In this thesis, we did modifications of alkyl groups upon benzyl fluorophosphonate. In order to study the influence of alkyl length and steric effect on activity and selectivity of probes, we synthesized benzyl fluorophosphonate recognition heads with modifications including ethyl, butyl, octyl and cyclohexyl. By way of connecting different kinds of tag like azido group, biotin and rhodamine with recognition heads separately through a higher hydrophilic ethylene glycol derived linker, a series of benzyl fluorophosphonate probes were made up. And they will apply to various biological testing strategies.

在本论文中，我们以苯甲基氟化磷酸酯为基础，於其上进行一系列烷基之修饰，为了探讨烷基长度与空间立体性质对於探针活性及选择性的影响，我们合成了包含乙烷基、丁烷基、辛烷基以及环己烷基修饰的苯甲基氟化磷酸酯辨识端，并藉由具较高亲水性的聚乙二醇衍生连接桥结合三种不同的发报端，分别有叠氮基团、生物素及萤光基团来构成不同的化学探针组合，这一系列苯甲基氟化磷酸酯类化学探针将可被应用於不同的生物测试策略。

Dialkylamine, which is an e-donor, was introduced at the C(4') or C(7) positions in 3HF resulting in similar ESICT/ESIPT dual emission. Even the net dipole moment, the orientation of which is affected by the CT effect, is expected different. Dialkylamine attached at both C(4') and C(7) positions in 3HF, of which the net dipole moment may be associated with the interplay between two charge-transfer systems, displayed different photo behaviors.

在3-hydroxyflavone的4'及7号位置分别修饰担任电子与体的二烷基胺类，在光谱上会观察到两种不同萤光波长，分别属於ESICT和ESIPT，但若同时修饰二烷基胺类，在不同极性溶剂下，会只有一个 ESIPT 的萤光。

Pt nano particles decorated with nafion ionomers were synthesized and used as electrocatalyst in proton exchange membrane fuel celldue to plentiful proton channels provided by the enwrapping polymers.Then decorated Pt particles were deposited on carbon nanotubes,which enwind each other into interconnect nets and form the framework of the catalyst layer for PEM fuel cell.

介绍了Nafion聚合物作为修饰离子，合成具有原位质子导电能力的纳米Pt颗粒；TEM分析显示Pt颗粒的平均粒径为4nm，颗粒之间界限明显，分散状态良好；将这种离子导体修饰的纳米Pt沉积到纳米碳管表面作为质子交换膜燃料电池催化电极，纳米碳管相互缠绕在催化层形成交联的电子通道。

Thiol groups were good to be used in functionalizing gold nanoparticles, and ester bond formation and breakage played the major role in this research. Thioctic acid and 11-mercapto-1-undecanol were used to functionalize the gold nanoparticles and form ester bond by using the carboxylic acid group on thioctic acid and the hydroxyl group on 11-mercapto-1-undecanol. Concentrated sulfuric acid was used to be the catalyst in this reaction, and sodium hydroxide was added for the proceeding of the reverse reaction.
