Tb（aspirin）3phen和MCM-41组装体的光谱研究

Study on the spectra of assembly body of Tb （aspirin）3phen and MCM-41

将MCM-41和客体Tb（aspirin）3phen进行组装，采用XRD、IR和PL进行了表征，探讨了主体McM-41和客体Tb（aspirin）1phen间的相互影响。MCM-41焙烧后再进行组装，Tb（aspirin）3phen可增加MCM-41的骨架有序性，充当“二次模板剂”的作用。IR谱图中，Tb（aspirin）3phen-MCM-41组装体在波数1384cm^-1处明显保留了Tb-N键的振动吸收。405nm发射峰强度，L和544nm发射峰强度，ILn的比值I，与McM-41不同的表面环境有关，且McM-41的不同表面环境对配体phen三重态和单重态能级的影响顺序为：MCM-41B外表面〉MCM-41A外表面〉McM-41A内表面。

Assembly system with MCM-41 as a host, and Tb（aspirin）3phen as an active optical guest was synthesized, and characterized by XRD, IR and PL. Interrelationship between the MCM-41 and the Tb（aspirin）3phen was discussed. As a secondary template, Tb（aspirin）3phen increases the framework order of MCM-41 calcined after assembly process. A sharp band at 1384cm^-1 assigned to Tb-N vibration is reserved obviously in the IR spectrum of Tb（aspirin）3phen-MCM-41. The IL/ILn, ratio L where IL is the intensity of 405rim emission peak, and ILn is the intensity of 544nm emission peak, relating to the different surfaces of MCM-41. The influence on the triplet states and single states of phen is： MCM-41B external surface 〉 MCM-41A external surface 〉 MCM-41A inside surface.
