Large Inverted SingletTriplet Energy Gaps Are Not Always Favorable for Triplet Harvesting: Vibronic Coupling Drives the (Reverse) Intersystem Crossing in Heptazine Derivatives

, 2021
Heptazine derivatives are promising dopants for electroluminescent devices. Recent studies raised the question whether heptazines exhibit a small regular or an inverted singlet–triplet (IST) gap.

Insights Into Symmetry and Substitution Patterns Governing Singlet–Triplet Energy Gap in the Chemical Space of Azaphenalenes

Chemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
ABSTRACT Molecules that violate Hund's rule by exhibiting an inverted singlet–triplet gap (STG), where the first excited singlet (S1${\rm S}_1$) lies below the triplet (T1${\rm T}_1$), are rare but hold great promise as efficient fifth‐generation light emitters.

Development of an Organic Emitter Exhibiting Reverse Intersystem Crossing Faster than Intersystem Crossing

Angewandte Chemie, Volume 136, Issue 35, August 26, 2024.
The inverted singlet‐triplet excited states (iST) molecule, A6AP‐Cz, based on asymmetric hexa‐azaphenalene was designed. A6AP‐Cz showed the extremely short lifetime of delayed fluorescence (τDF) of 54 ns. Moreover, the reverse intersystem crossing (rate constant of RISC: kRISC=1.9×107 s−1) was faster than ISC (rate constant of ISC: kISC=1.0×107 s−1 ...

Differentiating between F and OH Ligands in Homologous Gold(III) Complexes beyond X‐Ray Crystallography

European Journal of Inorganic Chemistry, Volume 28, Issue 34, December 1, 2025.
A subtle hydrogen‐bonding lock enables the unequivocal structural differentiation between fluoride and hydroxide in the unusual couple of homologous organogold(III) complexes [PPh4][(CF3)3AuF] and [PPh4][(CF3)3Au(OH)] (see adjacent figure). The homologous fluoride and hydroxide complexes of gold(III) [PPh4][(CF3)3AuX] [X = F (1), OH (2)] have been ...

Electromechanical Behavior of Axially Continuous Graphene–Copper Wires

Small Science, Volume 5, Issue 12, December 2025.
This study investigates the electromechanical behavior of 80 μm‐diameter axially continuous graphene–copper (ACGC80) wires by developing a customized tensile testing method. Experimental studies have shown that ACGC80 wires exhibit higher electrical conductivity compared to as‐received and annealed Cu wires, and more importantly, the Gr‐enhanced ...
