Unprecedented (3,4)-connected self-catenated network based on V-shaped building blocks

An unprecedented 2D coordination polymer with unique (3,4)-connected self-catenated topology, arising from the parallel interlocking of 1D loop chains via shared binuclear subunits, were prepared from CdII, 5-nitroisophthalic acid and 4,4′-dipyridylamine. The thermal stability and photoluminescence property as well as the photocatalytic performance of 1 were also examined, and the results indicated that 1 shows photocatalytic activity for dye degradation under UV light.
