Using Genetic Algorithms to Discover Novel Ground- State Triplet Conjugated Polymers

open access: yes, 2022
Stable ground-state triplet π-conjugated copolymers have many interesting electronic and optoelectronic properties. However, the large number of potential monomer combinations makes it impractical to synthesize or even just use density functional theory (

The T1 state of p-nitroaniline and related molecules: a CNDO/S study

open access: yes, 1983
The nature of the lowest energy triplet state (T1) of p-nitroaniline (PNA), N,N-dimethyl-p-nitroaniline (DMPNA) and nitrobenzene (NB) is reexamd. using the semiempirical CNDO/S-CI method with selected parameter options.

Dynamics of unfolded and [alpha]-helical polypeptide chains [PDF]

open access: yes, 2007
The aim of this thesis was the investigation of the dynamics of elementary steps in protein folding. During folding, the polypeptide chain explores the free energy surface and first interactions are established. These interactions lead to formation of

N,N′-Diaryldihydrophenazines as a Sustainable and Cost-Effective Alternative to Precious Metal Complexes in the Photoredox-Catalyzed Alkylation of Aryl Alkyl Ketones

open access: yesMolecules, 2022
An inexpensive and highly efficient metal-free alternative to commonly used Ru- and Ir-based catalysts was proposed. It was shown that the new 2,7-di-tert-butyl-5,10-bis(4-trifluoromethylphenyl)-5,10-dihydrophenazine outcompeted the iridium phenylpyridyl

Validation of the triplet ground state in a persistent derivative of Clar’s hydrocarbon

open access: yes, 2021
Triangulene is a prototypical non-Kekulé diradical known as Clar’s hydrocarbon. It is the smallest non-Kekulé graphene fragment comprised of six benzenoid rings fused in a triangular shape.

Triplet-Fusion Upconversion Using a Rigid Tetracene Homodimer

open access: yes, 2019
We demonstrate that a structurally rigid, weakly coupled molecular dimer can replace traditional monomeric annihilators for triplet fusion upconversion (TUC) in solution by observing emitted photons (λ = 540 nm) from a norbornyl-bridged tetracene ...

Singlet and triplet excited-state dynamics of a nonfullerene electron acceptor Y6

open access: yes, 2021
Understanding the excited-state dynamics of nonfullerene electron acceptors is essential for further improvement of organic solar cells. Herein, we investigated the singlet and triplet excited-state dynamics in Y6, a novel nonfullerene acceptor, using ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

open access: yesFEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,
