Maleimidophenyl isocyanates as postpolymerization modification agents and their applications in the synthesis of block copolymers

The maleimide structure is highly reactive, exemplified by thiol–ene click reactions with thiols and Diels–Alder reactions with furans. Although postpolymerization modifications and macromolecular conjugations involving maleimide units have been widely studied, mostly due to their selectivity and high reactivity, little has been reported on the one-pot postpolymerization introduction of maleimides in polymer chains. Herein, we report p-maleimidophenyl isocyanate and its derivatives as modification agents to introduce maleimide moieties by reaction with hydroxy groups into polymer chains. The high reactivity of the resulting modification agents and of the corresponding maleimide structures once inserted in the polymer chains was examined by studying their reaction kinetics. Furthermore, these modification agents were successfully applied to the synthesis of macromonomers for graft polymerization and various block copolymers, with, for example, AB-type, star-shaped, and H-shaped architectures.

Convergent preparation and photophysical characterization of dimaleimide dansyl fluorogens: Elucidation of the maleimide fluorescence quenching mechanism

Dimaleimide fluorogens are being developed for application to fluorescent protein labeling. In this method, fluorophores bearing two maleimide quenching groups do not fluoresce until both maleimide groups have undergone thiol addition reactions with the C

Design and synthesis of trifunctional perfluorophenyl azide-based photoactivatable reagents

The novel trifunctional perfluorophenyl azide based photoactive compounds 3, 6 (unstable), 10 and 13 are described. Diels-Alder reaction of maleimide 13 with diene-heteropolytungstate 14 produced the PFPA-HPT-maleimide trifunctional conjugate 15.
