Controllable Synthesis of Monodisperse Hierarchical Porous Carbon Nanorods and Their Derived Superstructures for Supercapacitors

biomass porous nanocarbons has a promising application in electrochemistry. However, controlling the morphology and pore structure presents a formidable challenge. Monodisperse hierarchical porous carbon nanorods (HPCNs) are synthesized from D-xylose, sodium dodecyl sulfate and poly (4-styrenesulphonic acid-co-maleic acid) sodium salt in the hydrothermal condition, followed by activation of KHCO3. Similarly, raspberry-like and spindle-like hierarchical porous nanocarbons can be obtained using sodium laurate and sodium oleate instead of sodium dodecyl sulfate. The hierarchical porous structure facilitates the infiltration and mass transfer process and improves electrochemical performance. In a 6 mol·L-1 KOH electrolyte, the specific capacitance of the HPCNs reaches 302 F·g-1 at a current density of 0.2 A·g-1, and the retention rate is 97% after 6000 charge-discharge cycles at 10 A·g-1. In a pure 1-butyl-3-methylimidazolium tetrafluoroborate electrolyte, a symmetric supercapacitor assembled with HPCNs exhibits a specific capacitance of 125 F·g-1 and an energy density of 39.06 W·h·kg-1 at 0.1 A·g-1. © 2024, The Authors.

Manipulating spatial alignment of donor and acceptor in host–guest MOF for TADF

National science Review 2022年第8期9卷 80-88页

Thermally activated delayed fluorescence（TADF） was achieved when electron-rich triphenylene（Tpl）donors were confined to a cage-based porous metal-organic framework（MOF） host（NKU-111）composed of electron-deficient 2,4,6-tri（pyridin-4-yl）-1,3,5-triazine（Tpt） acceptor as the ligand. The spatially separated donor and acceptor molecules in a face-to-face stacking pattern generated strong through-space charge transfer（CT） interactions with a small energy splitting between the singlet and triplet excited states（～0.1 eV）, which enabled TADF. The resulting Tpl@NKU-111 exhibited an uncommon enhanced emission intensity as the temperature increased. Extensive steady-state and time-resolved spectroscopic measurements and first-principles simulations revealed the chemical and electronic structure of this compound in both the ground and low-lying excited states. A double-channel（T1, T2） intersystem crossing mechanism with S1was found and explained as single-directional CT from the degenerate HOMO-1/HOMO of the guest donor to the LUMO+1 of one of the nearest acceptors. The rigid skeleton of the compound and effective through-space CT enhanced the photoluminescence quantum yield（PLQY）. A maximum PLQY of 57.36% was achieved by optimizing the Tpl loading ratio in the host framework. These results indicate the potential of the MOFs for the targeted construction and optimization of TADF materials.
