Diarylethenes with long π-conjugated heteroaryl groups were synthesized and their absorption spectra, photocyclization and cycloreversion quantum yields, and thermal stability were examined. The diarylethene with isopropyl groups at the reactive carbons was found to have a low decoloration quantum yield and thermal reversibility at high temperature above 100°C.
