Since real-world objects and their interactions are often multi-modal multi-typed, heterogeneous networks have been widely used as a more powerful, realistic, generic superclass of traditional homogeneous (graphs). Meanwhile, representation learning (a.k.a. embedding) has recently intensively studied shown effective for various network mining analytical tasks. In this work, we aim to provide unified framework deeply summarize evaluate existing research on embedding (HNE), which includes but...

Abstract Photochromic materials have drawn enormous attention for their potential applications in optical memory storage and photoswitchable molecular devices. Although great achievements photochromic been fulfilled, it is still a big challenge to realize gated photochromism ready tunable properties. In previous studies, rare examples of are reported. Herein, three triarylethylene derivatives FTrPE‐ o I, ClTrPE‐ I BrTrPE‐ with reversible thermally activated characteristics designed...

Abstract Self-monitoring materials have promising applications in structural health monitoring. However, developing organic afterglow for self-monitoring is a highly intriguing yet challenging task. Herein, we design two molecules with twisted donor-acceptor-acceptor’ configuration and achieve dual-emissive tunable lifetimes (86.1–287.7 ms) by doping into various matrices. Based on photosensitive resin, series of complex structures are prepared using 3D printing technology. They exhibit...

3D printable RTP resins were constructed by doping the emissive guest molecules into methyl methacrylate. Accordingly, 3D-printable real-time temperature sensing and new-concept displays fabricated through DLP printing.

Organic mechanoluminescent (ML) materials possessing photophysical properties that are sensitive to multiple external stimuli have shown great potential in many fields, including optic and sensing. Particularly, the photoswitchable ML property for these is fundamental their applications but remains a formidable challenge. Herein, successfully realized by endowing reversible photochromic an molecule, namely 2-(1,2,2-triphenylvinyl) fluoropyridine (o-TPF). o-TPF shows both high-contrast...

Abstract With the increasing demands of X‐ray detection and medical diagnosis, organic scintillators with intense tunable excited emission have been becoming important. To guarantee absorption, heavy atoms were widely added in reported scintillators, which led to quenching. In this work, we propose a new strategy realize through host‐guest doping strategy. Then absorption centers (host) (guest) are separated. Under excitation, these materials displayed readily emissions ranging from green...

Abstract Thermally activated delayed fluorescence (TADF) materials have attracted great potential in the field of organic light‐emitting diodes (OLEDs). Among thousands TADF materials, highly twisted emitters become a hotspot recent years. Compared with traditional tend to show multi‐channel charge‐transfer characters and form rigid molecular structures. This is advantageous for as non‐radiative decay processes can be suppressed facilitate efficient exciton utilization. Accordingly, OLEDs...

Methods Randomized controlled trials treatment patients diabetes mellitus PubMed, Cochrane Library, Embase, ScienceDirect, Web Science, CNKI, VIP Database, WANFANG Database were searched for from library to September 2023. review authors independently screened studies extracted data. RevMan 5.4 was used direct comparison meta-results. Network...

Recently, luminogens with the aggregation-induced emission characteristic (AIEgens) have received much attention in field of bioimaging and therapeutic applications. However, development AIEgens that are derived from simple core skeleton color tuning for imaging therapy is still a formidable challenge. To address this constraint, we present series cationic based on cyanopyridinium salts (CP1-CP5). The can be facilely prepared by varying aromatic electron donor while fixing group as acceptor...

Strategies for anti-Kasha emissions: in this review, we gave an overview of the recent progress emitters from three aspects: isomerization balancing, excited state balancing and emissive building block combination.

Photochromic polymer is defined as a series of materials based on photochromic units in chains, which produces reversible color changes under irradiation with particular wavelength. Currently, the research progresses, it shows increasing potential applications various fields, such anti-counterfeiting, information storage, super-resolution imaging, and logic gates. However, there paucity published reviews topic polymers. Herein, this review discusses summarizes progress prospects materials,...

Organic room-temperature phosphorescent (RTP) materials, especially with narrowband emission properties, exhibit great potential for applications in display and sensing, but have been seldom reported. Herein, a rare example of the intrinsic blue RTP material is fabricated A series indolo[3,2,1-kl]phenothiazine derivatives, named Cphpz, 1O-Cphpz, 2O-Cphpz, are designed synthesized. Due to their relatively rigid structures, these three compounds showed deep emissions ranging from 396 434 nm...

Data sharing is crucial for open science and reproducible research, but the legal of clinical data requires removal protected health information from electronic records. This process, known as de-identification, often achieved through use machine learning algorithms by many commercial open-source systems. While these systems have shown compelling results on average, variation in their performance across different demographic groups has not been thoroughly examined. In this work, we...

By switching the aggregated state of solid from crystalline to amorphous form, gated transformation photochromism was realized and can be interconverted, demonstrating a new strategy for regulation photochromism.

Despite extensive safety alignment efforts, large language models (LLMs) remain vulnerable to jailbreak attacks that elicit harmful behavior. While existing studies predominantly focus on attack methods require technical expertise, two critical questions underexplored: (1) Are jailbroken responses truly useful in enabling average users carry out actions? (2) Do vulnerabilities exist more common, simple human-LLM interactions? In this paper, we demonstrate LLM most effectively facilitate...
