T½ Tuning in a Synergistic BODIPY‐Tetrazole Fe(II) Spin‐Crossover‐Photoluminescence System via Co‐Ligand Variation

Chemistry – A European Journal, EarlyView.
We report a modular spin crossover‐photoluminescence (SCO‐PL) system: heteroleptic, mononuclear Fe(II) coordination compounds bearing equatorial BODIPY fluorophores that exhibit synergistic PL response upon spin state switching. Exchanging apical nitrile co‐ligands tunes electronic and structural properties, giving precise control over the SCO and PL ...

OPTICAL BISTABILITY IN A GAAS/GAALAS MULTI-QUANTUM-WELL (MQW) SELF-ELECTROOPTIC EFFECT DEVICE (SEED)

, 1991
Based on a GaAs/GaAlAs MQW pin structure grown by a home-made MBE system, we have successfully fabricated a SEED. The optical bistability and related properties of the device under symmetric operation (S-SEED) and asymmetric operation are ...

Static bistability of spherical caps

, 2018
Depending on its geometry, a spherical shell may exist in one of two stable states without the application of any external force: there are two ‘self-equilibrated’ states, one natural and the other inside out (or ‘everted’).

A High Energy Barrier DyIII2 Single‐Molecule Magnet Supported by a Bulky, Anionic N–O Bridging Ligand

Chemistry – A European Journal, EarlyView.
Complex [Dy2(hynad)2(dbm)4] was prepared by the employment of the anionic N–O‐based bridging and chelating N‐hydroxy‐1,8‐naphthalimide ligand, featuring a {Dy2(µ‐OR)2}4+ core and exhibiting zero‐field SMM behavior with a Ueff value of 171 K and double‐S‐shaped hysteresis loops, open up to 3.5 K.

Polarization bistability of vertical-cavity surface-emitting lasers under Larmor precession of electron spins

APL Photonics
Polarization bistability of vertical-cavity surface-emitting lasers (VCSELs) is the situation in which two orthogonal linear polarization states can selectively and stably exist for a single operation condition (e.g., injected current and temperature ...

Enhanced Optical Bistability of a Metasurface Based on Asymmetrically Optimized Mirror-Induced Magnetic Anapole States

Applied Sciences
In the field of modern optical computing and communication, optical bistability plays a crucial role. With a weak third-order nonlinear coefficient, low switch thresholds of optical bistability from Si-based nanophotonic structures remain a challenge. In

Investigation of critical slowing down in a bistable S-SEED

, 2003
A simulation of S-SEED switching based upon experimental data is developed that includes the effect of critical slowing down. The simulation's accuracy is demonstrated by close agreement with the results from experimental S-SEED switching. The simulation

Hydroquinone Oxidation by Redox‐active Guanidines and Thioguanidines: Faster Conversion to High‐Potential Than to Low‐Potential Quinones

Chemistry – A European Journal, EarlyView.
New redox‐active oligothioguanidines are developed and used in dehydrogenative P–P coupling reactions and hydroquinone oxidations. Tetrathioguanidino‐ and tetraguanidinobenzenes oxidize high‐potential halogenated hydroquinones faster than relatively low‐potential hydroquinone.
