资源简介：
A new three-dimensional porous metal–organic
framework,
JUC-119, constructed by a pyrene-based dendritic organic linker, H8TIAPy (H8TIAPy = 1,3,6,8-tetrakis(3,5-isophthalic
acid)pyrene), and Eu(III) has been synthesized successfully. JUC-119
shows unexpected stability under a wide range of basic conditions
from 0 to 0.01 M NaOH. Furthermore, with two carboxyl groups uncoordinated
in each ligand, the crystals of JUC-119 show deprotonation-triggered
Stokes shift fluorescence under basic conditions. As the concentration
of base increases from 0 to 0.01 M NaOH, the luminescence emission
of JUC-119 becomes gradually red shifted from 455 to 485 nm. In addition,
the Stokes shift shows a good linear relationship to −log[OH–], which makes JUC-119 promising for base sensing.
