摘要：

The self-assembly reaction of a multinodal preformed cluster with 1,2-di(pyridin-4-yl)ethane as the organic ligand afforded the 2D cluster polymer (1), {[(WS4Cu4)I-2(dpe)(2)](DMF)(4)}(n). There is a cavity between each two nearby dpe ligands in 1. The [WS4Cu4](2+) units are fixed by I- ions, which is attributed to the multinodal feature of the W-S-Cu secondary building units, and therefore, the cavities in 1 are settled. The NLO properties show that 1 exhibits an optical self-focusing behavior and reverse saturable absorption effects. This work provides us with useful clues to further explore the 2D W-Cu-S-based cluster polymer with cavities.
