An expanded triptycene (hexaphenylbenzene based triptycene) monomer was synthesized from triiodotriptycene. Using this monomer, two kinds of organic microporous polymers HTPs (HTP-A and HTP-B) were prepared by Friedel–Crafts and Scholl reactions. Their structure and properties were characterized by FT-IR, solid 13C NMR, powder XRD, SEM, TEM and gas absorption. Nitrogen sorption analysis displayed...
Kinetics and its regulation by extrinsic physical factors govern selectin–ligand interactions that mediate tethering and rolling of circulating cells on the vessel wall under hemodynamic forces. While the force regulation of off-rate for dissociation of selectin–ligand bonds has been extensively studied, much less is known about how transport impacts the on-rate for association of these bonds and...
