Finally, we set out to apply the multi-stimuli and NIR responsiveness of PAT 1 in advanced molecular logic operations. To this end we used light and pH changes as input stimuli and the absorption intensity at different wavelengths as corresponding outputs (see Figure and the Supporting Information for the complete overview). With this setup we were able to generate a variety of binary logic gates such as AND, SAND, IDENTIY, and NOT gates. Further, also sequential logic operations could be realized in the form of three-or four-input keypad locks.
