Accidentally, it was found that triphenylamine (TPA) from commercial sources shows ultralong yellow-green room temperature phosphorescence (RTP) like commercial carbazole, which however disappears for lab-synthesized TPA with high purity. Herein, we for the first time identify the impurity types that cause RTP of commercial TPA, which are two N , N -diphenyl-naphthylamine isomers. Due to similar molecular polarity and very trace amount (≈0.8 ‰, molar ratio), these naphthyl substituted impurities can be easily overlooked. We further show that even at an extremely low amount (1000000 : 1, mass ratio) of impurities, RTP emission is still generated, attributed to the triplet-to-triplet energy transfer mechanism. Notably, this doping strategy is also applicable to the triphenylphosphine and benzophenone host systems, of which strong RTP emission can be activated by simply doping the corresponding naphthyl substituted analogues into them. This work therefore provides a general and efficient host/guest strategy toward high performance and diverse organic RTP materials.

Metallic conductive 1T phase molybdenum sulfide (MoS 2 ) has been identified as promising anode for sodium ion (Na + ) batteries, but its metastable feature makes it difficult to obtain and its restacking during the charge/discharge processing result in part capacity reversibility. Herein, a synergetic effect of atomic-interface engineering is employed for constructing 2H-MoS 2 layers assembled on single atomically dispersed Fe−N−C (SA Fe−N−C) anode material that boosts its reversible capacity. The work-function-driven-electron transfer occurs from SA Fe−N−C to 2H-MoS 2 via the Fe−S bonds, which enhances the adsorption of Na + by 2H-MoS 2 , and lays the foundation for the sodiation process. A phase transfer from 2H to 1T/2H MoS 2 with the ferromagnetic spin-polarization of SA Fe−N−C occurs during the sodiation/desodiation process, which significantly enhances the Na + storage kinetics, and thus the 1T/2H MoS 2 /SA Fe−N−C display a high electronic conductivity and a fast Na + diffusion rate.

Void-free β-SiC films were deposited on Si（001） substrates by laser chemical vapor deposition using hexamethyldisilane（HMDS） as the precursor. The effect of the time of introducing HMDS, i e, the substrate temperature when HMDS introduced（T_（in））, on the preferred orientation, surface microstructure and void was investigated. The orientation of the deposited SiC films changed from 〈001〉 to random to 〈111〉 with increasing T_（in）. The surface showed a layer-by-layer microstructure with voids above T_（in） ≥ 773 K, and then transformed into mosaic structure without voids at T_（in）= 298 K. The mechanism of the elimination of voids was discussed. At T_（in） =298 K, Si surface can be covered by an ultrathin SiC film, which inhibits the out-diffusion of Si atoms from substrate and prohibites the formation of the voids.

Fine-tuning single-atom catalysts (SACs) to surpass their activity limit remains challenging at their atomic scale. Herein, we exploit p -type semiconducting character of SACs having a metal center coordinated to nitrogen donors (MeN x ) and rectify their local charge density by an n -type semiconductor support. With iron phthalocyanine (FePc) as a model SAC, introducing an n -type gallium monosulfide that features a low work function generates a space-charged region across the junction interface, and causes distortion of the FeN 4 moiety and spin-state transition in the Fe II center. This catalyst shows an over two-fold higher specific oxygen-reduction activity than that of pristine FePc. We further employ three other n -type metal chalcogenides of varying work function as supports, and discover a linear correlation between the activities of the supported FeN 4 and the rectification degrees, which clearly indicates that SACs can be continuously tuned by this rectification strategy.
