The disclosure relates to the technical field of functional nanomaterials, in particular to a fluorescent metal-organic framework superstructure compound, a preparation method and application thereof. The present disclosure provides a method for preparing a fluorescent metal-organic framework superstructure compound, comprising the steps of: providing a microfluidic mixing device; injecting a soluble rare earth salt solution from the first feeding pipe 1; injecting an oil phase solution from the second feeding pipe 2; forming droplets of the rare earth salt solution in the mixing channel 4; then subjecting the droplets to a coordination reaction with an organic ligand solution to obtain the fluorescent metal-organic framework superstructure compound. The preparation method provided by the present disclosure can prepare the fluorescent metal-organic framework superstructure compound in the form of a sphere which is self-assembled from MOFs nanorods, and the particle size distribution of the sphere is uniform.

The present invention relates to supramolecular biomedical polymers comprising quadruple hydrogen bonding units and to a process for preparing such a supramolecular biomedical polymer and porous biomedical implants thereof. The supramolecular biomedical polymers are particularly suitable for the production of porous biomedical implants that need high strength, elasticity, durability, and slow biodegradation, e.g. medical implants for living tissue regeneration within a mammal, such as the treatment of cardio-vascular diseases, medical prolapses, and hernias.
