Abstract The development of advanced materials for information encryption with time-dependent features is essential to meet the increasing demand on security. Herein, smart orthogonal and temporal properties are successfully developed based a dynamic assembly-induced multicolour supramolecular system. Multicolour fluorescence, including blue, orange even white light emissions, achieved by controlling assembly pyrene derivatives tailoring solvent composition. By taking advantage tuneable...
Covalent organic framework nanosheets (CONs), fabricated from two-dimensional covalent frameworks (COFs), present a promising strategy for incorporating atomically distributed catalytic metal centers into well-defined pore structures with desirable chemical environments. Here, series of CONs was synthesized by embedding single cobalt sites that were then evaluated photocatalytic carbon dioxide reduction. A partially fluorinated, cobalt-loaded CON produced 10.1 μmol monoxide selectivity 76%,...
Dynamic control over molecular emission, especially in a time-dependent manner, holds great promise for the development of smart luminescent materials. Here we report series dynamic multicolor fluorescent systems based on time-encoded locking and unlocking individual vibrational emissive units. The intramolecular cyclization reaction driven by adding chemical fuel acts as lock to decrease conformational freedom units, thus varying fluorescence wavelength, while resulting chemically locked...
Soft porous crystals combine flexibility and porosity, allowing them to respond structurally external physical chemical environments. However, striking the right balance between sufficient rigidity for porosity is challenging, particularly molecular formed by using weak intermolecular interactions. Here, we report a flexible oxygen-bridged prismatic organic cage molecule, Cage-6-COOH, which has three pillars that exhibit "hinge-like" rotational motion in solid state. Cage-6-COOH can form...
Energy-structure-function (ESF) maps can aid the targeted discovery of porous molecular crystals by predicting stable crystalline arrangements along with their functions interest. Here, we compute ESF for a series rigid molecules that comprise either triptycene or spiro-biphenyl core, functionalized six different hydrogen-bonding moieties. We show positioning sites, as well number, has profound influence on shape resulting maps, revealing promising structure-function spaces future...
Developing photoresponsive circularly polarized luminescence (CPL) materials is an essential step for biosensing and biomedical applications. However, fabricating CPL assemblies rooted in the chirality amplification transmission of molecular building blocks, which simultaneously show photo-controllable signals, remains challenging. Herein, a block containing overcrowded-alkene core bis-PBI (MPBI) was designed. Importantly, enantiopure MPBI can self-assemble into well-organized nanofibers via...
Despite the great progress in research on molecular carbons containing multiple helicenes around one core, realizing stereoselectivity of more cores is still a challenge. Herein, carbon C204 featuring 12-fold [5]helicenes four was successfully constructed by using nine perylene diimide (PDI) units, and exhibits good solubility stability. 256 possible stereoisomers caused [5]helicenes, we only obtained pair enantiomers with D3 symmetry. There are pairs symmetry, namely 7A, 7B, 7C 7D....
Abstract Dynamic control over molecular emission, especially in a time‐dependent manner, holds great promise for the development of smart luminescent materials. Here we report series dynamic multicolor fluorescent systems based on time‐encoded locking and unlocking individual vibrational emissive units. The intramolecular cyclization reaction driven by adding chemical fuel acts as lock to decrease conformational freedom units, thus varying fluorescence wavelength, while resulting chemically...
Evaporation induced self-assembly is used to prepare nanocomposites of a conjugated polymer and inorganic semiconductor. The nanostructured composite has significantly improved sacrificial hydrogen evolution rates compared the individual components.
Abstract Ethyl acetate is an important chemical raw material and solvent. It also a key volatile organic compound in the brewing industry marker for lung cancer. Materials that are highly selective toward ethyl needed its separation detection. Here, we report trianglimine macrocycle ( TAMC ) selectively adsorbs by forming solvate. Crystal structure prediction showed this to be lowest energy solvate available. This leaves metastable, “templated” cavity after solvent removal. Adsorption...

Organic crystals that can respond to external stimuli and exhibit fluorescence changes have drawn increasing attention recently as their potential applications in intelligent displays, optical data storage, anticounterfeiting, bioimaging, sensors. Herein, we synthesized two new organic compounds based on frameworks of anthracene pyridine groups: 4-(anthracen-9-yl) (AN9P) 4-(anthracen-2-yl) (AN2P). Both compounds, solutions solid states including polycrystals single crystals, display...
The packing of organic molecular crystals is often dominated by weak non-covalent interactions, making their in-situ rearrangement under external stimuli challenging to understand. We investigate a pressure-induced single-crystal-to-single- crystal (SCSC) transformation between two polymorphs 2,4,5-triiodo-1H-imidazole using machine learning potentials. This process involves the halogen and hydrogen bonds combined with proton transfer within complex solid- state system. developed strategy...
The physical and chemical properties of molecular crystals are a combined function structure the crystal packing. Specific packings can enable applications such as pharmaceuticals, organic electronics, porous materials for gas storage. However, to design materials, we need predict both resulting properties, this is expensive using traditional computational methods. Machine-learned interatomic potential methods offer major accelerations here, but prediction remains challenging due weak...
