文摘

The implementation of four bidentate building blocks into a high-denticity linker with a flexible spacer leads to a predisposed ligandthat allows one to direct the self-assembly of 1D functionalcoordination polymers. This is illustrated by the assembly undermild conditions of the luminescent metal-organic framework[Tb(Htpabn)]·14H₂O_{ges/entities/infin.gif">} (1; H₄tpabn = N,N,N',N'-tetrakis[(6-carboxypyridin-2-yl)methyl]butylenediamine). The X-ray crystal structureshows that the monoprotonated Htpabn binds two equivalentlanthanide ions to form a one-directional staircase chain. The highligand denticity prevents solvent coordination and leads to a highluminescence quantum yield (Q = 39%), which is maintained aftersolvent removal.
