Abstract
In a novel electron-donor-acceptor conjugate, phthalocyanine (Pc) and perylenediimide (PDI) are connected through a trans-platinum(II) diacetylide linker to yield Pc-Pt-PDI1. In the ground state, the presence of Pt disrupts the electronic communication between the two electroactive components, as revealed by UV/Vis spectroscopy and electrochemical studies. The photophysical behavior of 1 is compared with that of the corresponding Pc-PDI electron-donor-acceptor conjugate2 in terms of charge separation and charge recombination. The insertion of Pt between Pc and PDI impacts the results in a longer-lived Pc/PDI radical ion-pair state. In addition, the intermediately formed Pc triplet excited state is formed with higher quantum yields in 1 than in 2. Linked up: The photophysical behavior of a phthalocyanine (Pc)-perylenediimide (PDI) Pc-Pt-PDI donor-acceptor hybrid (see figure), in which a platinum diacetylide linker disrupts electronic communication between the two electroactive components, is compared with that of the corresponding conjugated Pc-PDI array in terms of photoinduced generation of a long-lived charge-separation state.
