Hazardous metals like arsenic and mercury from electronic waste harm both the environment and human health. Recycling processes remain underdeveloped, requiring new eco-friendly solutions. This paper reports on the synthesis and properties of the cationic surfactants ammonium terthiophene (CTT) and 3,4-propylene-dioxythiophene (C-ProDOT), which may have potential use in organic electronics. Ecotoxicological tests showed no significant long-term toxicity and medium-to-high biodegradability, which are keys for environmental protection. These surfactants also displayed selective bacterial adhesion, making them candidates for bionic devices. Life cycle assessment revealed higher energy use and ecotoxicity for C-ProDOT than CTT, underscoring the need for sustainable chemical design.ennon-pathogenic bacteria adhesionoptoelectronic surfactantsamphiphilic optoelectronic moleculesoligothiophenesProDOTorganic materials for sensors and devicesjournal-article10.3390/ma18184349
