, and 1,4,7,10-tetraazacyclododecane (cyclen). The results revealed that this system will have a potential application value in the fabrication of the smart and adaptive
luminescent materials.
Further research was reported by the same group [63]. A polystyrene backbone
with coumarin units and DBAS moieties as functional groups was prepared by
polymerization reaction. The TPE-containing host molecule was synthesized by
modifying DB24C8 and terpyridine. Then, a cross-linked supramolecular polymer
network with two emission bands was constructed via the orthogonal self-assembly
of host-guest and metal-ligand coordination interactions of functional polymer chain
with TPE-containing host molecule and Zn
2+ (Fig. 22a). The system could exhibit
different fluorescent emission signals at 390 and 460 nm owing to the emission of
coumarin and TPE, and the fluorescence intensities at these two wavelengths could
