10.0 Hz), and 2.0 (d, 1 H, J = 8.0 Hz).Recrystallization from ether-hexane gave 11 as yellow crystals, mp 144-145°.

A Cell‐Targeted Non‐Cytotoxic Fluorescent Nanogel Thermometer Created with an Imidazolium‐Containing Cationic Radical Initiator

“…Generally, natural and artificial cationic structures (including positively ionizable amino groups) are known to support the ability of nanoparticles to enter live cells . Nevertheless, this concept cannot be easily applied to fluorescent nanogel thermometers because no cationic radical initiators are available yet . Herein, we developed a newly designed cationic radical initiator, 2,2′‐azobis‐[2‐(1,3‐dimethyl‐4,5‐dihydro‐1 H ‐imidazol‐3‐ium‐2‐yl)]propane triflate (ADIP, Figure a), and synthesized a cationic fluorescent nanogel thermometer ( 1 ; Figure a) with this first cationic radical initiator.…”

Cationic Polymer Nanoparticles and Nanogels: From Synthesis to Biotechnological Applications

“…On the other hand, cationic initiators containing quaternized nitrogens, such as N , N ′-dimethyl-4,4′-azobis­(4-cyano-1-methylpiperidine) dinitrate (DACMP), have been used as an alternative to cationic bisamidines …”
