Electroactive Poly(amino acids). Part 1 .Modified Electrodes from Platinum with an Adsorbed FiIm of Poly(N E-4-nitrobenzoyl- L- lysnie )

Abeysekera, Ajit M.; Vipond, David; Perera, Sarath D.; Grimshaw, James (1989)

Poly(Ne-4-nitrobenzoyl-L-lysine)is obtained with average molecular weight (2.0 + 1.3) x 10 5 by reaction between the monomer N-carboxyanhydride and sodium hydride. Platinum has been dipcoated with this material from ...
Electroactive Poly(amino acids). Part 2.Copolymers of Ne-4-Nitrobenzoyl- L-lysine with Inactive Amino Acids: Modified Electrodes with these Polymers and Poly( pyrrole) and with Poly(1- [2-(4-nitrobenzoyl)aminoethyl]pyrrole}

Grimshaw, James; Perera, Sarath D. (1989)

Co-polymerization of the N-carboxyanhydrides derived from NE-4-nitrobenzoyl-L-lysine(NBL) and one of the amino acids, NE-4b- enzoyl-L-lysine, L-leucine, and glycine afforded electroactive materials. These can be adsorbed ...
Thesis Summary - KSDP-1989

Perera, Sarath D. (1989)
Redox behavior of a polypyrrole modified electrode where the pyrrole has N-substituted 9-cyanoanthracene groups

Perera, Sarath D.; Grimshaw, J. (J. Electroanal. Chem., 1989)
Poly( pyrrole-pyromellitimide) modified electrodes

Grimshaw, James; Perera, Sarath D. (1990)

Poly(pyrrole-pyromellitimide) films were prepared by the anodic oxidation of N,N’-bis[2-(lpyrrolyl)ethyl]pyromellitimide (BEP) in acetonitrile media. These films showed a stable redox behavior in acetonitrile as well as ...
Electroactive Poly(amino acids). Part 3.Ferrocene-doped Poly( L-lysine) as an Electroactive Layer on Platinum

Abeysekera, Ajit M.; Grimshaw, James; Perera, Sarath D. (1990)

Poly(L-lysine) hydrobromide in water was coated onto a platinum electrode and then doped with ferrocene residues by reaction with ferrocenecarbonyl chloride in benzene containing pyridine. The behaviour of this coating to ...
Redox behaviour of polypyrrole films containing naphthoquinone and benzoquinone groups

Grimshaw, James; Perera, Sarath D. (1990)

The synthesis and electropolymerization of 2-[2-(l-pyrrolyl)ethylamino]-3-chloronaphthoquinone (PNQ) and 2,5-bis[2-(1-pyrrolyl)ethylamino]-2,6-dichlorobenzoquinone (PBQ). are described. Electrochemical behaviour of poly(PNQ) ...
Electrochemical behaviour of poly( thiophene-benzoquinone) films

Grimshaw, James; Perera, Sarath D. (1990)

Poly(thiophene-benzoquinone) films were prepared on platinum spheres by electropolymerization of the monomer 1-[3-(3-thienyl)propyl]2,4,5-trichloro-3,6 –dioxo-1,4-cyclohexadiene-l-acetate (TBQ) in acetonitrile. These films ...
An alternative institutioanal strategy for slum improvements: some lessons from urban TCCS in colombo

Vidanapathirana, Upali (1991)
Poly(pyrro1e) as a Support for Electrocatalytic Materials

Curran, Domonic; Grimshaw, James; Perera, Sarath D. (1991)

Pyrrole undergoes oxidative polymerization from acetonitrile solution at a metallic anode to form a dark coloured skin that adheres firmly to the metal surface. This simple electropolymerization step, when applied to pyrrole ...
Complexes including acetylides formed from 3-diphenylphosphinocamphor and platinum or palladium

Perera, Sarath D.; Shaw, Bernard L. (1991)

Treatment of lithiated D-camphor with a half molar equivalent of PPh2Cl gives the 3-diphenylphosphino enolate anion [PPh2(C10H14O)]- as the only phoshorus-containing species. Treatment of lithiated D-camphor with one ...
3- Diphenylphosphino-(I R)-( +)=camphor Dimethyl hydrazone and its Complexes with Group 6 Metal Carbonyls: Crystal Structures of the Hydrazone and [Mo(CO)4(PPh2C10H15NNMe2)]

Perera, Sarath D.; Shaw, Bernard L.; Thornton-Pett, Mark (1991)

Prolonged treatment of (1R)-(+)-camphor with 1,l -dimethylhydrazine gives (1R)-( +)-camphor dimethylhydrazone 3a which with LiBu, followed by PPh,CI, gives the corresponding compound 3c which has the Ph2P group in 3-exo ...
Chemistry of molybdenum complexes derived from exo-3-diphenylphosphino-(1R)-(+)-camphor dimethylhydrazone.

Perera, Sarath D.; Shaw, Bernard L. (1991)
