A chiral, fluorescent and self-penetration coordination polymer was synthesized through spontaneous resolution, which showed sensitive detection of picric acid in the aqueous phase.
A novel photocatalyst containing a tetranuclear Cu4 cluster constructed by six 1,2,4-triazole units was reported where two of the six 1,2,4-triazole units show unusual bridging “crevice” coordination mode with their 1- and 2-positioned sp2 N-atoms as symmetrically bridging centers.
