We comment on an excited‐state localization method recently proposed by Blanc et al. (J. Comput. Chem. 2023 , 44, 105). Elaborate comparisons are made to demonstrate that their method is a less‐comprehensive version of the diabatization method proposed by us 2 years earlier (J. Phys. Chem. Lett. 2021 , 12, 1032).
A new diabatization scheme is proposed to calculate the electronic couplings for the singlet fission process in multichromophoric systems. In this approach, a robust descriptor that treats single and multiple excitations on an equal footing is adopted to quantify the localization degree of the particle and hole densities of the electronic states. B...

Natural light‐harvesting (LH) systems can divide identical dyes into unequal aggregate states, thereby achieving intelligent “allocation of labor”. From a synthetic point of view, the construction of such kinds of unequal and integrated systems without the help of proteinaceous scaffolding is challenging. Here, we show that four octatetrayne‐bridge...

pH buffer plays versatile roles in both biology and chemistry. In this study, we unravel the critical role of pH buffer in accelerating degradation of the lignin substrate in lignin peroxidase (LiP) using QM/MM MD simulations and the nonadiabatic electron transfer (ET) and proton-coupled electron transfer (PCET) theories. As a key enzyme involved i...
Dipyrrolonaphthyridinedione (DPND) thin films exhibit interesting photophysical properties and singlet fission (SF) processes. A recent experimental work found that the alkyl substitution in the DPND skeleton has the remarkable influence on the characteristics of electronic absorption spectra and SF rates. Here, we theoretically elucidate the micro...

pH plays versatile roles in both biology and chemistry. For instance, pH can regulate the long-range electron transfer (ET) in many proteins. However, the mechanistic basis of many pH-dependent long-range ET processes remain unclear. In this study, we unravel the critical role of pH in accelerating the long-range ET in lignin peroxidase (LiP) using...
A series of new half-disc-shaped platinum(II) complexes [Pt(ppy)(ALn-6OCnH2n+1)] (Pt-An), [Pt(ppyF)(ALn-6OCnH2n+1)] (Pt-Bn), and [Pt(ppyCF3)(ALn-6OCnH2n+1)] (Pt-Cn) (ALn-6OCnH2n+1 = 1,3-bis(3,4,5-trialkoxyphenyl)propane-1,3-dionato; n = 1, 6, 12) with concise structures have been designed and synthesized, in which 2-phenylpyridine (ppy) derivatives...
The vibrationally resolved absorption spectra and ultrafast exciton dynamics in α-phase and β-phase zinc phthalocyanine (ZnPc) aggregates are theoretically investigated using a non-Markovian stochastic Schrödinger equation combined with first-principles calculations. It is found that although similar double-peak structures arise in the Q-band regio...
Radioactive iodine, one type of nuclear waste, is harmful to the environment and human health due to its long half-life and volatility. Therefore, designing and synthesizing low-cost and easily-made materials for the effective adsorption of radioiodine is widely concerned. Herein, a biscuit-shaped new material was synthesized by a grinding-mixing c...
The vibrationally resolved absorption spectra and exciton dynamics in the α-zinc phthalocyanine aggregates are theoretically investigated by using a non-Markovian stochastic Schrödinger equation. The model Hamiltonian adopted for spectral and dynamic simulations explicitly includes the couplings for both nearest-neighbor and remote exciton transfer...
Insightful understanding of the light driven CO2 reduction reaction (CO2RR) mechanism on gold nanoparticles is one of the important issues in the plasmon mediated photocatalytic study. Herein, time-dependent density functional theory and reduced two-state model are adopted to investigate the photoinduced charge transfer in interfaces. According to...
A new scheme is proposed to calculate the electronic couplings for photoinduced charge transfer and excitation energy transfer for both singlet and triplet states. In this scheme, the locally excited and charge-transfer states are constructed from the adiabatic ones by maximally localizing the particle (i.e., electron) and hole densities in terms o...
Long‐range electron transfer (ET) in metalloenzymes is a general and fundamental process governing O2 activation and reduction. Lytic polysaccharide monooxygenases (LPMOs) are key enzymes for the oxidative cleavage of insoluble polysaccharides, but their reduction mechanism by cellobiose dehydrogenase (CDH), one of the most commonly used enzymatic...
The interprotein electron‐transfer (ET) mechanism between lytic polysaccharide monooxygenases (LPMOs) and cellobiose dehydrogenase (CDH) was deciphered by multiscale simulations. Our simulations show that I) the specific ET pathway involves water molecules; II) the long‐range ET is enhanced by exothermic oxygen binding; III) enhanced ET is spin‐reg...
Insightful understanding of bimetallic interfacial effects on catalytic CO2 reduction reaction (CO2RR) is one of the important and challenging issues. Herein, the geometric structure, electronic structure, and electrocatalytic property of Cu(sub-monolayer)/Au bimetallic interfaces are investigated by using the density functional theory calculation....
The vibrationally resolved absorption spectra of zinc phthalocyanine (ZnPc) aggregates (up to 70 monomers) are explored using the non-Markovian stochastic Schrödinger equation. Various types of local excitations, charge-transfer (CT) excitations, and exciton–phonon couplings are explicitly included in a comprehensive model Hamiltonian, which is par...
An integrated nanogold/expanded graphite based sensor was fabricated by a former electrochemical etching of the pencil lead electrode (PLE) and a later in-situ deposition of gold nanoparticles (AuNPs). The electrochemical pretreatment of PLE (EPLE) created a 3D graphene-like surface, enhanced the electrode surface area and facilitated the electron...
