Target Dyes Fl,F3 And F5 Display High Selectivity And Sensitivity Toward Zn2+ In Solvents (Such As Etoh,Etoh/pbs Buffer) In The Presence Of Competitive Ions (K+,Na+,Ni2+,Pb2+,Mn2+,Mg2+,Hg2+,Cu2+,Cd2+,Cr3+,Fe3+). Sensing Property For Zn2+ Was Studied By Uv-Visible,Fluorescence Spectrophotometric Analyses And Job'S Plot Analyses. F1,F3 And F5 For Zn2+ Detection Revealed Extremely Low Detection Limit (67.2 Nm),High Anti-Interference Ability,And The Immediate Response. Furthermore,Inverted Fluorescence Microscopy Imaging Experiment Were Also Investigated,The Results Demonstrated That The Probes Have Well Cell Membrane Permeability And Hypotoxicity. Simultaneously,Due To The Ability To Adapt A Wider Range Of Ph,The Probes Could Also Image Zn2+ In Live Cells With Remarkable Fluorescence Variation And Provide A New Method To Visualize Monitoring In Live Cells.

专利号:US-2012305484-A1 优先权日:2011-06-03 标题 :Thermally Rearranged (TR) Polymers as Membranes for Ethanol Dehydration 发明人:FREEMAN BENNY D; PAUL DONALD R; CZENKUSCH KATRINA; RIBEIRO JR CLAUDIO P; BA CHAOYI 权利人:FREEMAN BENNY D; PAUL DONALD R; CZENKUSCH KATRINA; RIBEIRO JR CLAUDIO P; BA CHAOYI; UNIV TEXAS 摘要:Synthesis and use of a new class of polymeric materials with favorable separation characteristics for the dehydration of ethanol and other organic solvents is described herein. The thermally rearranged (TR) polybenzoxazole (PBO), polybenzimidazole (PBI) and polybenzothiazole (PBT) membranes of the present invention can be used for the dehydration of ethanol during processing to fuel grade biodiesel by either pervaporation or vapor permeation. The unique microstructure of the membranes provides excellent separation characteristics, and this, coupled with their inherent thermal and chemical stability, enables their usage in other separations, such as the dehydration of other organic solvents.
