Fabrication of nitrogen-doped hollow carbon nanospheres with variable nitrogen contents using mixed polymer brushes as precursors

Design and synthesis of heteroatoms-doped porous carbon model materials with controllable nitrogen contents and similar pore structure are of great importance for fundamental understanding of the correlation between their intrinsic properties and applications. Herein, we report a synthetic strategy for synthesis of nitrogen-doped hollow carbon nanospheres with variable nitrogen contents, similar pore structure and morphology by pyrolysis of mixed polymer brushes formed through surface-initiated atom transfer radical polymerization of monomer mixtures of styrene and 4-vinylpyridine. With increasing 4-vinylpyridine fractions in the monomer mixture, nitrogen contents in the final carbon products increase up to about 5.5 wt%. As example applications, electrocatalytic performance for oxygen reduction reactions in both basic and acidic media and carbon dioxide adsorption properties of the thus-formed materials are investigated to evaluate the synthetic approach. The results reveal that the higher nitrogen contents doped in carbon do not guarantee the better performance for either electrocatalysis or carbon dioxide adsorption. It is the fraction of pyridinic nitrogen that dominates the electrocatalytic activity and carbon dioxide adsorption capacity. The findings demonstrate that mixed polymer brushes are promising precursors for the formation of heteroatoms-doped carbon materials, particularly as model materials for fundamental understanding their structure?properties correlations.

Synthesis of New Diketopiperazines, Thiolation to Thiodiketopiperazines, and Examination of Their ROS-Generating Properties

A variety of new symmetrical and unsymmetrical diketopiperazines have been prepared from free amino acids by using a previously developed microwave-assisted protocol. This included the successful incorporation of L-pyroglutamic acid as an unusual building block. The diketopiperazines were then thiolated electrophilically to the corresponding bis(methylthio)- and epidithiodiketopiperazines. Initial experiments showed a promising activity towards the generation of reactive oxygen species in HeLa cells. A variety of novel symmetrical and unsymmetrical thiodiketopiperazines have been prepared by methyl dichlorophosphite assisted dimerization of free amino acids and by thiolation of the resulting cyclic dipeptides with elemental sulfur and NaHMDS. Some of the sulfur compounds showed interesting activity in the generation of reactive oxygen species in HeLa cells.
