Photoinduced Cascading Charge Transfer in Perylene Bisimide-Based Triads

Abstract: We synthesize three perylene bisimide-based triads with donor−acceptor−acceptor (D∼A 1 −A 2 ) architectures, in which the distance between D and A 1 is varied to study its influence on the excited state electron processes. Very different intramolecular charge transfer (D + ∼A 1 −A 2 − ) lifetimes in dichloromethane (DCM) for these three triads are revealed by steady-state and transient spectroscopies. Free-energy changes of charge transfer (CT) are calculated based on the single-crystal X-ray diffraction data … Show more

“…Even for this mostly self-directed learning experience, we provide two stages of guidance . The first stage is to assist students in their design process by providing reading materials containing information related to the organic small molecules. ,, The second stage is to engage in conversations concerning current research activities involving organic small molecules, such as their involvement in energy transfer of orgnisms, various designs of small organic molecules, studies of mechanisms/properties for solar cell technology, , the effects of aggregation of molecules on the kinetics , and performance of technology, , and discussions concerning the advantages of using a combination of different experimental and computational approaches . Furthermore, the TA also answers any emergent questions and discusses with students any issues they may have regarding the content of their weekly journal reading.…”

“…To understand these details, molecular triads that combine electron‐donating and accepting parts in one molecule [ 24–26 ] can be used as models for the photo‐induced transfer of electrons as studied by Meyer et al as well as Sakai et al for phenothiazine‐based triads. [ 27,28 ]…”

“…To understand these details, molecular triads that combine electron-donating and accepting parts in one molecule [24][25][26] can be used as models for the photo-induced transfer of electrons as studied by Meyer et al as well as Sakai et al for phenothiazine-based triads. [27,28] Especially if short distances between donor and acceptor are involved, charge recombination is always competing electron transfer.…”
