around the pore outlets. The release of the entrapped [Ru(bipy)3]2+ dye from SN3‐1, SNH2‐2, and SN3‐3 was studied in the presence of selected explosives (Tetryl, TNT, TNB, DNT, RDX, PETN, PA, and TATP). SNH2‐2 showed a fairly selective response to Tetryl, whereas for SN3‐1 and SN3‐3 dye release was found to occur with Tetryl, TNT, and TNB. The uncapping process in the three materials can be ascribed
三种新的杂化门控介孔材料(SN 3 ‐ 1,SNH 2 ‐ 2和SN 3 ‐ 3)装有染料[Ru(bipy)3 ] 2+(bipy = bipyridine)并用不同的四硫富瓦烯(TTF)衍生物封端(具有不同的尺寸和形状并且结合了不同数量的硫原子)已经被制备。材料SN 3 -1和SN 3 -3与TTF衍生物官能化它们的外表面1和3分别通过“点击”化学反应连接,而SNH 2 -2掺入了TTF衍生物2,该衍生物通过酰胺化反应固定在固体上。最终的门控材料已通过标准技术进行了表征。这些固体在乙腈中的悬浮液显示“零释放”,最可能的原因是在孔出口周围形成了致密的TTF网络。SN 3 ‐1,SNH 2 ‐2和SN 3 ‐3中捕获的[Ru(bipy)3 ] 2+染料的释放在选择的炸药(Tetryl,TNT,TNB,DNT,RDX,PETN,PA和TATP)存在下进行了研究。SNH 2 -2显示对特屈儿相当选择性的响应,而对于SN
