Charge Transfer Through Dithieno[2,3-a:3',2'-c]phenazine: Effect of Substitution Pattern on the Optoelectronic Properties of Regioisomeric Luminophores.

Chemistry, an Asian journal

Chen Y, Lu X, Xiang C, Ling Y, Zhou G.
PMID: 26790136
Chem Asian J. 2016 Mar 18;11(6):874-81. doi: 10.1002/asia.201501389. Epub 2016 Feb 02.

Two series of regioisomeric luminophores that contained a dithieno[2,3-a:3',2'-c]phenazine (DTP) unit as an electron acceptor have been designed and synthesized. To investigate the effect of substitution pattern on the optoelectronic properties of these luminophores, electron donors (N,N-dihexylaniline or N,N-dihexyl-4-vinylaniline)...

PMID: 28364116
Nat Commun. 2017 Mar 31;8(1):8. doi: 10.1038/s41467-017-00021-9.

Ultrastable high-spectral-purity lasers have served as the cornerstone behind optical atomic clocks, quantum measurements, precision optical microwave generation, high-resolution optical spectroscopy, and sensing. Hertz-level lasers stabilized to high-finesse Fabry-Pérot cavities are typically used for these studies, which are large...

Rapid Virtual Stenting for Intracranial Aneurysms.

Proceedings of SPIE--the International Society for Optical Engineering

Proc SPIE Int Soc Opt Eng. 2016 Feb 27;9786. doi: 10.1117/12.2216123. Epub 2016 Mar 18.

The rupture of Intracranial Aneurysms is the most severe form of stroke with high rates of mortality and disability. One of its primary treatments is to use stent or Flow Diverter to divert the blood flow away from the...

HMGB1 exacerbates bronchiolitis obliterans syndrome via RAGE/NF-κB/HPSE signaling to enhance latent TGF-β release from ECM.

Am J Transl Res. 2016 May 15;8(5):1971-84. eCollection 2016.

Bronchiolitis obliterans syndrome (BOS), characterized by progressive airflow obstruction, is the main barrier to long-term graft survival after lung transplantation. Despite extensive studies, the mechanisms underlying BOS remain poorly understood, and targeted interventions have not yet been fully developed....

Structure and Composition of the 200 K-Superconducting Phase of H2 S at Ultrahigh Pressure: The Perovskite (SH(-) )(H3 S(+) ).

Angewandte Chemie (International ed. in English)

Angew Chem Int Ed Engl. 2016 Mar 07;55(11):3682-4. doi: 10.1002/anie.201511347. Epub 2016 Feb 08.

At ultrahigh pressure (>110 GPa), H2 S is converted into a metallic phase that becomes superconducting with a record Tc of approximately 200 K. It has been proposed that the superconducting phase is body-centered cubic H3 S (Im3‾ m,...

Low threshold optical bistability at terahertz frequencies with graphene surface plasmons.

Scientific reports
