Schiff base Organic Frameworks (SOFs) based chemosensor have been synthesized and utilized for recognization of biologically relevant fluoride anion. The chemosensor is selective for fluoride (F−) and exhibits reversible UV–Vis response with alternate addition of aluminum (Al3+). Interestingly a fluorescence ‘turn on’ response has been noticed with concomitant addition of fluoride. TICT, PTTS and restricted Cdouble bond; length as m-dashN isomerization has been taken into account in order to explain the florescence ‘turn on’ phenomenon. Significantly, the limit of fluoride detection is nano molar level (∼10 nM). The reversible UV–Vis phenomena have been used for designing AND–NAND–NOT–NOR–OR–XOR–XNOR based complex logic circuit to prepare potential feedstock as ‘Lab-on a-Molecule’.
