shift不到1550cm-1.
calcium acetate 比较靠谱，但是不一定完全对，一般说来1550的那个峰是salt of
carboxylic acid,到底cation是calcium,sodium,barium 光靠FTIR不一定能确定。 |

发帖数: 95 | 22 我在为含氟的丙烯酸酯/丙烯酰胺类高分子寻找good solvent,发现trifluoroacetic
acid (TFA)的溶解能力特别强，很好用。可是，高分子（白色粉末）溶解于新鲜的TFA
之后溶液由无色透明慢慢变为淡黄色透明。
是不是因为TFA是强酸有所谓的发烟现象？浓盐酸就是淡黄色，因为含有少量杂质Cl2
。另外， 含卤素或含硝基的化合物容易变颜色,是少量变质导致的吗？
谢谢！

查到有这么一句：“olutions of proteins in trifluoroacetic acid prepared in
vacuo
are clear and colourless; on exposure to air, a purple colour develops.”不

there are two relatively new papers below:
especially in one paper, the QDs were used "in vitro" and in the other paper,
different colored QDs were selectively labelled in the core and surface of

or you can refer to Mirkin;s papers, even though he is not in the area of

发帖数: 5044 | 41 非常感谢你！非常有用的信息！我的体系里面含有太多的水，主要的水来自于CMC溶液
。所以最后肯定要把多于的水蒸掉，这样acetylacetone也会一起被蒸发掉哎。
上周末的时候，我已经开始尝试离子交换了，估计明后天就能交换完，希望能把
carboxylic acid上的负电屏蔽掉，避免和Al3+交联。我找到好几篇文献上也是用CMC和
氧化铝混合的，但不知道为啥他们就没有交联的问题。
我之前用polyacrylamide也会交联，估计也是这个原因。

说说碳纳米管表面氧化的两篇文章
这两年碳纳米管表面修饰方面做的文章很多，作者大都claim首先在表面上氧化形成
COOH集团，然后COOH就可以做各种化学反应接上各种好玩的东西了，这方面Tour JM等
同志已经做了很多。
今天我们不谈Tour，专门说说这个氧化的过程。很奇怪的是，很少有人讨论这个氧化的
过程，当然，这个东西也确实不好表征。。。最近的两篇文章倒是对此进行了一些讨论
，讨论的结果也很有意思。当然，这个结果对不对还是仁者见仁智者见智，但是至少可
以给我们一个很好的idea，呵呵。。。

actually the fabrication is based on existing techniques as what I said
"technically not big deal"
SAM of line pattern first, with carboxyl group at end, adsorb stoichiometric
Zn and other ions onto it. Heating at higher temperature and conversion metal
ions into oxides.
repeat this process with only variation of the SAM direction.
this is combination of several ideas & papers
