Hybridized Charge‐Transfer Window within a Fully Conjugated Multi‐Resonance Thermally Activated Delayed Fluorescence Framework for Ultrafast Reverse Intersystem Crossing and High‐Efficiency in Deep‐Blue Organic Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
A hybridized charge‐transfer window combining short‐range and long‐range charge transfer is realized within a fully conjugated multi‐resonance thermally activated delayed fluorescence framework. The resulting excited‐state hybridization minimizes the singlet–triplet energy gap (0.04 eV) and enables ultrafast reverse intersystem crossing (krISC = 2.1 ...

Control of asymmetric biaryl conformations with terpenol moieties: Syntheses, structures and energetics of new enantiopure C2-symmetric diols

open access: yesBeilstein Journal of Organic Chemistry, 2008
New enantiopure, C2-symmetric biphenyl-2,2′-diols based on (−)-menthone (BIMOL), (−)-verbenone (BIVOL) and (−)-carvone (BICOL and hydrogenated BIMEOL), are accessible via short, synthetic routes. All diols form intramolecular hydrogen bonds and hence can

Bioconversion of biphenyl to a polyhydroxyalkanoate copolymer by Alcaligenes denitrificans A41

open access: yesAMB Express, 2020
A polyhydroxyalkanoate (PHA) copolymer, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HB-co-3HV)], was biosynthesized from biphenyl as the sole carbon source using Alcaligenes (currently Achromobacter) denitrificans A41.

Bay‐functionalized [7]Helicene Bilayer Nanographenes

open access: yesAdvanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

Designing organometallic compounds for catalysis and therapy [PDF]

open access: yes, 2012
Bioorganometallic chemistry is a rapidly developing area of research. In recent years organometallic compounds have provided a rich platform for the design of effective catalysts, e.g. for olefin metathesis and transfer hydrogenation.

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

open access: yesAdvanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

An Organometallic [2]Catenane With Pt‒(di‐NHC)‒Pt Units: A Topology‐Driven Strategy for Enhanced Phosphorescence in Discrete Aggregates

open access: yesAngewandte Chemie, EarlyView.
The mechanically interlocked Borromean rings are stabilized by π···π stacking interactions while the [2]catenane is stabilized by solvophobic effects. While the π···π interactions in the Borromean rings lead to severe luminescence quenching, the solvophobically assembled [2]catenane effectively circumvents these interactions, simultaneously restricting

Ideal gas thermodynamic properties for the phenyl, phenoxy, and o-biphenyl radicals [PDF]

open access: yes
Ideal gas thermodynamic properties of the phenyl and o-biphenyl radicals, their deuterated analogs and the phenoxy radical were calculated to 5000 K using estimated vibrational frequencies and structures. The ideal gas thermodynamic properties of benzene,
