例句与用法
- create reagents that chemically modify a portion of a molecle without protecting and later having to deprotect ， other reactive sites on the molecule that we do not want to modify
合成能够只对分子的一部分进行选择性反应的化合物，从而不必在反应前先对分子中不想改变的活性位点进行保护并在反应后去保护。 - even though hms can be prepared much more easily than mcm-41 and has certain advantages such as thicker framework walls, superior thermals stability, and a smaller crystalline size . hms have more recently been shown to possess wormhole-like or sponge-like framework structure rather than the long-range hexagonal framework structures characteristics of electrostatically assembled mcm-41 . the wormhole channel motif is a potentially important structure feature for favorable catalytic reactivity, in part, because channel branching within the framework can facilitate access to reactive sites on the framework walls . furthermore the wormhole channel motif suggest that they could serves as ideal hosts for rational nanomanufacturing
1995年，tanev和pinnavaia报道，用中性模板剂合成了一类新的六方介孔固体(hms)，它具有不同于用静电路径合成的mcm-41介孔固体的物理和化学性能，如制备工艺简单、孔壁厚、热稳定性好和晶粒尺寸小等。hms还具有蜂巢或海绵状结构特征，而不象mcm-41那样是长程有序的六方结构。这种蜂巢或海绵状结构特征除有利于催化反应，反应物易于接近孔壁上的反应位外。
