Halogenated Tryptophans Improve Integrin αVβ6 Affinity of Cyclic RGD Peptides and Provide Handles for Late‐Stage Derivatization

Chemistry – A European Journal, EarlyView.
Lighting up αVβ6: Halotryptophan engineering converts an RGD scaffold into a modular αVβ6 ligand platform, enabling picomolar affinity and late‐stage functionalization. The resulting probes combine high selectivity with fluorescence for FACS and tumor imaging.

Infrared Irradiation‐Assisted Pd‐Catalyzed C(sp3)─H Arylation and Tandem Cyclization of Ortho‐Tolualdehydes

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.

Towards Halogen Bonding MOFs: Networking With a Polyiodinated and Perfluorinated Terphenyl Ligand and Divalent Zinc

Chemistry – A European Journal, EarlyView.
One ligand, three new architectures with different intermolecular interactions: a polyhalogenated terphenyl linker with carboxyl groups coordinates Zn2+ to form (i) a metal‐containing hydrogen‐bonded organic framework; (ii) a metal‐organic framework or (iii) one‐dimensional metal‐organic chains with intermolecular halogen bonding and hydrogen bonding ...

Synthesis and Photophysical Properties of Star‐Shaped Triphenylamine Trimers Functionalized With BODIPY and Subphthalocyanine Chromophores

Chemistry – A European Journal, EarlyView.
This study investigates how molecular topology influences the photophysical properties of star‐shaped, threefold‐symmetric triphenylamine (TPA) derivatives functionalized with three BODIPY or SubPc units. Their absorption spectra exhibit minimal solvatochromism, whereas their fluorescence intensity is strongly dependent on solvent polarity.

Xanthene‐Based FLPs Featuring Perchloroarylborane Substitutents: Interplay of Noncovalent Aggregation and Dihydrogen Activation

Chemistry – A European Journal, EarlyView.
Frustrated Lewis Pairs featuring perchloroarylborane Lewis acid groups are found to display unprecedented H2 uptake as a function of temperature, resulting from the thermodynamic balance between H─H cleavage and noncovalent intermolecular aggregation.

Photostability of Cyanine Dyes and Its Correlation to Their Photothermal and Photodynamic Effects

Chemistry – A European Journal, EarlyView.
Photostability (PS) of dyes is a crucial parameter for performance in biological applications, yet often underrated. Here PS of several cyanines is investigated. The method is carefully evaluated and designed as a general and easy tool to compare PS of NIR dyes.

Encapsulation of Linear and Cyclic Alkanes in Water Within a Dimeric Deep‐Cavity Sulfonatocalix[4]arene Capsule

Chemistry – A European Journal, EarlyView.
Captured in water. A tetrasulfonated deep‐cavity calix[4]arene encapsulates linear and cyclic alkanes, as well as benzene and hexafluorobenzene, in water by forming a self‐assembled dimeric capsule. The binding affinity is guest size‐dependent. For linear alkanes, the affinity peaks at n‐hexane, while cyclooctane is the most strongly bound cycloalkane.

Designing Threefold π‐Surfaces Through Peripheral Halogenation to Shape Multidirectional Molecular Packing

Chemistry – A European Journal, EarlyView.
The complete series of hexahalogenated triptycene‐tribenzoquinones, comprising newly synthesized fluoro‐, bromo‐, and iodo‐substituted derivatives together with the previously reported chloro analogue, enables systematic comparison of their molecular properties and intermolecular interactions in relation to their crystal packing modes.
