DIBMA 6 Fluorescein

The new DIBMA 6 is not only smaller than its predecessors (DIBMA 10 and DIBMA 12) but together with Sulfo-DIBMA belongs to a new generation of DIBMA’s which are RAFT polymerized. This achieves a reduction in both monomer size and lower polydispersity, meaning that if you need your copolymers to all have a similar size this is the copolymer to choose.

This first-of-its-kind, functionalized version of classic DIBMA 6 is fluorescently labeled with fluorescein. This means a pH-dependent fluorescent excitation at ~485 nm and emission maximum at ~510 nm.
