Label‐Free Quantitative Analysis of Coacervates via 3D Phase Imaging

Coacervation has become an emerging mechanism for assembling biomolecular condensates inside and outside cells. However, collecting accurate values of quantitative parameters, especially concentration, are challenging owing to the dynamic nature of coacervates. A rapid, intact, label-free quantification of concentrations is demonstrated inside a coacervate...

Dendritic Interfacial Exciplex Hosts for Solution‐Processed TADF‐OLEDs with Power Efficiency Approaching 100 lm W−1

Two interfacial exciplex hosts formed between H2 donor and B4PyMPM (or B3PyMPM) acceptor are developed for solution-processed thermally activated delayed fluorescent organic light-emitting diodes. As a result of the enhanced carrier balance, the devices based on H2/B3PyMPM achieve a power efficiency (PE) of 95.0 lm W−1 (much better than that of H2/B4PyMPM...

Ultra‐Broadband Tunable Bragg–Berry Optical Vortex Generators of a Circularly Symmetric Chiroptic Structure

This study demonstrates Bragg–Berry optical vortex generators (BBOVGs) with a circularly-symmetric chiral photonic structure using ferroelectric liquid crystal-doped cholesteric liquid crystals (FLC-CLCs). The BBOVG devices can be operated to obtain reflective RGB optical vortices with opposite signs of topological charges by dynamically tuning the...

Enhanced Responsivity of CsCu2I3 Based UV Detector with CuI Buffer‐Layer Grown by Vacuum Thermal Evaporation

High quality CsCu2I3 thin films are fabricated by solvent-free vacuum thermal evaporation method. With the CuI buffer-layer, phase transformation and quality improvement of the perovskite thin film are obtained. With the CuI buffer-layer, the performance of UV photoconductive detectors based on CsCu2I3 film are enhanced. Abstract All-inorganic...

Deep‐Blue Ultralong Room‐Temperature Phosphorescence from Halogen‐Free Organic Materials through Cage Effect for Various Applications

A new concept of cage effect is proposed to promote room-temperature phosphorescence (RTP) property of organic materials. The resulting materials show remarkable deep-blue RTP with CIE coordinates (0.15, 0.09) and lifetime of 3.69 s. The good RTP property is attributed to the strong cage effect including high bending, twisting, and crowding degrees...

Detection of X‐Ray Doses with Color‐Changing Hackmanites: Mechanism and Application

Hackmanites are smart materials having the ability for reversible photochromism upon X-ray exposure. They are highly promising for visualizing X-rays in a simple and portable way. With a comprehensive combination of experimental and computational tools, the mechanism behind X-ray-induced photochromism in hackmanites is revealed. Then, it is shown how...

Thermally Activated Delayed Fluorescence Properties of Trioxoazatriangulene Derivatives Modified with Electron Donating Groups

Donor modified trioxoazatriangulene (TOAT) provides green-to-yellow emission with thermally activated delayed fluorescence (TADF). The mono-modified TOAT shows broad emission spectra, characterized as charge-transfer type emission. By increasing the number of diphenylamine substituents on TOAT, the spectral width of emission becomes narrower, characterized...

Efficient Restraint of Intra‐Cluster Aggregation‐Caused Quenching Effect Lighting Room‐Temperature Photoluminescence

Guided by the strategy of collisional charge transfer tuning, the room-temperature luminescence of [M6I6] cluster-based coordination polymer is effectively increased by replacing Ag(I) with Cu(I). Further heterometallic clusters with various Cu/Ag contents are also prepared to realize wide-range temperature sensing windows with high sensitivities. ...

High Sensitive and Broadband Photodetectors Based on Hybrid PbI2 Nanosheet/CdSe Nanobelt

PbI2 nanosheet/CdSe nanobelt (PbI2 NS/CdSe NB) hybrid device is synthesized for the first time through a one-step method. The PbI2 NS/CdSe NB hybrid device exhibits broadband spectral photoresponse. More importantly, PbI2 NS/CdSe NB hybrid device can promote the effective separation of electron–hole pairs and improve the photoelectric performance. ...

Full‐Color and White Circularly Polarized Luminescence Promoted by Liquid Crystal Self‐Assembly Containing Chiral Naphthalimide Dyes

This paper develops a strategy to regulate white circularly polarized luminescence (CPL) behavior of chiral nematic liquid crystals (N*-LCs) through full-color naphthalimide (NI) derivatives by smart donor–acceptor structure and intramolecular hydrogen bond design. Chiral NI-based dyes as chiral emitters doped into E7 can regulate the white CPL signals...
