A triphenylamine-based aggregation-enhanced emission probe for viscosity and polarity analysis of lubricating oils

Abstract

Lubricating oil offers abundant information about the operating state of machine. In this work, a donor-acceptor aggregation-enhanced emission fluorescent molecule, (Z)-4-(1-cyano-2-(4-(diphenylamino)phenyl)vinyl)benzonitrile (CPA-TPA), was synthesized to investigate its function to sense...

Fluorescent probes based on acridine derivatives and their application in dynamic monitoring of cell polarity variation

“…[1][2][3][4] As complex parameters, polarity is affected by hydrogen bonds, dipoles, polarizability, etc., and viscosity is involved in various bioprocesses. [5][6][7][8] In addition, some diseases such as cancer and Alzheimer's disease have been authenticated to be related to polarity and viscosity. [9][10][11][12] Lipid droplets are the main storage sites for intracellular lipids.…”
