“…[130] Historically, 1-(bromoacetyl)pyrene (Pyr_2) which is a derivative of pyrene (Pyr_1) has been extensively studied by Daswal and coworkers as a UV-photoinitiator for the copolymerization of styrene with n-butyl acrylate, [131] methyl methacrylate [132] or acrylonitrile in solution (See Figure 4). [133] In these different studies, modification of the substitution pattern of pyrene was determined as strongly influencing the reactivity of the pyrene. [134] Thus, during the free radical polymerization (FRP) of n-butyl acrylate, if Pyr_1 proved to be ineffective in initiating the FRP of acrylates, incorporation of an acetyl group in Pyr_3 and then of a bromoacetyl group in Pyr_2 markedly accelerated the polymerization rate of n-butyl acrylate.…”

Photophysical Behaviour of Novel Quaternary Pyrenoyl Salts and Their Sensitivity Towards Bile Salt Micellization

et al. 2022

View full text Add to dashboard Cite

The present work describes the synthesis and characterization of pyrene derivatives, N-(1-Pyrenoylmethyl)pyridinium bromide (PM-PB) and N-(1-Pyrenoylmethyl)-N,N,N-triethylammonium bromide (PM-TAB). Photophysical behavior of these molecules has been studied in various protic and aprotic solvents. Using steady state uorescence intensity, uorescence anisotropy and dynamic uorescence lifetime studies, the sensitivity of these molecules towards the micellization process of bile salts has been monitored. These derivatives have been effectively used in estimating critical micellar concentration (CMC) of bile salt, sodium deoxycholate (NaDC).
