Dual Chemical Looping/Catalytic Process for Alkylation of Benzene With Ethane and Propane Yielding Ethylbenzene and Cumene Over Copper‐Containing Mordenite

Angewandte Chemie, EarlyView.
We report a dual chemical looping/catalytic process coupling alkane dehydrogenation with aromatic alkylation over Cu‐mordenite, yielding up to 25% alkylated aromatics with >95% selectivity per cycle. In situ NMR, FTIR spectroscopy, and DFT show alkylation proceeds via a π‐bound Cu(I)–olefin intermediate and Brønsted acid sites.

Tetraaza[7]–[15]helicenes Synthesized by Two‐Step Strategy: Length‐Controlled Chiral π‐Systems Exhibiting Amplified Circularly Polarized Luminescence

Angewandte Chemie, EarlyView.
A modular two‐step strategy provides tetraaza[n]helicenes (n = 7–15) as a homologous series with tunable photophysical and chiroptical properties. Extension beyond n = 11 induces pronounced through‐space π–π interactions, narrowing the energy gap and amplifying circularly polarized luminescence.

Low-temperature formation of polycyclic aromatic hydrocarbons in Titan’s atmosphere [PDF]

, 2018
The detection of benzene in Titan’s atmosphere led to the emergence of polycyclic aromatic hydrocarbons (PAHs) as potential nucleation agents triggering the growth of Titan’s orange-brownish haze layers. However, the fundamental mechanisms leading to the

Orientation-dependent ionization yields from strong-field ionization of fixed-in-space linear and asymmetric top molecules

, 2011
The yield of strong-field ionization, by a linearly polarized probe pulse, is studied experimentally and theoretically, as a function of the relative orientation between the laser field and the molecule. Experimentally, carbonyl sulfide, benzonitrile and

Host‐Guest Doping Enables Room Temperature Phosphorescence from Triarylboranes

Angewandte Chemie, EarlyView.
While pure triarylboranes show RTP in annealed PMMA films, they do not in crystalline form, contrary to our previous report. However, crystalline host‐guest triarylborane systems show persistent afterglow up to 8 s even at 1 ppb guest loading. Computations identify triplet‐triplet energy transfer as the mechanism governing this efficient RTP.
