Zwitterionic Poly(amino acid methacrylate) Brushes
A new cysteine-based methacrylic monomer (CysMA) was conveniently synthesized via selective thia-Michael addition of a commercially available methacrylate-acrylate precursor in aqueous solution without recourse to protecting group chemistry. Poly(cysteine methacrylate) (PCysMA) brushes were grown from the surface of silicon wafers by atom-transfer radical polymerization. Brush thicknesses of ca...
متن کاملZwitterionic 1-{(E)-[(2-methylphenyl)iminiumyl]methyl}naphthalen-2-olate
The title Schiff base, C18H15NO, crystallizes in its zwitterionic form and an N-H⋯O hydrogen bond closes an S(6) ring. The dihedral angle between the aromatic ring systems is 36.91 (10)°. Weak aromatic π-π stacking occurs in the crystal [minimum centroid-centroid separation = 3.7771 (15) Å].
متن کامل2-Azaniumyl-4-(ethylcarbamoyl)butanoate: the zwitterionic form of the amino acid theanine
In the title zwitterion, C(7)H(14)N(2)O(3), the ethyl-amino and the 5-oxo groups are positionally disordered with occupancy ratios of 0.50:0.50 and 0.70:0.30, respectively. The terminal ethyl -CH(3) group undergoes considerable thermal motion. In the crystal, mol-ecules are linked via N-H⋯O hydrogen bonds, forming a two-dimensional arrangement propagating in the bc plane.
متن کامل8-Ammonionaphthalene-2-sulfonate monohydrate: the zwitterionic hydrate of 1,7-Cleve’s acid
The structure of 8-amino-2-naphthalene-sulfonic acid monohydrate (1,7-Cleve's acid hydrate), C(10)H(9)NO(3)S·H(2)O, shows the presence of a sulfonate-aminium group zwitterion, both groups and the water mol-ecule of solvation giving cyclic R(3) (3)(8) O-H⋯O and N-H⋯O inter-molecular hydrogen-bonding inter-actions, forming chains which extend down the a axis of the unit cell. Additional periphera...
متن کاملZwitterionic (E)-1-[(4-nitrophenyl)iminiomethyl]naphthalen-2-olate
The title compound, C(17)H(12)N(2)O(3), was synthesized by the reaction of 2-hy-droxy-1-naphthaldehyde with 4-nitro-benzenamine. These condense to form the Schiff base, which crystallizes in the zwitterionic form. In the structure, the keto-amino tautomer has a fairly short intra-molecular N-H⋯O hydrogen bond between the 2-naphthalenone and amino groups, with electron delocalization. The mol-ec...
