Jin, Piaopiao published the artcileMulti-responsive diarylethene-phenolphthalein hybrids by multiple stimuli, COA of Formula: C15H14Cl2S2, the publication is Tetrahedron (2016), 72(35), 5488-5494, database is CAplus.
Photochromic diarylethene derivatives cherishing phenolphthalein moieties were designed and constructed. We present efforts to investigate their versatile performances in multi-responsive properties with multiple stimuli of light, acid/base and temperature/heat. Results show their fluorescence could be on-off switched not only by different lights but also by acid/base. Besides lights and acid/base controllable color change and fluorescence-changing, altering phase states could also tune their colors via different temperature, which is rare performance for diarylethene derivatives Especially, the photocyclization ratio is as high as 100% for compound 2o bearing two phenolphthalein groups. These versatile properties are helpful to the design of pH sensitive photoswitches, fluorescent sensors, and mol. logical gates.
