ABSTRACT
Boron nitride nanosheets (BNNSs) with micron-sized edges were prepared in high yields by direct exfoliation of bulk hexagonal boron nitrides using ionic liquids (ILs). The ILs strongly attached onto BNNS surfaces, and dramatically enhanced the exfoliation, giving highly concentrated BNNS dispersions (â¼1.9 mg mL(-1)) and yields reaching â¼50%.
ABSTRACT
A new 2-D coordination network with 22.2-A square-grid coordination networks was prepared from a dicopper(II) tetraacetate [Cu2(AcO)4] as a linear linker motif and 5,10,15,20-tetra-4-pyridyl-21H,23H-porphine (H2TPyP) as a four-connected vertex, forming a regular high-porous structure. The characterization by N2 adsorption indicated that this coordination network has uniform micropores and gas adsorption cavities.
