Given this, we have proposed a strategy to improve the stability of MOFs by introducing alkali metal K+ capable of coordinating with metal nodes, which finally induces the interpenetrating uranyl-porphyrin framework to connect as a whole (IHEP-9). The stability experiments reveal that the IHEP-9 has good thermal stability up to 400 °C and can maintain its crystalline state in the aqueous solution with pH ranging from 2 to 11. The catalytic activity of IHEP-9 as a heterogeneous photocatalyst for CO2 cycloaddition under the driving of visible light at room temperature is also demonstrated. This induced interpenetration and fixation method may be promising for the fabrication of more functional MOFs with improved structural stability.Circular single-stranded (ss) DNA is an essential element in rolling circle amplification and many DNA nanotechnology constructions. It is commonly synthesized from linear ssDNA by a ligase, which nevertheless suffers from low and inconsistent efficiency due to the simultaneous formation of concatemeric byproducts. Here, we design an intramolecular terminal hybridization strategy to program the ring formation catalytic process of CircLigase, a thermostable RNA ligase 1 that can ligate ssDNA in an intramolecular fashion. With the enthalpy gained from the programmed hybridization to override disfavored entropic factors associated with end coupling, we broke the limit of natural CircLigase on circularization of ssDNA, realizing over 75% yields of byproduct-free monomeric rings on a series of hundred-to-half-kilo-based linear DNAs. We found that this hybridization strategy can be twisted from intra- to intermole
