Trujillo|first1 = Cristina|last2 = Sánchez-Sanz|first2 = Goar|last3 = Alkorta|first3 = Ibon|last4 = Elguero|first4 = José|authorlink4 = José Elguero Bertolini|title = An insight on the aromatic changes in closed shell icosagen, tetrel, and pnictogen phenalenyl derivatives|journal = Struct.
