Carbon dots (CDs) with red-emitting room-temperature phosphorescence (RTP) are rarely reported because of the increasing nonradiative decay excited states and decreasing energy gap between ground states. Herein, we demonstrate a facile strategy for modulating RTP properties CDs in terms donor–acceptor transfer (EnT) CDs-in-zeolite system. Upon tuning heteroatoms (Zn2+, Mn2+) doped aluminophosphate zeolite frameworks, CDs@zeolite composites green red have been prepared via situ hydrothermal...
A rapid one-pot microwave-assisted strategy toward the synchronous preparation of two nano-biomaterials with different scales: lignin nanoparticles and carbon nanodots.
Flexible perovskite solar cells (FPSCs) have attracted great attention due to their advantageous traits such as low cost, portability, light-weight, etc. However, mechanical stability is still the weak point in practical application. Herein, we prepared efficient FPSCs with remarkable by a dynamic thermal self-healing effect, which can be realized usage of supramolecular adhesive. The adhesive, was obtained random copolymerization acrylamide and n-butyl acrylate, amphiphilic, has proper...

High efficiency and mechanical stability are in great demand for commercial applications of the flexible perovskite solar cells (PSCs) portable wearable electronics. Herein, power conversion (PCE) robustness methylammonium (MA)‐free PSCs simultaneously enhanced by incorporating a HPbI 3 additive with optimal content precursor solution. The facilitates an improved morphology crystallinity, as well decreased work function films, leading to device performance. As result, PCEs 20.1% 18.74%...
Bright perovskite nanocrystals with high color purity are promising for high-definition displays; however, their complex postprocessing process limits large-scale production. Using a trace of octylamine to regulate the dynamic balance between surface ligand adsorption and desorption, we develop facile method obtain stable CsPbI3 nanocrystal films that combine excellent optical electrical properties. The additive maintains integrity inhibits formation defects, greatly enhances phase-...
We have developed a new base-promoted intermolecular cascade cyclization reaction of substituted 3-aryl(heteroaryl)-3-chloroacrylaldehydes and tetrahydroisoquinolines in one pot. The provides facile practical synthesis pyrrolo[2,1-a]isoquinolines. A number pyrrolo[2,1-a]isoquinolines were synthesized moderate to high yields (up 97%).
Abstract Interaction between organic molecule and inorganic frameworks can significantly change the photophysical properties of metal‐halides hybrid materials. Here, a family guanidine‐based manganese‐halides is synthesized via supramolecular interactions modulation by adjusting conjugated degree number hydrogen‐bonding donors in templates cations, which further endows intriguing optoelectrical properties. Single‐crystalline mono‐gua (gua = (C(NH 2 ) 3 + )) bigua‐functional group (bigua...

Multicenter photoluminescent CNDs exhibiting excitation-independent cyan and green emissions as well excitation-dependent blue have been prepared by pyrolysis of organo-templated zeolites. Formation origin such multicenter researched.
The ionic liquids (ILs) are reported to perform well in enhancing the oil–solid separation (in pure state or solution) and oil–water processes through interfacial alteration. Herein, behaviors of IL ([C8mim][Br], [C10mim][Br], [C12mim][Br]) cations asphaltenes (from Indonesian asphalt) at interface have been investigated dynamic equilibrium characterizations. tensions (DIFTs) toluene–water systems with without addition ILs measured. It is found that both could diffuse from bulk solution...
The structure regulation of cuprous oxide (Cu2O) has been realized from submicrometric cubes to irregular hollow polyhedrons and truncated octahedrons. It is suggested that the evolution Cu2O exotic morphology are caused by an inside–out Ostwald ripening mechanism in synthetic system, followed induced formation eight (111) six (100) planes a octahedron, while cube with formed quickly via directed attachment weak reduction environment.
