Next Generation Hosts for Protein Recognition, Assembly and More

Chemistry – A European Journal, Volume 32, Issue 30, 13 August 2026.
The original design of synthetic receptors for proteins was based on macrocycles with a hydrophobic core and a polar/charged periphery. This design, geared towards protein recognition, facilitates receptor self‐assembly. Macrocycle oligomerization, in turn, contributes to protein assembly as evidenced in many cocrystal structures.

‐Porphyrin/Perylene‐bisimide Array

, 2019
A side-to-face array DPy-gPBI[Ru(4-tBuTPP)(CO)]2, based on a “green” perylene bisimide chromophore sandwiched between two RuII-porphyrins, has been prepared by self-assembly. Its photophysical properties have been characterized in detail by a combination

Synthesis of DNA Building Blocks With Aminonaphthalimides and Cyanovinylenes as Uncharged Fluorophores: Fluorescent Readout From Turn‐On to Red‐Shift

European Journal of Organic Chemistry, Volume 29, Issue 29, 7 August 2026.
DNA architectures with aminonaphthalimides and cyanovinylenes as base surrogates form interstrand and intrastrand dimers showed that can be used as nucleic acid‐sensitive probes by their fluorescence turn‐on and red‐shift as readouts. The fluorescence turn‐on was tested by probing N6‐methyl‐2’‐deoxyadenosine (m6A) in DNA.

Perylene-3,4:9,10-tetracarboxylic Acid Bisimide Dye as an Artificial DNA Base Surrogate

, 2006
A phosphoramidite of the perylene bisimide dye was synthesized as a DNA building block that allows incorporation of this chromophore as an artificial nucleoside surrogate either at the 5'-terminus or at internal positions of duplex DNA.

On the Planarity of Heterocyclic Bay‐Substituted Perylenediimides: Insight into the Fluorescent Photoinduced Electron Transfer Sensing Framework

European Journal of Organic Chemistry, Volume 29, Issue 26, 13 July 2026.
Near‐infrared fluorescent pH indicators based on perylenediimide were constructed in a modular receptor–spacer–fluorophore–spacer–receptor format with heterocyclic amino moieties at the bay positions. Counterintuitively, the dibrominated intermediate with two heavy atoms is more emissive than the heterocyclic compounds.

Mutual Interplay of Light Harvesting and Triplet Sensitizing in a Perylene Bisimide Antenna−Fullerene Dyad

, 2016
A flexible organic dyad consisting of a perylene bisimide antenna covalently linked to a [60]fullerene has been synthesized and studied by electrochemistry, steady-state spectroscopy, and time-resolved spectroscopy.

Facile Synthesis of Dicyclohepta[cd,fg]‐as‐indacene and Confirmation of its Anti‐Kasha S3 Emission

ChemistryEurope, Volume 4, Issue 6, June 2026.
A six‐step synthesis of dicyclohepta[cd,fg]‐as‐indacene bearing phenyl and methyl groups was developed, which was achieved by a new strategy to prepare a 4,4’‐biazulene scaffold via single‐electron reduction‐induced dimerization of 6‐methylazulene. During the detailed investigation of the photophysics of dicyclohepta[cd,fg]‐as‐indacene, anti‐Kasha ...

Basics and Perspectives of Visible and Near‐UV Light‐Induced Defluorination of Perfluoroalkylsubstances by Semiconductor Nanocrystals

ChemPhotoChem, Volume 10, Issue 6, June 2026.
This review highlights recent advances in the light‐driven destruction of persistent per‐ and polyfluoroalkyl substances (PFASs) using semiconductor nanocrystals. By exploiting nonlinear photophysical and photochemical processes, these nanomaterials harness energy‐efficient visible and near‐UV light‐emitting diodes (LEDs) to drive extreme reduction ...

Long Versus Short Chain Covalent Functionalization in the Preparation of Mechanochromic Polymers

Chemistry–Methods, Volume 6, Issue 5, May 2026.
A perylene bisimide (PBI) macromechanophore featuring poly(ε‐caprolactone) (PCL) spacers was covalently incorporated into poly(styrene‐ethylene‐butylene‐styrene) (SEBS) and low‐density polyethylene (LLDPE) matrices. Compared to a short‐spacer PBI, the long‐spacer enhanced force transduction while preserving mechanical properties.

Visualization of various supramolecular assemblies of oligo(para- phenylenevinylene)-melamine and perylene bisimide

, 2008
A melamine derivative has been covalently equipped with two oligo(para-phenylenevinylene) (OPV) chromophores. This procedure yields a bifunctional molecule with two hydrogen-bonding arrays available for complementary binding to perylene bisimide ...
