Manipulation of persistent charges in semiconductor nanostructure is the key point to obtain quantum bits towards the application of quantum memory and information devices. However, realizing persistent charge storage in semiconductor nano‐systems is still very challenge due to the disturbance from crystal defects and environment conditions. Herein, the two‐photon persistent charging induced long‐lasting...
Covalent organic frameworks (COFs) offer a desirable platform to explore multichoromophoric arrays for photocatalytic conversion. Symmetric arrangement of choromophoric modules over π‐extended frameworks enhances exciton delocalization while impairing excitation density and accordingly photochemical reactivity. Herein, a photoisomerization‐driven strategy is proposed to break the excited‐state symmetry...

In article number 2304146, Kui‐juan Jin and co‐workers report the novel photoinduced insulator‐metal and superconducting‐like phase transitions in the infinite‐layer NdNiO2 film, bringing forward a unique way to manipulate the electronic correlation with photons and trigger intriguing quantum phase transitions.
The quantum phase transition caused by regulating the electronic correlation in strongly correlated quantum materials has been a research hotspot in condensed matter science. Herein, a photon‐induced quantum phase transition from the Kondo‐Mott insulating state to the low temperature metallic one accompanying with the magnetoresistance changing from negative to positive in the infinite‐layer NdNiO...
Exsolution of stable metallic nanoparticles for use as efficient electrocatalysts has been of increasing interest for a range of energy technologies. Typically, exsolved nanoparticles show higher thermal and coarsening stability compared to conventionally deposited catalysts. Here, A‐site deficient double perovskite oxides, La2‐xNiRuO6‐δ (x = 0.1 and 0.15), are designed and subjected to low‐temperature...
Two‐dimensional covalent organic frameworks (2D COFs) offer a designable platform to explore porous polyelectrolyte frameworks with periodic ionic skeletons and uniform pore channels. However, the crystallinity of ionized 2D COF is often far from satisfactory as the electrostatic assembly of structures impedes the ordered layered arrangement. Here, a multivariate synthetic strategy to synthesize a...
Ruddlesden–Popper (RP) metal halide perovskites are considered as promising optoelectronic materials due to their good environmental stability and desirable optoelectronic properties. However, the phase composition and ordering in the deposited film, with a fixed ratio of large organic spacer cation in the precursor solution, are hard to be further tailored for specific optoelectronic applications...
Doped 2,2′,7,7′‐tetrakis(N,N‐di‐p‐methoxyphenylamine)‐9,9′‐spirobifluorene (spiro‐MeOTAD), which acts as a hole‐transporting layer (HTL), endows perovskite solar cells (PSCs) with excellent performance. However, the intrinsically hygroscopic nature of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) dopants also aggravates the moisture instability of PSCs. In this work, the origins of the moisture...
In article number 1903254, Jia Guo, Yu Chen, Huixiong Xu, and co‐workers fabricate ultrasmall dual‐targeting iridium nanocrystals modified with tumor cell‐targeting RGD peptides and nucleus‐targeting TAT proteins for effective tumor localization and nucleus targeting, inducing prominent sensitized tumor radiotherapy.
Prominent tumor‐cell nucleus targeting of radiosensitizer substantially affects the therapeutic consequence of advanced tumor radiotherapy via lethal nucleus DNA damage. Herein, ultrasmall iridium nanocrystals (Ir NCs, <5 nm) are constructed for efficient tumor‐specific photonic hyperthermia‐synergized radiotherapy. To endow the NCs with qualified cell nucleus‐targeting performance, polyethylene...
On the basis of the gel effect of the living RAFT (Reversible Addition‐Fragmentation Chain Transfer) polymerization, magnetic nano‐sponges with ultrasoft PAA net‐like shells are prepared and then used for enriching the entire proteins from real biological samples with ultrahigh capacity. In addition, the immobilized enzyme Cyt c or HRP surprisingly show much higher catalytic activity than free enzymes...
