The first maximum emission wavelength beyond 1200 nm acceptor-substituted squaraine fluorophore with ultra-high brightness and photostability has been developed. It can be co-assembled with bovine serum albumin to form an...

NP-TPA-Tars exhibits bright emission in various states with large Stokes and facile targeted modifications, and has improved imaging efficacy, better photostability than their commercial counterparts in imaging of targeted subcellular structures.

Piezochromic fluorescent (PCF) materials that feature high sensitivity and wide-range switching are attractive in intelligent optoelectronic applications but remain a significant challenge in their fabrication. Here we present a propeller-like...
