TICT荧光探针法研究甲基化的β-环糊精空腔微环境

p-dimethylaminobenzonitrile (DMABN), a typical dual fluorescent flurophor (TICTflurophore), was used as fluorescent probe. The microenviromental property of twelve methyl modified β-cyclodextrin(methyl β-CD) was compared with that of β-cyclodextrin (β-CD). Results showed that the polarity of the cavity of methyl β-CD is lower than that of β- CD, and the capacity of methyl β-CD inclusion with DMABN is stronger than that of β-CD inclusion with DMABN

动力学室温磷光法研究外磁场效应对不同脂肪醇/α-溴代萘/β-环糊精包络物生成速度的影响

用动力学室温磷光法考察了外加磁场效应（MFEs）对不同脂肪醇、α-溴代萘（α－BrNp）、β-环糊精（β-CD）包络物生成速度的影响．结果表明：MFEs使正构醇、α-溴代萘、β-CD包络物的生成速度增加，而异构醇则相反

萘和正丁醇存在下β－环糊精诱导1－溴萘室温磷光的研究

β-环糊精存在下直链脂肪醇诱导1-溴萘室温磷光光谱研究

研究了β-环糊精（β-CD）溶液中直链脂肪醇（A）诱导1-溴萘（1-BrN）的室温磷光光谱性质．结果表明，三元包络物中1-BrN分子的磷光起初随醇中碳原子数的增加而增强，正戊醇对磷光呈现最大的敏化作用，随后从正己醇至正辛醇，磷光强度逐渐下降．测定了包络物组成和稳定常数，发现1-BfN和A：β-CD包络物的结合强度是三元包络物磷光强弱的决定性因素，并从三元包络物可能的结构解释了醇分子大小对室温磷光的影响

1-溴萘—β-环糊精—阴离子表面活性剂三元包合物的室温磷光

在β-环糊精(β-CD)溶液中,加入阴离子表面活性剂(AS)可诱导1-溴萘(1-BrN)发射强的室温磷光(RTP).组成测定表明溶液中形成了稳定的1:1:1/1-BrN:β-CD:AS三元包合物.光谱和溶液表面张力分析显示阴离子表面活性剂的疏水性烷基链有一部分被包合在β-CD空腔内,未被包合部分则绕曲在β-CD腔口处从而为空腔内1-BrN分子的磷光提供了有效保护.因该三元包合物带有阴离子极性头基,其沉淀可均匀分散在溶液中,形成了稳定的乳状液.得到了稳定的RTP

Studies on effects of external magnetic field on the formation rate of complex of alpha-bromonaphthalene/beta-cycoldextrin and different aliphatic alcohols by kinetic room-temperature phosphorimetry

The effects of external magnetic field on the formation kinetic behavior of the inclusion complex of alpha-bromonaphthalene and beta-cycoldextrin with different aliphatic alcohols has been investigated by kinetic room-temperature phosphorimetry, The effects of external magnetic field on the inclusion complex formation initial rate were positive for n-alcohols, but the negative results were obtained for iso-alcohols
