The design algorithm of fully photonic two-address molecular logic gates (MLGs) based on the supramolecular bis-styrylquinoline S3S dyad was considered in which two pieces of 2-(4-oxystyryl)quinoline are linked to each other with a trimethylene “bridge.” The reaction of the photoisomerization of styrylquinoline fragments is used to switch between the states, and the reading of the output signal is done by the absorption and luminescence of these fragments. In the latter case, both input and output signals for MLGs are photons; i.e., homogeneity of input and output signals is achieved, which is necessary for the construction of more complex circuits from these gates. It is shown that the S3S dyad simulates the action of logic gates “AND,” “OR,” “NOT-AND” (“NAND”), “NOT-OR” (“NOR”), “IMPLICATION” (“IMP”), and “INHIBIT” (“INH”).
