Abstract Controlled manipulation of photons/electrons at micro/nanoscale holds the key to development versatile optoelectronics devices. However, current photonics devices are primarily constructed from simple low‐dimensional structures, which suffer limited structural design freedom due planar processing scheme, impeding further performance improvement and functionality upgrades. Herein, first 3D hydrogen‐bonded organic framework (HOF) branched homostructure with spatial positioned multi‐input/output optical channels for photon is reported. The free‐standing HOF homostructures prepared by a steric engineering strategy, involves multinucleation‐assisted growth mechanism. hierarchical Y‐type X‐type exhibit asymmetrical transport behaviors, showing applications in logic gates single or dual ON/OFF functionality, respectively. Moreover, multiple spatially distributed input/output displays asymmetric transport, functions as photonic signal logics. These results offer novel strategy HOF‐based manipulation.

Directional control of photon transport at micro/nanoscale holds great potential in developing multifunctional optoelectronic devices. Here, the switchable anisotropic/isotropic is reported a double-dipole metal-organic framework (MOF) based on radical-controlled energy transfer. Double-dipole MOF microcrystals with transition dipole moments perpendicular to each other have been achieved by pillared-layer coordination strategy. The transfer between double dipolar chromophores can be modulated photogenerated radicals, which permits situ output both polarization (isotropy/anisotropy state) and wavelength information (blue/red-color emission). On this basis, original microcrystal isotropic state displays similar reabsorption losses various directions, while radical-affected anisotropic shows distinct different finally leading transport. These results offer novel strategy for development MOF-based photonic devices tunable performance.

Magnetic resonance imaging (MRI) often employs contrast agents (CAs) to improve the visualization of lesions. Although iron-based oxides have been clinically approved as T2 CAs, various obstacles hindered their widespread commercial use. Consequently, there is a pressing demand for innovative T2-type CAs. Herein, we synthesized an hydrogen-bonded organic framework (Fe-HOF) from Fe-TCPP and explored its potential T2-weighted MRI CA. The Fe-HOF demonstrated superior relaxivity (r2) 32.067 mM–1 s–1 higher r2/r1 ratio 45.25 compared Fe-TCPP. This enhancement may be attributed combination single-atom form Fe3+ with increased radius. Our findings indicate that 6 μmol [Fe]/kg dose significantly improves lesion in scans subcutaneous tumor model mice liver metastasis breast tumor. simplicity Fe-HOF' s structure ensures absence complex metal ions or ligands during synthesis, iron component can metabolized into endogenous pool, resulting remarkable biocompatibility biosafety.
