Uses

Hexyltrimethylammonium bromide (HTAB) can be used as: A phase transfer catalyst to synthesize polyether via polycondensation of α, α′-dichloro-p-xylene with 2,2-bis(4-hydroxyphenyl)propane. A reagent in the preparation of ZSM-5 zeolites to tune ZSM-5 particles with a scroll-like shape and hierarchical pores. A surface-active agent to create the hydrophobic environment around metal nanoparticles (MNPs) even in water. This technique is highly suitable for using MNPs as electron-counting components in biosensors.

Purification Methods

Recrystallise it from acetone. It is extremely hygroscopic. [McDowell and Kraus J Am Chem Soc 73 2170 1951, Beilstein 4 IV 710.]

Nanoparticles with Near-Infrared Emission Enhanced by Pillararene-Based Molecular Recognition in Water

Here we report the unprecedented preparation of nanoparticles with near-infrared (NIR) emission enhanced by host-guest complexation between a water-soluble pillar[5]arene (WP5) and a cyanostilbene derivative (1) in water. Amphiphilic 1 self-assembles in water to form nanoribbons with relatively weak NIR emission at low concentrations. However, after addition of equimolar WP5, these nanoribbons transform into nanoparticles with stronger NIR emission due to the formation of a supramolecular amphiphile and host-guest complexation-enhanced aggregation. These nanoparticles show pH responsiveness, and collapse after treatment with acid. More importantly, these nanoparticles can be used in living cell imaging.

Photoprocesses on Colloidal Clay Systems. 2. Quenching Studies and the Effect of Surfactants on the Luminescent Properties of Pyrene and Pyrene Derivatives Adsorbed on Clay Colloids

The cationic fluorescent probe trimethylammonium bromide (PN+) is adsorbed by the colloidal particles of the clay minerals montmorillonite and kaolin.The emission spectrum, polarization of fluorescence measurements, and transient fluorescence decay characteristics of PN+ are used to study the nature of its adsorbed state.Quaternary ammonium surfactants of varying hydrocarbon chain length cause a rearrangement of the PN+ molecules on the surface and decrease its interaction with the mineral surface.Quenching studies with nonionic andcationic molecules indicate that diffusion on the surface of montmorillonite is reduced below that observed in aqueous solution while the apparent rates obtained with kaolin particles are increased.Montmorillonite particles with a surfactant bilayer surrounding their surfaces are formed by the addition of an excess amount of surfactant to the colloid.The emission spectrum and the steady-state quenching studies yield information on the location of pyrene on these particles, as well as on the nature of the colloidal particles.
