Azo molecules, characterized by the presence of a -N=N- double bond, are widely used in various fields due to their sensitivity to external stimuli, ch as light. The emergence of bacterial resistance has pushed research towards designing new antimicrobial molecules that are more efficient than those currently in use. Many authors have attempted to exploit the antimicrobial activity of azobenzene and to utilize their photoisomerization for selective control of the bioactivities of antimicrobial molecules, which is necessary for antibacterial therapy. This review will provide a systematic and consequential approach to coupling azobenzene moiety with active antimicrobial molecules and drugs, including small and large organic molecules, such as peptides. A selection of significant cutting-edge articles collected in recent years has been discussed, based on the structural pattern and antimicrobial performance, focusing especially on the photoactivity of azobenzene and the design of smart materials as the most targeted and desirable application.

“…The preparation of ionic liquids was initiated by Walden in 1914 with the synthesis of ethyl ammonium nitrate, [EtNH 3 ][ NO 3 ] by a reaction between concentrated nitric acid and ethylamine [25]. After a long gap, in between the 70s and 80s, the alkylimidazolium halogenoaluminate ionic liquids, termed "first-generation ionic liquids" were developed via reaction between aluminum halides and imidazolium halides [26].…”

“…A global action plan has therefore been formulated by the World Health Organization (WHO) about antimicrobial resistance with a list of antibiotic-resistant priority pathogens [2]. More responsible use of antibiotics is recommended along with the development of effective and new drug treatments, which is not an economically suitable alternative to pharmaceutical companies due to the time and expenses involved [3]. Although it is practically unavoidable to completely stop the appearance of resistance towards the new drugs considering the fact that antibiotics might not be the only cause for the surge in resistance.…”

“…Azoaromatic compounds are significant core motifs and found the prevalence in a variety of applications due to their unique properties of the azo unit ( Pang et al, 2020 ). They are universally applied in synthetic chemistry ( Nguyen et al, 2018 ), sensing probes ( Dong et al, 2015 ), organic dyes ( Bafana et al, 2011 ), smart materials ( Mohamed et al, 2015 ; Gerkman et al, 2020 ), and therapeutic agents ( Lizard et al, 2020 ; Babamale et al, 2021 ). Considering the widespread utility of aromatic azo scaffolds, a handful of methods for their formation were established by adding an external oxidant or noble metal catalyst ( Grirrane et al, 2008 ; Dai et al, 2018 ; Han et al, 2021 ; Sitter and Vannucci, 2021 ).…”
