The synthesis and excited-state dynamics are described for a tetrad (ZC - ZP - ZP - I) consisting of zinc chlorin (ZC), zinc porphyrin (ZP), zinc porphyrin (ZP), and pyromellitimide (I), which upon photoexcitation provides a fully charge-separated state (ZC$^+$- P - ZP - l$^- $) with lifetimes of 230 $mu$s in THF and > 50$ mu$s in DMF at room temperature via a stepwise electron-transfer relay that has been detected by the ps-time resolved transient absorption spectroscopy.
