Low-heating solid state synthetic reactions of cyclopeantadienyl organolanthanide complexes

A novel and simple one-step,solid state reaction of multicomponent systems has been developed to synthesize cyclopentadienyl-containing organolanthanide complexes,in which the effects of the coordinated solvent molecules and the nature of the reactants were also studied.We also studied the solid state decomposition reaction of Cp2 YbPz(HPz),and the formation of [CpYb(Pz)2|2 may indicate that the constrained environment in solid state can lead to a novel chemical transformation,with product selectivity possibly different from that in the liquid phase.     

Fluorescence quenching effect of metal ions for α,α''''-diamine containing conjugated polymers in solid films

The fluorescence quenching effect of the conjugated polymers P1 and P2 (the molecular recognitions are twisted 2,2'-bipyridine (bpy) and planar 1,10-phenanthrolin (phen), respectively) films upon the addition of metal ions has been studied. And the results showed that P2 exhibited stronger fluorescence quenching ability upon the addition of both transition metal ions and main group metal ions compared with that of P1. The 20° twist angle between the two consecutive pyridine rings of bpy unit in the P1 main chain is the reason for the weaker fluorescence quenching ability compared with P2, in which the planar phen unit can chelate with metal ions relatively freely without the conformational transition. So P2 is a kind of material with better properties for solid film devices, such as sensors for metal ions recognition.

采用光镜、透射电镜及固体荧光测定考查了用自制偶联剂CGE（N）－R型处理前、后的牙本质表面状态。光谱下显示，牙本质小管及其小孔，以脱钙后更为清晰。电镜下能直接观察到偶联剂晶体被牙本质吸附的状态。荧光光谱测定结果表明：偶联剂处理后的牙本质的荧光峰位红移达11－31nm，由此给出了偶联剂与牙本质之间化学结合的明确信息。为牙本质与偶联剂结合机理模式的建立提供了有力的实验依据。
