Fundamental discoveries in electron transfer advance scientific and technological advancements. It is suggested that in plant and bacterial photosynthesis, the primary donor, a chlorophyll or bacteriochlorophyll dimer, forms an initial excited symmetry‐breaking charge transfer state (1CT*) upon photoexcitation that subsequently promotes sequential electron transfer (ET) events. This is unlike monomeric photosensitizer‐bearing donor‐acceptor dyads where ET occurs from the excited donor or acceptor (1D* or1A*). In the present study, we successfully demonstrated the former photochemical event using an excited charge transfer molecule as a donor. Electron‐deficient perylenediimide (PDI) is functionalized with three electron‐rich piperidine entities at the bay positions, resulting in a far‐red emitting CT molecule (DCT). Further, this molecule is covalently linked to another PDI (APDI) carrying no substituents at the bay positions, resulting in wide‐band capturing DCT‐APDIconjugates. Selective excitation of the CT band of DCTin these conjugates leads to an initial1DCT* that undergoes subsequent ET involving APDI,resulting in DCT

Abstract + ‐APDI−charge separation product (k CS~109 s−1). Conversely, when APDIwas directly excited, ultrafast energy transfer (ENT) from1APDI* to DCT(k ENT~1011 s−1) followed by ET from1DCT* to PDI is witnessed. While increasing solvent polarity improvedk CSrates, for a given solvent, the magnitude of thek CSvalues was almost the same, irrespective of the excitation wavelengths. The present findings demonstrate ET from an initial CT state to an acceptor is key to understanding the intricate ET events in complex natural and bacterial photosynthetic systems possessing multiple redox‐ and photoactive entities. -

Abstract We report on the largest open‐shell graphenic bilayer and also the first example of triply negatively charged radical π‐dimer. Upon three‐electron reduction, bilayer nanographene fragment molecule (C96H24Ar6)2(Ar=2,6‐dimethylphenyl) (
1 2) was transformed to a triply negatively charged species1 23.−, which has been characterized by single‐crystal X‐ray diffraction, electron paramagnetic resonance (EPR) spectroscopy and magnetic properties on a superconducting quantum interference device (SQUID).1 23.−features a 96‐center‐3‐electron (96c /3e ) pancake bond with a doublet ground state, which can be thermally excited to a quartet state. It consists of 34 π‐fused rings with 96 conjugatedsp 2carbon atoms. Spin frustration is observed with the frustration parameterf >31.8 at low temperatures in1 23.−, which indicates graphene upon reduction doping may behave as a quantum spin liquid. -

Abstract In multichromophore systems, characterization of electronic structure requires characterization of exciplexes, electron‐hole pairs delocalized over multiple molecules. Computing exciplex binding energy requires an accurate description of both the noncovalent interactions between the chromophores and their excited electronic states. The critical role of basis set selection for accurate description of noncovalent interactions is well known, but for some of the most accurate excited‐state methods, basis set dependence is incompletely understood. In this work, the impact of basis set size and diffuseness on CASSCF/NEVPT2 binding energies is determined for three systems in their lowest singlet excited states: the benzene excimer, the
cis ‐butadiene‐benzene exciplex, and the benzene‐naphthalene exciplex. We demonstrate that excellent CBS binding energies may be obtained using the moderately‐sized jun‐cc‐pV(D + d)Z and jun‐cc‐pV(T + d)Z basis sets and a simpleN−3 model. Repeating this procedure with theN = 3, 4 basis sets from the most diffuse basis set family applied to each system yields a binding energy of 56.6 ± 1.2 kJ/mol for the benzene excimer and binding energies of 11.1 ± 0.5 kJ/mol and 19.2 ± 1.7 kJ/mol for thecis ‐butadiene‐benzene exciplex and the benzene‐naphthalene exciplex, respectively. -

Abstract The use of polar solvents MeCN or dimethylformamide (DMF) was previously shown to induce a selectivity switch in the Pd/P
t Bu3‐catalyzed Suzuki‐Miyaura coupling of chloroaryl triflates. This phenomenon was attributed to the ability of polar solvents to stabilize anionic transition states for oxidative addition. However, we demonstrate that selectivity in this reaction does not trend with solvent dielectic constant. Unlike MeCN and DMF, water, alcohols, and several polar aprotic solvents such as MeNO2, acetone, and propylene carbonate provide the same selectivity as nonpolar solvents. These results indicate that the role of solvent on the selectivity of Suzuki‐Miyaura couplings may be more complex than previously envisioned. Furthermore, this observation has the potential for synthetic value as it greatly broadens the scope of solvents that can be used for chloride‐selective cross coupling of chloroaryl triflates.
