We have reported NAND logic fluorophore recognized alkaline earth metal, salts in 1998. This research was a construction of new type multi input logical recognition system having optical output.The target guest molecule were alkaline earth metal and transition metal guests. Synthesized a novel nitrogen containing hetero-aromatic host, pyridopimdazoquionxaline(PIQ) and pyridoimidazopyiradino-phenanthroline (PIPPh) ring. These hosts were complexization with transition metal cations, in the case of PIPPh, some complex species was existed.Multi guest recognition host having 12crown4 ether side arm PIQ (PIQ-crown) was newly synthesized. PIQ-crown was made a NAND logical fluorescence quenching output by the Ca(SCN)_2 and Ba(SCN)_2, this behavior was similarly we reported PIP-crown derivatives, moreover, made an OR logic by transition metal cation. Multi guest recognition with transition metal cation and alkaline earth metal thiocyanate gave very interesting results. Gave many logical calculated output signals by combinations of adding guest. For example, The addition of Zn(C10_4)_2 and alkaline earth metal thiocyanate were combined with OR, NAND, AND operations, Zn(SCN)_2 and alkaline earth metal thiocyanate were combined with QR, AND, NAND operations.In conclusion, new type multi logical recognition host PIQ-crown was synthesized. This host gives many interesting logical output by the addition of multi guest inputs.

我们在1998年报道了与非逻辑荧光团识别碱土金属盐。本研究构建了一种新型的具有光输出的多输入逻辑识别系统，目标客体分子为碱土金属和过渡金属客体分子。合成了一种新型的含氮杂环主体化合物吡啶并咪唑并喹喔啉（PIQ）和吡啶并咪唑并菲咯啉（PIPPh）环。这些主体与过渡金属阳离子发生络合反应，在PIPPh的情况下，存在一些络合物物种，新合成了具有12冠4醚侧臂的多客体识别主体PIQ（PIQ-冠）。PIQ-冠醚与Ca（SCN）_2和Ba（SCN）_2形成与非逻辑荧光猝灭输出，这种行为与我们报道的PIP-冠醚衍生物类似，而且与过渡金属阳离子形成或逻辑荧光猝灭输出。过渡金属阳离子和碱土金属硫氰酸盐的多客体识别得到了非常有趣的结果。通过添加客户机的组合，给出了多个逻辑计算输出信号。如Zn（C10_4）_2与碱土金属硫氰酸盐的加成反应与OR、NAND、AND运算相结合，Zn（SCN）_2与碱土金属硫氰酸盐的加成反应与QR、AND、NAND运算相结合，合成了新型多逻辑识别主体PIQ-冠醚。这个主机通过添加多个客户机输入提供了许多有趣的逻辑输出。
