Photoelectrochemical overall water splitting has been considered as a promising approach for producing chemical energy from solar energy. Although many photoelectrochemical cells have developed by coupling two semiconductor photoelectrodes, inefficient charge transfer between the light-harvesters and electron acceptor/donor severely restricts conversion efficiency. Inspired natural photosynthesis, we assembled platform with multimediator modulation to achieve unassisted splitting....
Abstract Two molecules, 1-hydroxypyrene-2-carbaldehyde (HP) and 1-methoxypyrene-2-carbaldehyde (MP) were explored. We investigated their photophysical properties, using experimental transient absorption theoretical density functional theory/time-dependent theory (DFT/TDDFT). HP MP have similar geometric conformations but exhibit entirely different properties upon excitation into the S 1 state. In contrast to traditional excited state intramolecular proton transfer (ESIPT) in molecules that...
3-HTF easiest to carry out ESIPT reaction would exhibit the highest efficient antioxidant activity among three compounds.
Acceleration of ultrafast processes is vital in hydrogen-bonded coumarin–methanol complexes for improving the photoelectric conversion efficiency dye-sensitized solar cells (DSSCs). The traditional methods expedite individually related to electron injection DSSCs, namely, internal (IC) or intermolecular charge transfer (inter-CT), by adjusting molecular topologies. We introduce pressure as an external drive realize acceleration both simultaneously without changing configuration. In definite...
The multiple proton transfer reactions of 3-hydroxypyridine-(H<sub>2</sub>O)<sub>3</sub>have been demonstrated, and a perfect cycle has revealed in the ground excited states.
Photonic crystals incorporating with plasmonic nanoparticles have recently attracted considerable attention due to their novel optical properties and potential applications in future subwavelength optics, biosensing data storage device. Here we demonstrate a free-standing chiral film composed of entropy-driven self-co-assembly gold (GNPs) rod-like cellulose nanocrystals (CNCs). The CNCs–GNPs composite films not only preserve the photonic ordering CNCs matrix but also retain resonance GNPs,...
The effect of hydrogen bonding on the intermolecular photoinduced ICT and TICT processes for coumarin 500 has been demonstrated, a reliable mechanism revealed to explain unusual behavior C500 in dioxane methanol.
Constructing two-dimensional (2D) van der Waals (vdW) heterostructures is becoming a promising way for photocatalytic water splitting to produce hydrogen. In this Letter, we perform 2D vdW blue phosphorous/β-AsP (BP/β-AsP) heterostructure based on density functional theory calculations. The type II band alignment in the BP/β-AsP beneficial separating photogenerated electrons and holes suppressing their recombination. not only keeps suitable edge position reaction but also significantly...

The excited-state double proton transfer (ESDPT) process of dipyrido[2,3-a:3',2'-i]carbazole (DPC) in ethanol (EtOH) solvent is investigated using density functional theory (DFT) and time-dependent (TDDFT). computational results provide convincing evidence that did not occur spontaneously for the DPC monomer due to lack hydrogen bonds. Interestingly, after adding EtOH DPC, two intermolecular bonds were formed ground-state, strengthened excited-state, as confirmed by comparing changes primary...
Harnessing ingenious modification of molecular structure to regulate excited-state intramolecular proton transfer (ESIPT) and charge (ICT) characteristics holds great promise in fluorescence sensing imaging. Based on the 3-hydroxyflavone (3HF) molecule, 2-(2-benzo[b]furanyl)-3-hydroxychromone (3HB) 2-(6-diethylamino-benzo[b]furan-2-yl)-3-hydroxychromone (3HBN) were designed by extension furan heterocycle introduction a diethylamino group. The analysis important hydrogen bond length, frontier...
