Synthesis and luminescence properties of a series of tris(4-styrylphenyl)phosphorus-(III) and -(V) compounds and of a [Cu (PR3)4]BF4 complex

The series of compounds PR3, O=PR3, MeR3PI, Cl2PR3 and [Cu(PR3)4]BF4(R =(E)-4-(4-tert-butylstyryl)phenyl) has been prepared and optical properties explored by absorption and fluorescence spectroscopy. The effect of geometry and coordination number on luminescence intensity is presented.
