From amber to red : The water‐soluble polythiophene derivative 1 forms a supramolecular complex with ATP (adenosine triphosphate) through electrostatic and hydrophobic cooperative interactions which results in a color change of the aqueous solution from yellow to pink‐red (see photo; AMP/ADP=adenosine mono‐/diphosphate). Besides naked‐eye detection of ATP, the detection limit may be extended to 10 −8 M by using fluorometry.
