Orchestrating Anion-π⁺ Interactions to Accelerate Metal-Free Room-Temperature Phosphorescence. [PDF]

Angew Chem Int Ed Engl
Tuning anion–π+ interactions in pyridinium iodide contact ion pairs enables ultrafast metal‐free room‐temperature phosphorescence (540–605 nm) with radiative rates up to 5.2×105 s−1. Strong iodide→π+ charge‐transfer coupling, enhanced spin–orbit interactions, and dynamic ion‐pair organization accelerate intersystem crossing and emission, establishing ...

Click‐Spaltung quartärer Anilinium‐Tetrazine ermöglicht Kaskadenaufbau multifunktioneller biomolekularer Gerüste

Angewandte Chemie, EarlyView.
Die Click‐Chemie hat sich von dem Aufbau kovalenter Bindungen hin zum Spalten von Bindungen weiterentwickelt. Hier wird über einen Kaskaden‐Aufbau berichtet, der diese Verfahren kombiniert, um multifunktionale biomolekulare Gerüste in einer modularen Ein‐Topf‐Reaktion aufzubauen.

New Constituents from the Korean Sponge Plakortis simplex

Marine Drugs, 2013
Six new cyclic peroxides (1–6) were isolated from the Korean sponge Plakortis simplex, along with two new alkylpyridinium alkaloids (7 and 8). The structures of these compounds were completely determined by a combination of NMR analysis and chemical ...
