The compound is useful as a ligand for ruthenium to form an organometallic complex. The complex may be immobilized on an oxidic support to form an active, heterogeneous catalyst for the hydrogenolysis of amides to form amines and optionally alcohols.

The present technology relates to a polymeric material including a plurality of polymer subunits and an active cross-linker, wherein the active cross-linker is covalently linked to the plurality of polymer subunits. The active cross-linker offers a key building block for constructing novel molecular architecture in chemomechanical soft materials and illustrates a new approach to tailor material properties.

A pyridine pyrrole ruthenium coordination complex, a preparation method therefor and use thereof as a catalyst for electrocatalyzing ammonia oxidation to prepare hydrazine is provided. The pyridine pyrrole ruthenium coordination complex takes high-activity metal ruthenium as a central metal ion and compounds containing pyridine pyrrole with electron withdrawing/donating capability as ligands, and thus has relatively high catalytic activity for ammonia oxidation. High conversion rate and highly selective conversion of ammonia can be realized by applying the pyridine pyrrole ruthenium coordination complex to electrocatalytic ammonia oxidation in an organic solvent, with major products including H.sub.2, N.sub.2, N.sub.2H.sub.4.

The present disclosure provides an AS1411 oligonucleotide composite ruthenium complex nanoprobe, and a preparation method and use thereof, and belongs to the technical field of nanoprobes. In the present disclosure, the AS1411 oligonucleotide having the G-quadruplex conformation has a stable structure and can specifically bind with a nucleolin on the membrane of a tumor cell; and RuPEP, the ruthenium complex having the structure of formula 1, has excellent luminescence performance and can be used as a phosphorescent probe to highlight the tumor cell. The AS1411 oligonucleotide composite ruthenium complex nanoprobe provided by the present disclosure has a good property of entering a cancer cell, and can be used as a cancer diagnosis reagent to selectively identify and activate the transportation of an NCL receptor on a surface of the cancer cell to a nucleus, thereby promoting the imaging of the cancer cell.
