Description:
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.
