Probing the Wave Function and Dynamics of the Quintet Multiexciton State with Coherent Control in a Singlet Fission Material

Physical Review X, 2020
High-spin states play a key role in chemical reactions found in nature. In artificial molecular systems, singlet fission produces a correlated triplet-pair state, a spin-bearing excited state that can be harnessed for more efficient solar-energy ...

Triplet Rydberg States of Aluminum Monofluoride

The Journal of Physical Chemistry A
Aluminum monofluoride (AlF) is a suitable molecule for laser cooling and trapping. Such experiments require an extensive spectroscopic characterization of the electronic structure. Two of the theoretically predicted higher lying triplet states of AlF, the counterparts of the well-characterized D$^1Δ$ and E$^1Π$ states, had experimentally not been ...

A DFT Study of the Photochemical Dimerization of Methyl 3-(2-Furyl)acrylate and Allyl Urocanate

Molecules, 2014
A DFT study of the photochemical dimerization of methyl 3-(2-furyl)acrylate is reported. The photochemical reaction gave a mixture of two dimers with high regioselectivity and good stereoselectivity.

Highly sensitive X-ray responsive molecular switches

Nature Communications
X-ray-triggered molecular switching promises remote control behind physical barriers, yet existing radioswitches typically require multi-gray doses to reach a photostationary state.

Organic phosphorescence in Pt(II)-complexes linked to organic chromophores for blue-emitting organic light-emitting diodes

Communications Chemistry
Recently, organic persistent room-temperature phosphorescence (OPRTP), entailing triplet-state emission from purely organic units instead of luminescent heavy metal complexes, has emerged as a promising alternative for the development of emitting ...

Small Singlet–Triplet Gap Terpolymer Donor with a Simple Pt Complex Enables Organic Solar Cells with Low Energy Loss and Over 19.2% Efficiency

Advanced Science
Suppressing the non‐radiative loss in the organic solar cells (OSCs) through molecular design remains a significant challenge. Typically, triplet state of organic semiconductors is lower than the charge transfer (CT) state, contributing to substantial ...

Chemiexcitation in preventing macular degeneration

Frontiers in Photonics
Quantum biology typically involves light exciting an electron to a higher energy state, or a magnetic field splitting a single state into several having different energies, or tunneling to flout the energy barrier between states.

Twisted Anthracene-Fused BODIPY: Intersystem Crossing and Torsion-Induced Non-Radiative Relaxation of the Singlet Excited State

Molecules
The photophysical properties of a BODIPY derivative with the highly twisted molecular structure of anthracene-fused boron–dipyrromethene (AN-BDP) were studied with steady-state and time-resolved spectroscopic methods.
