Abstract
A new tetrathiafulvalene-anthracene dyad 1 with two “tetraethylene glycol” units was synthesized and characterized. Strong chemiluminescence was observed upon reaction of dyad 1 with singlet oxygen ( 1O 2), and this reaction shows fairly good selectivity toward 1O 2 over other reactive oxygen species. Due to the introduction of two hydrophilic “tetraethylene glycol” units, the detection of 1O 2 with dyad 1 can be performed in alcohol/water solution, which is relatively a mild medium when compared with water/tetrahydrofuran solution required by other tetrathiafulvalene-anthracene dyads. Dyad 1 may have a wider use for detection of 1O 2 in biological systems.
