Gels prepared from π-conjugated low-molecular-mass organogelators (LMOGs) have shown that the properties can be tailored and functionalized by incorporating stimuli-responsive units, for example, temperature-sensitive and photoactive units, as a part of the gelator molecule. These stimuliresponsive organogels,[1–3] alternatively called “smart” or “intelligent” gels, show reversible changes in morphology and/or physical properties in response to various external stimuli.[3–9] In particular, photoactive smart gels comprising π-conjugated LMOGs have been actively explored for various applications.[10–17] With the aim of developing fluorescent optical memory devices or logic gates containing LMOGs, efficient fluorescence-switching organogel systems activated by a single external stimulus have already been demonstrated.[12, 18] However, no reliable multistimulus logicgate switching has been achieved so far …
