摘要：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 colour change and fluorescence-changing, altering phase states could also tune their colours via different temperature, which is rare performance for diarylethene derivatives. Especially, the photocylization ratio is as high as 100% for compound 20 bearing two phenolphthalein groups. These versatile properties are helpful to the design of pH sensitive photoswitches, fluorescent sensors, and molecular logical gates. (C) 2016 Elsevier Ltd. All rights reserved.
