This work afforded a feasible strategy via inorganic-organic combination to distinguish trace RH and improved the operation stability of 2D material-based sensors, simultaneously demonstrating realistic monitoring applications of exhaled gas detection and distance variation of moisture-emitting objects.Benefiting from superior programmability and good biocompatibility, DNA nanomaterials have received considerable attention with promising prospects in biological detection applications. However, their poor stability and operability severely impede further development of the applications of DNA nanomaterials. Here, a thermally stable DNA nanomesh structure is integrated into a microfluidic chip. The specificity of the nucleic acid microfluidic capture device could reach the single-base mismatch level while capturing the ssDNA sample. The microfluidic chip provides a closed environment for the DNA nanomesh, giving the device excellent storage stability. After 6 months of storage at room temperature, the device still has a specific capture function on ssDNA samples with low concentration. The specific nucleic acid microfluidic capture device can be applied to the enrichment of ctDNA in the future and contribute to the early diagnosis of cancer.This work describes the construction of a novel planar chiral [2.2]paracyclophane-based thermally activated delayed fluorescence (TADF)-active molecule with circularly polarized luminescence (CPL). The combination of the bulky planar chiral phenoxazinephane (PXZp) donor based [2.2]paracyclophane and triazine acceptor enables the highly efficient luminescence performances and excellent CPL properties. The enantiomers exhibit excellent TADF activities, the energy difference (ΔEST) between singlet and triplet of the molecule is only 0.03 eV. Notably, through solution-process, a yellow CP-OLEDs based on the molecule as the emitting layers displays high maximum brightness (Lmax) up to 34 293 cd m-2, maximum external quantum efficiency (EQEmax) up to 7.8% and remarkable CP-EL signal with gEL factor up to 4.6 × 10-3.Carbon capture from industrial effluents such as flue gas or natural gas mixture (cf. landfill gas), the primary sources of CO2 emission, greatly aids in balancing the environmental carbon cycle. In this context, the most energy-efficient physisorptive CO2 separation process can benefit immensely from improved porous sorbents. Metal organic frameworks (MOFs), especially the ultramicroporous MOFs, built from readily available small and rigid ligands, are highly promising because of their high selectivity (CO2/N2) and easy scalability. Here, we report two new ultramicroporous Co-adeninato isophthalate MOFs. They concomitantly carry basic functional groups (-NH2) and Lewis acidic sites (coordinatively unsaturated Co centers). They show good CO2 capacity (3.3 mmol/g at 303 K and 1 bar) along with high CO2/N2 (∼600 at 313 K and 1 bar and ∼340 at 303 K and 1 bar) selectivity, working capacity, and smooth diffusion kinetics (Dc = 7.5 × 10-9 m2 s-1). The MOFs exhibit good CO2/N2 kinetic separation under both dry and wet conditions with a smooth breakthrough profile. Despite their well-defined CO2 adsorption sites, these MOFs exhibit only a moderately strong interaction with CO2 as evidenced from their HOA values. This counterintuitive observation is ubiquitous among many MOFs adorned with strong CO2 adsorption sites. To gain insights, we have identified the binding sites for CO2 using simulation and MD studies. The radial distribution function analysis reveals that despite the amine and bare-metal sites, the pore size and the pore structure determine the positions for the CO2 molecules. The most favorable sites become the confined spaces lined by aromatic rings. A plausible explanation for the lack of strong adsorption in these MOFs is premised from these collective studies, which could aid in the future design of superior CO2 sorbents.
