A general modular route to fluorophore-linked diphosphines from (4-iodophenyl)P(O)Ph(2) is described. The preparation of chromophoric diphosphine (LHP1) proceeded readily using this route. LHP1 was employed to prepare luminescent metallopolymers of platinum (P1) and palladium (P2) exhibiting modest degrees of polymerization (13-14) and extents of polymerization ( approximately 97%). P1 and P2 appear to be the first metallopolymers polymerized via a visible-absorbing/emitting diphosphine. The photophysical properties of these novel materials are discussed.
