A new highly soluble platinum porphyrin derivative 10 with suppressed photobleaching is prepared on a multigram scale from inexpensive starting materials. 10 possesses intense absorption bands at λ = 463 nm (log ε = 5.39) and 633 nm (log ε = 5.20) with near-IR emission at 755 nm. Efficient NIR phosphorescence (PLQY = 0.45) and a large Stokes shift (eliminating self-absorption) make it an attractive
