Red‐to‐Near‐Infrared Electroluminescence and Low‐Threshold Amplified Spontaneous Emission from Solution‐Processable Fluorescent Diketopyrrolopyrrole Derivatives

open access: yesChemPhotoChem, EarlyView.
The photophysical, electroluminescence, and amplified spontaneous emission properties of two solution‐processable fluorescent diketopyrrolopyrrole derivatives are examined in details. The results demonstrate that this type of organic near‐infrared light‐emitting materials are extremely promising for organic light‐emitting diodes and organic ...

Memristor‐Based Reconfigurable True Time Delay Circuit

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
A memristor‐controlled CMOS reconfigurable true time delay circuit is introduced in this paper. The memristor value variation changes the DC bias voltage inputs of the delay elements and thus controls the delay time indirectly. ABSTRACT A memristor‐controlled CMOS reconfigurable true time delay circuit is introduced in this paper.

AI‐Enhanced High‐Resolution Functional Imaging Reveals Trap States and Charge Carrier Recombination Pathways in Perovskite

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We use AI‐enhanced intensity modulation two‐photon excited fluorescence microscopy (ml‐IM2PM) to investigate defect properties and charge carrier recombination in MAPbBr3 films. Mapping exciton generation rate, trap concentration, and trap energy barriers and correlating spatially resolved charge carrier recombination pathways, we identify the ...

Synthesis, Characterization, and Electrochemical Properties of Tri‐ and Tetranuclear CoIII‐Oxo Complexes

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A series of three tetranuclear and two trinuclear Co(III) carboxylate complexes are synthesized and thoroughly spectroscopically and electrochemically characterized. The relative stability of the tetranuclear versus trinuclear complexes is investigated by density functional theory calculations, and the infrared and ultraviolet/visible spectra are ...
