本文报道了两种具有开放骨架结构的亚磷酸锌化合物Zn（dabco）0.5（HPO_3）（SCU-18）和Zn_4（Hdabco）_2（CH_3COO）_2（HPO_3）_4（SCU-20），其中dabco = 1，4-二氮杂双环[2.2.2]辛烷。SCU-18具有罕见的3-连接无机骨架，具有手性qtz-h拓扑结构。它包含18元环（18 MR）通道，显示孔隙率和二次谐波产生响应。SCU-20具有包含大的20个MR通道的bnn拓扑结构，其在375 nm处激发时显示出强的蓝色发射。
Presented here are two open-framework zinc phosphites, namely, Zn(dabco)0.5(HPO3) (SCU-18) and Zn4(Hdabco)2(CH3COO)2(HPO3)4 (SCU-20), where dabco = 1,4-diazabicyclo[2.2.2]octane. SCU-18 features a rare 3-connected inorganic skeleton with a chiral qtz-h topology. It contains 18-membered-ring (18 MR) channels displaying porosity and second-harmonic-generation response. SCU-20 has a bnn topology containing large 20 MR channels that shows a strong blue emission as a result of excitation at 375 nm.
