Development of Aromaticity‐Tunable Meso‐Edited Phthalocyanine Derivatives

ChemistryEurope, Volume 4, Issue 4, April 2026.
Phthalocyanines show remarkable visible‐near‐infrared (NIR) photophysical properties, but their structural diversity is limited. This work reports the synthesis of various meso‐edited phthalocyanine‐metal complexes via deprotonative macrocyclization. These macrocycles exhibit 16π‐antiaromaticity, 17π‐radical character, and 18π‐aromaticity depending on ...

Acid/Base‐Triggered (Chir)Optical Switching and Efficient Singlet Oxygen Generation from a Pyrene‐Extended Azahelicene

ChemistryEurope, Volume 4, Issue 4, April 2026.
A pyrene‐extended azahelicene delivers proton‐switchable NIR absorption, fluorescence quenching, and reversible chiroptical responses (circular dichroism (CD)/circularly polarized luminescence (CPL)), together with efficient singlet oxygen generation (SOG), making it a promising proton‐responsive photofunctional system.

Ultralong Phosphorescence From a Simple Push–Pull Naphthalonitrile

ChemPhotoChem, Volume 10, Issue 4, April 2026.
A donor‐acceptor naphthalonitrile (NMe2) showsthermally activated delayed fluorescence and ultra‐long phosphorescence without heavy atoms. Strong charge‐transfer character and a small singlet‐triplet gap enable efficient ISC and RISC. Rigid matrices and 3D‐printed polymers stabilize triplet states, producing temperature‐dependent long‐lived afterglow ...

Incorporating Pentaphenyl Group Into Anthracene Core for Highly Efficient Nondoped Deep‐Blue Organic Light‐Emitting Diode Emitters With CIE y = 0.06

ChemPhotoChem, Volume 10, Issue 4, April 2026.
Novel anthracene‐based deep‐blue emitters are developed for non‐doped organic light‐emitting diodes (OLEDs) utilizing the triplet‐triplet annihilation (TTA) mechanism. These materials achieve a high external quantum efficiency (EQE) of 7.66% and excellent color purity with CIE coordinates of (0.15, 0.06), demonstrating an effective strategy for high ...

Excimer Formation in Aqueous Solutions of Hosts and Application in Synthesis

ChemPhotoChem, Volume 10, Issue 4, April 2026.
This review explores how host‐mediated excimer formation in water, facilitated by supramolecular confinement enhances photochemical synthesis. By improving solubility, local concentrations, and orientational control, these systems can boost efficiency and selectivity in reactions like photocycloadditions and photodimerizations.
