بخشی از متن:
Photochemical control of molecules has provided chemists with the ability to establish high spatiotemporal
control of chemical configuration and activity. Herein, we report UVC‐454, UVA‐454, and Spiro‐CL as photoactivatable
chemiluminescence compounds. UVC‐454 and UVA‐454 are protected with ortho‐nitrobenzyl
protecting groups that provide irreversible photochemical uncaging of the chemiluminophore species through
UV light irradiation. UVC‐454 and UVA‐454 can be selectively activated based on uncaging wavelength, and
demonstrate ability to be photoactivated in water. Spiro‐CL is a novel chemiluminescent spiropyran that can
reversibly interconvert from its stable spiropyran form to a metastable merocyanine form through UV or visible
light irradiation, respectively. Further, this compound exhibits chemiluminescence in its open form upon irradiation
with UV light in DMSO
