Rh‐Catalyzed [2 + 2 + 2] Cycloaddition of Linked Bis(Diynes) Ar‐C≡C‐C≡C‐(CH2)3‐C≡C‐C≡C‐Ar With Quinones: Synthesis and Photophysical Properties of Bis(Arylethynyl)‐Naphthoquinones and Anthraquinones

Chemistry – A European Journal, EarlyView.
We report the synthesis bis(arylethynyl)naphtho‐ and anthraquinones via Rh(I)‐catalyzed [2 + 2 + 2] cycloaddition reactions. The substrate scope of both quinones and linked bis‐diynes was explored. Microwave irradiation remarkably enhanced yields.

Induced‐Fit Recognition by a Calixarene–Pyrene Conjugate for Single‐ and Dual‐Wavelength Fluorescence Sensing in Water

Chemistry – A European Journal, EarlyView.
A sulfonatocalix[4]arene–pyrene conjugate functions as a fluorescence chemosensor for the optical detection of biorelevant analytes in water. Its photoinduced electron transfer (PET) response is triggered by an induced‐fit recognition mechanism. Noncovalent assembly with an additional dye affords dual‐color ratiometric signaling via competitive PET ...

Chain Versus Ring: Characterization of a Meta‐Phenylene Ladder Polymer and Its Octameric Macrocycle

Chemistry – A European Journal, EarlyView.
The synthesis and comprehensive spectral and photophysical analysis of a methyl‐substituted ladder meta‐phenylene macrocycle (MeLMMP) and its polymer analogue (MeLPMP) show that, despite differing topologies (macrocycle vs. polymer), both display nearly identical electronic and photophysical properties due to cross‐conjugation.
