photochromic
device with 1o and 1c states, was developed
and characterized. In this device, the DTE unit can reversibly switch
the SubPz absorbance from green to near-infrared [λmax (o/c) = 527 nm/740 nm], as well as the SubPz fluorescence and singlet
oxygen quantum yields. The core of this design involves using a highly
tunable SubPz chromophore that shares its quasi-isolated ethene moiety
with a DTE photoswitch.
