dynamic, biological environments. Here, two derivatives from thymine (T), that is N‐[2‐(3,4‐Dihydro‐5‐methyl‐2,4‐dioxo‐1(2H)‐pyrimidinyl)acetyl]‐L‐phenylalanine (T‐phe) and N‐(2‐Aminoethyl)‐3,4‐dihydro‐5‐methyl‐2,4‐dioxo‐1(2H)‐pyrimidineacetamide (T‐NH2) were synthesized. Then the optimal condition for self‐assembly of T‐phe and T‐NH2 driven by melamine (M) was explored. It was observed that M/T kept

having at least one amino group attached to an aliphatic chain, has been synthesized from (1-thyminyl)thioacetamide in good isolated yields (69–86%). N-[2-(4-Imidazolyl)ethyl](1-thyminyl)thioacetamide was hydrolyzed to its amide on prolonged heating in water. Ammonium sulfide (20–22% solution in water) has found interesting new applications in the efficient synthesis of N-[2-(3-indolyl)ethyl](1-thyminyl)thioacetamide
Based on a T-Hg2+-T binding mode, a sensitive ratiometric fluorescent chemosensor for aqueous Hg2+ was developed with a heptamethine cyanine chromophore containing a thymine moiety.
