The first 3D dimensional polymeric cluster 〓(8) has been synthesized though solid state reaction, the X-ray structural analysis showed that the three-dimensional framework of 8 has a very high degree of symmetry with three mirror planes and one four rotation axis in I4/mmm space group, and composed of two building blocks 〓 and 〓 bridged by S-Cu〓 and Cu〓-Cl bond.

化合物6非线性折射值n〓为-9.3×10〓m〓·w〓，显示自散焦性质，与我们以前观察到的现象相反，这可能是配体作用造成的；非线性吸收值α〓 1.23×10〓m·w〓，表现出较强的非线性吸收效应。

Crystallographic, biochemical, and mutagenic experiments show that the unliganded PDZ domains are inhibitory and suggest that OMP binding per se is sufficient to stabilize the relaxed conformation and activate DegS.

检晶仪，生化和诱变实验表明未连接配体的PDZ区域处于抑制状态，这说明OMP的结合足够维持R态的稳定并激活DegS。
