A photochromic platinum(II) bis(alkynyl) complex containing a versatile 5,6-dithienyl-1,10-phenanthroline

A luminescent diarylethene-functionalized platinum(II) diimine bis(alkynyl) complex displays interesting photochromic behavior with successful photosensitization by excitation into the (MLCT)-M-3/LLCT excited state of this complex to trigger photocyclization.
