1,4,5,8-Naphthalenediimides (NDIs) are widely used motifs to design multichromophoric architectures due to their ease of functionalisation, their high oxidative power and the stability of their radical anion. The NDI building block can be incorporate

Lifetime Broadening and Impulsive Generation of Vibrational Coherence Triggered by Ultrafast Electron Transfer

Autor: Stefan Matile, Alexander Aster, Eric Vauthey, Anna-Bea Bornhof, Naomi Sakai

Publikováno v: Journal of Physical Chemistry Letters, Vol. 12 (2021) pp. 1052-1057

The absorption band shape of chromophores in liquid solution at room temperature is usually dominated by pure electronic dephasing dynamics, which occurs on the sub-100 fs time scale. Herein, we report on a series of dyads consisting of a naphthalene

Synergistic Anion–(π)n–π Catalysis on π-Stacked Foldamers

Publikováno v: Journal of the American Chemical Society, Vol. 140, No 14 (2018) pp. 4884-4892

In this report, we demonstrate that synergistic effects between π–π stacking and anion−π interactions in π-stacked foldamers provide access to unprecedented catalytic activity. To elaborate on anion–(π)n–π catalysis, we have designed, s

Publikováno v: Chemistry (Weinheim an Der Bergstrasse, Germany)

The de novo syntheses of chemically stable chlorins with five‐membered heterocyclic (furane, thiophene, formylfurane and formylthiophene) substituents in selected meso‐ and β‐positions are reported. Heterocycle incorporation in the 3‐ and 13

Induced π acidity from polarizability is currently emerging as most effective to stabilize anionic transition states on aromatic π surfaces, that is anion-π catalysis. To access extreme polarizability, we here propose a shift of attention from hom

The objective of this Account is to summarize the first five years of anion-π catalysis. The general idea of anion-π catalysis is to stabilize anionic transition states on aromatic surfaces. This is complementary to the stabilization of cationic tr

Rational Synthesis of 2-Bromoporphyrins and 2,12-Dibromoporphyrins

Autor: Anna-Bea Bornhof, Ruisheng Xiong, K. Eszter Borbas

Publikováno v: The Journal of organic chemistry. 82(23)

Bromoporphyrins were prepared by the metal-mediated self-condensation of brominated 1-formyldipyrromethanes. Depending on the conditions, Mg(II)-2,12-dibromoporphyrin and Mg(II)-2-bromoporphyrin could be obtained in up to 11% and 17% isolated yield,
