Chemistry – A European Journal, EarlyView.A rapid and efficient protocol for the synthesis of 2‐benzylbenzaldehydes and anthracenes is reported, based on the infrared (IR) irradiation‐assisted Pd‐catalyzed C(sp3)─H arylation and the tandem C(sp3)─H arylation/electrophilic aromatic cyclization of ortho‐tolualdehydes with aryl iodides via a transient directing group (TGD) strategy.

The synthesis of some substituted 7-(1-Naphthyl)- Benz(a)Anthracenes
, 2012 Many benz(a)anthracene derivatives are able to produce cancer in the experimental animal. There is a correlation between the calculated total electronic charge of the K-region and this carcinogenic activity.

Illuminating Olympicenes: Insights Into Anti‐Kasha Photophysics in Polycyclic Aromatic Hydrocarbons
Chemistry – A European Journal, EarlyView.Compact olympicene‐based chromophores reveal unexpectedly rich excited‐state behavior, including dual fluorescence, excitation‐dependent emission, and anti‐Kasha‐type emission. Tunable locally excited and intramolecular charge‐transfer states emerge from subtle structural changes, expanding the design rules for polycyclic aromatic chromophores and ...

European Journal of Organic Chemistry, EarlyView.Donor–acceptor and donor–donor systems incorporating an indeno[1,2‐b]fluorene‐extended tetrathiafulvalene (IF‐TTF) donor motif were prepared by Suzuki coupling reactions. The compounds were studied for their optical and redox properties. The compounds showed multiredox behavior with several accessible redox states. A series of π‐extended donor–acceptor

Fluorene‐based blue emitters: On the path to electrically pumped organic lasers
FlexMat, EarlyView.Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...
