Provided are bis-quaternary ammonium compounds which are modulators of nicotinic acetylcholine receptors. Also provided are methods of using the compounds for modulating the function of a nicotinic acetylcholine receptor, and for the prevention and/or treatment of central nervous system disorders, substance use and/or abuse, and or gastrointestinal tract disorders.
A light-emitting polymer composition comprising a light-emitting polymer and an ion pair, wherein the ion pair has a negative ion of a specific structure in which one group 13 atom and is bonding to an aryl group having an electron-withdrawing group, or a heterocyclic group having an electron-withdrawing group, directly or through a connecting group; or two or more group 13 atoms, and all the atoms are respectively bonding to an aryl group having an electron-withdrawing group, or a heterocyclic group having an electron-withdrawing group, directly or through a connecting group.
Cyaninedyes are a class of popular imaging probes for diagnosis of cancer and monitoring the process of therapy, especially for cyanines with aggregation-induced emission (AIE). Herein, a series of butterfly-shaped cyaninedyes were synthesized facilely by a two-step reaction and they exhibit higher fluorescence intensity in aggregate states than in dilute solutions, manifesting AIE characteristics
