AI Article Synopsis
- The text discusses diacetylenic lipids, focusing on how the photoresponsive 1,3-diyne function is integrated into the hydrocarbon chain of amphiphiles relative to the headgroup.
- It highlights the creation of a polydiacetylene network through polymerization of liposomes when exposed to UV light, emphasizing its role in sensing applications.
- Additionally, it mentions the synthesis of cationic diacetylenic amphiphiles with triple bonds near charged nitrogen and explores their polymerization capabilities under specific aggregative conditions, analyzed through NMR and Langmuir trough experiments.
Article Abstract
In the wide panorama of diacetylenic lipids, the photoresponsive conjugated 1,3-diyne function is usually encased into the hydrocarbon chain of the amphiphile at a variable distance from the headgroup. Therefore, the polydiacetylene network obtained by polymerization upon UV irradiation of the corresponding liposomes, exploited as sensing function, is embedded in the hydrophobic region of liposomes. Structurally related cationic diacetylenic amphiphiles featuring the conjugated triple bonds proximate to charged nitrogen were synthesized and evaluated in their ability to polymerize under aggregative conditions. The occurrence of polymerization only in certain aggregating conditions was rationalized by nuclear magnetic resonance (NMR) and Langmuir trough experiments.
