Here, the authors present a method for the building of new bicyclic heterometallic cross-linked supramol. polymers by hierarchical unification of three types of orthogonal noncovalent interactions, including Pt(II)-pyridine coordination-driven self-assembly, Zn-terpyridine complex, and host-guest interactions. The Pt-pyridine coordination provides the primary driving force to form discrete rhomboidal metallacycles. The assembly does not interfere with the Zn-terpyridine complexes, which link the discrete metallacycles into linear supramol. polymers, and the conjugation length is extended upon the formation of the Zn-terpyridine complexes, which red shifts the absorption and emission spectra. Finally, host-guest interactions via bis-ammonium salt binding to the benzo-21-crown-7 (B21C7) groups on the Pt acceptors afford the cross-linked supramol. polymers. By continuous increase of the concentration of the supramol. polymer to a relatively high level, supramol. polymer gel was obtained, which exhibits self-healing properties and reversible gel-sol transitions stimulated by various external stimuli, including temperature, K+, and cyclen. Also, the photophys. properties of the supramol. polymers could be effectively tuned by varying the substituents of the precursor ligands. In the experiment, the researchers used many compounds, for example, 3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1Application of 108940-96-1).
3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Application of 108940-96-1
