Dipole‐Manipulated Built‐In Electric Field Enables Ultrafast Charge Separation in Perylene Diimide Polymers for Photoelectrochemical Water Splitting

Advanced Science, Volume 13, Issue 43, 3 August 2026.
Molecular dipole engineering in dendritic perylene diimide polymers through nitrogen‐rich heterocyclic linkers amplifies the built‐in electric field, enabling sub‐picosecond charge separation and efficient multi‐electron accumulation. This structure–dynamics–performance relationship establishes a versatile design strategy for high‐performance organic ...

Aromaticity‐Engineered Open‐Shell Radical Anions for Air‐Stable Doublet Emission in N‐Annulated Perylene Diimide

Advanced Science, Volume 13, Issue 47, 24 August 2026.
Open‐shell type radical anions with stable doublet emission have been synthesized that feature aromaticity engineering, through‐space charge‐transfer (TSCT), and electro(fluoro)chromism. ABSTRACT We report the doublet emissive open‐shell radical anions, where the N‐annulated perylene diimide (PDIN–H) is functionalized with aromatic rings.

N‐Annulated Perylene Diimide Emitters for High‐Performance Peroxyoxalate/H2O2 Chemiluminescence

Luminescence, Volume 41, Issue 8, August 2026.
Spooling chemiluminescence (CL) spectroscopy has been utilized to investigate two N‐annulated perylene diimide (PDI) dimers with hexyl linear alkyl chains (PDI‐1) and 2,4,6‐trimethylbenzyl sidechains (PDI‐2) at the pyrrolic N‐positions, on their CL reaction mechanism, illuminant decay and absolute CL efficiencies.

Modified Single Amino Acid‐Based Semiconductor: A Minimalistic Approach

ChemNanoMat, Volume 12, Issue 8, August 2026.
This study introduces a minimalistic strategy for generating semiconducting biomaterials from modified single amino acids. Eight molecules were synthesized and structurally verified using mass spectrometry, NMR, SC‐XRD, and PXRD. BNI‐L‐Phe, BNI‐L‐Tyr, and BNI‐n‐Hex crystallized in a monoclinic system, while BNI‐D‐Leu formed an orthorhombic structure ...
