Temperature‐Dependent Optical Properties of CsCu2I3 Perovskites

open access: yesAdvanced Materials Interfaces, EarlyView.
This work explores the temperature‐dependent optical properties of CsCu₂I₃ nanocrystals using transmittance and photoluminescence techniques. Resonant excitation conditions and energy level modeling reveal critical insights into the self‐trapped exciton emission mechanism.

Chemo- and Regioselectivity in the Reaction of Tetrachloro- and Tetrabromophthalic Anhydrides and Imides with Thiolates

open access: yesCHIMIA, 1991
The reaction of tetrachloro- and tetrabromophthalic anhydrides and -imides with in situ generated aryl and alkyl thiolates gives mono- to tetrathio-substituted derivatives depending on reagent, stoichiometry, and reaction conditions.

Electrochemical Modulation of Hole Extraction in NiO/Perovskite Bilayers

open access: yesAdvanced Materials Interfaces, EarlyView.
The influence of hole depletion/accumulation on the hole extraction is evaluated in NiO/perovskite bilayers by transient spectroelectrochemical measurements. Metal‐halide perovskite thin films with different valence band positions are prepared, and the influence of band offset on the hole extraction kinetics is studied.

Organic–Inorganic Hybrid Indium Halide Perovskites with Near‐Unity Photoluminescence Quantum Yield

open access: yesAdvanced Materials Interfaces, EarlyView.
The intrinsic low photoluminescence quantum yield (PLQY) of organic–inorganic hybrid halide perovskites has limited their applications in optoelectronic devices. In this work, novel (PMA)₄InCl₇·0.5H₂O single crystals are developed and a PLQY of approximately 100% through optimized antimony ion (Sb3⁺) doping is achieved. The light‐emitting diodes (LEDs)

Antifouling PEG Coatings by Thiol‐Acrylate Conjugate Addition Reactions for Generation of Protein Patterns via Photobleaching‐Induced Protein Binding (PiPB) BioBitmaps Using Maskless Projection Lithography

open access: yesAdvanced Materials Interfaces, EarlyView.
Homo‐bifunctional PEG, acrylate‐PEG‐acrylate (PEGDA), coatings are prepared on glass and glass‐type surfaces using solvent‐free thiol‐acrylate conjugate addition reactions at room temperature. The prepared PEGDA coatings are stable, antifouling, and provide feature terminal acrylates that can act as free radical acceptors for photobleaching‐induced ...
