(S)-1,4-二烯丙基-2-甲基吡啶（DAMP）与过量cur的甲醇热反应产生了一种新的同手性三维框架（DAMP）3(Cu4Br4)2(H2O)3(1)，其中Cu4Br4 cubane作为连接节点模拟铁电性中的纯无机作用，以提高剩余极化值，可与肽辅助合成的BaTiO3相媲美。
The methanolothermal reaction of (S)-1,4-diallyl-2-methylpiperazine (DAMP) with an excess CuBr affords a novel homochiral 3D framework (DAMP)3(Cu4Br4)2(H2O)3 (1) in which Cu4Br4 cubane acts as a connecting node to mimic the pure inorganic role in the ferroelectricity to enhance the remnant polarization value which is comparable to that of BaTiO3 synthesized by peptide-assisted synthesis.
