Red‐emissive π‐expanded diketopyrrolopyrroles (DPPs) with fluorescence reaching λ=750 nm can be easily synthesized by a three‐step strategy involving the preparation of diketopyrrolopyrrole followed by N‐arylation and subsequent intramolecu

Biomimetic and bioinspired molecular electrets. How to make them and why does the established peptide chemistry not always work?

Autor: Jillian M. Clinton, Eli M. Espinoza, James B. Derr, Bing Xia, Valentine I. Vullev, Maryann Morales, Kamil Skonieczny

“Biomimetic” and “bioinspired” define different aspects of the impacts that biology exerts on science and engineering. Biomimicking improves the understanding of how living systems work, and builds tools for bioinspired endeavors. Biological

Suppressing the charge recombination (CR) that follows an efficient charge separation (CS) is of key importance for energy, electronics, and photonics applications. We focus on the role of dynamic gating for impeding CR in a molecular rotor, comprisi

Lauft die durch AlCl3 bei hoher Temperatur und auch durch FeCl3, MoCl5, PIFA oder K3[Fe(CN)6] bei Raumtemperatur vermittelte, dehydrierende Kupplung aromatischer Verbindungen in allen Fallen nach dem gleichen Mechanismus ab? Durch die wachsende Bedeu

Photochemical Conversion of Phenanthro[9,10-d]imidazoles into π-Expanded Heterocycles

Autor: Daniel T. Gryko, Kamil Skonieczny

Publikováno v: The Journal of organic chemistry. 80(11)

We discovered that phenanthro[9,10-d]imidazoles bearing a 2-halogenoaryl substituent at position 2 undergo swift photochemically driven direct arylation, leading to barely known phenanthro[9',10':4,5]imidazo[1,2-f]phenanthridines. The reaction is hig
