“…In order to establish a better donor–acceptor system to generate long-lived charge-separated states, the photoinduced charge transfer of organic heterojunctions formed by the combination of two donors and an acceptor under the action of an external electric field is simulated. The heterojunction formed by the donor–acceptor combination was TPA-TT-BODIPY-C 60 , where triphenylamine (TPA)-terthiophene (TT) was the first donor and BF 2 -boron dipyrromethene (BODIPY) was the second donor . BODIPY, a popular choice for optoelectronic materials, can easily change its spectral and photophysical properties with minor modifications to the structure.…”

As a bridge between C 60 and TPA-TT, BODIPY helps to increase the light absorption range and is a good promoter of charge transfer.…”

Focusing on the photoinduced electron transfer properties of the D-D-A molecule ((TPA-TT)-BODIPY-C 60 ) in an external electric field (F ext ), the excited-state properties in which the double-donor molecule is excited to form three chargeseparated states were simulated. The charge-transfer processes of these three charge-separated states were investigated by considering the two donors as a whole ((TPA-TT-BODIPY)• + -C 60 • − ) as a comparison object. The electronic coupling (V DA ), reorganization energy (λ), and free energy (ΔG) of the different charge-separated states in F ext were calculated and simulated. The calculated results show that the λ of (TPA-TT-BODIPY)• + -C 60 • − ranges from 0.576 to 0.51 eV, and the calculated ΔG of exciton dissociation ranges from −1.402 to −1.143 eV, indicating that exciton dissociation occurs in the Marcus inverted region. In the range of F ext = −10 × 10 −5 to 10 × 10 −5 au, the trend of the charge-transfer rate is gradually increasing, and the rate increase is mainly from the V DA and ΔG changes. Moreover, the rapid formation of the (TPA-TT)-BODIPY• + -C 60 • − charge-separated state and the formation of the long-lived (TPA-TT)• + -BODIPY-C 60 • − are indicated by the exciton dissociation rate. By studying the charge-transfer parameters under different electric field directions, it is found that the regulation of electric field strength on the charge-transfer rate is consistent. These results provide a feasible method for the rational design of a new type of electron transfer process with high efficiency of the D-D-A system.

“…1), in which triphenylamine (TPA)-tertithiophene (TT) is the rst donor and BODIPY is the second donor. 26 So far, fullerenes and their derivatives have become promising materials for DSSCs, and the insertion of BODIPY provides a bridge between TPA-TT and fullerenes for efficient charge transfer, which is a good charge transfer promoter. 27,28 The formed dualdonor structure can break the light absorption limitation of the D-A system and increase the charge transfer path, thus improving the efficiency of the cell device.…”
