A fluorescent probe, Cy-ArB, is developed for real-time monitoring of H2O2 fluctuations in cells and in vivo during ischemia/reperfusion processes.

Color photoresists are the key materials for the fabrication of color filters (CFs). Organic dyes offer a promising alternative to the conventional pigment-based system to make CFs with higher resolution. However, the stability of dye molecules is an urgent problem to be solved. Herein, we designed and synthesized a series of highly stable zinc phthalocyanine dyes containing polymerizable acrylamide groups. Upon light exposure, dense and insoluble network structures were formed in the prepared color filters, which increase the thermal stability and anti-migration capacity of these dyes.
