摘要: Frechet-type benzyl ether dendrons of second and third genera- tions with a carboxyl group (G2,G3) at the apex site could attach to poly(4- vinylpyridine) (PVP),forming hydro- gen-bonded dendronized polymers (HB denpols) in their common solvent, chloroform. The HB denpols show unique self-assembly behavior,forming vesicles solvent under ultrasonic treatment. structure morphology were char- acterized by dynamic light scattering (DLS),static (SLS), SEM,TEM,and AFM. size decreases thickness vascular membrane increases as molar ratio Gx/PVP increases. hydrogen bonding, p-p aromatic stack- ing dendrons,and considera- ble difference architecture between dendron Gx PVP are main factors facilitating assembly solvent.
