摘要

In this study, we estimated the color-transition behavior of a polydiacetylene (PDA) vesicle system for butylamine detection in an EtOH-water mixed solvent. The effect of the EtOH concentration in the vesicle system on the color transition of PDA was measured. 10,12-Pentacosadiynoic acid (PCDA) was used to form the PDA vesicle by sonication and photopolymerization. The results show that the vesicle formation of PCDA was accomplished with up to 13 wt % EtOH. As the concentration of EtOH increased from pure water (0 wt %) to 13 wt %, a larger size vesicle was formed, with the color transition occurring at a lower temperature and with a lower amount of butylamine. The color of the PDA vesicle solution started to change at 3 mM butylamine with pure water as the solvent and at 2.5 mM butylamine with 10 wt % EtOH. (c) 2019 Wiley Periodicals, Inc. J. Appl. Polym.
