A　new　triphenylethylene-modified　indolo[2,3-b]quinoxaline　TPE-IQ　has　been　synthesized　by　a　mild　Suzuki-Miyaura　coupling　reaction.　The　thermal,　electrochemical,　photophysical,　aggregation,　and　acidofluorochromic　and　mechanofluorochromic　properties　were　investigated.　TPE-IQ　shows　typical　solvatochromism　and　aggregation-induced　emission　enhancement　features.　TPE-IQ　also　exhibits　interesting　reversible　acid　and　mechanical　force-responsive　properties.　This　work　highlights　the　development　of　multi-stimuli　responsive　organic　material　containing　indolo[2,3-b]quinoxaline　moiety.
