[2 + 2 + 2] cyclotrimerisation as a convenient route to 6N-doped nanographenes: A synthetic introduction to hexaazasuperbenzenes
DRAPER, SYLVIA; Wijesinghe, Lankani P.; Perera, Sarath D.; Larkin, Eugene; Ó Máille, Gearóid M.; Conway-Kenny, Robert; Lankage, Buddhie S.; Wang, Longsheng (2017)6N-containing polyphenylene precursors were generated via [2 + 2 + 2] cyclotrimerisation. On methoxy substitution complete ring-closure can be achieved (via FeCl3-mediated oxidative cyclodehydrogenation) to give asymmetric ... -
A dinuclear extension to constrained heteroleptic Cu(I) systems
DRAPER, SYLVIA (2011)This article reports the synthesis and optical properties of three dinuclear, cationic copper complexes [Cu2(?-dppm)2(?-L)](NO3)2 (dppm diphenyldiphosphinomethane, L: LA 3,6-bis(2-pyridyl)-4,5-diphenyl-pyridazine, LB ... -
Methoxy functionalisation: exerting synthetic control of the supramolecular and electronic structure of nitrogen-doped nanographenes
DRAPER, SYLVIA (2014)We describe a series of functionalized N-containing heterosuperbenzenes, created with a view to investigating the strategic role of methoxy substituents in (i) promoting cyclodehydrogenation and (ii) tuning the electronic ... -
'Robust Self-Assembled Monolayers of Ru(II) and Os(II) Polypyridines on Gold Surfaces: Exploring New Potentials'
MURPHY, FRANCES; DRAPER, SYLVIA (2009)Metal complexes [M(phtpy)(pztpy)](PF6)2 (phtpy = 4'-phenyl-2,2':6',2"-terpyridine, pztpy = 4'-(Npiperazinyl)- 2,2':6',2"-terpyridine, M = Ru, Os) were prepared and examined spectroscopically and electrochemically. The ... -
A structurally versatile coordination polymer: demonstrating spontaneous resolution, conformational polymorphism and gel formation
DRAPER, SYLVIA (2013)Conformationally flexible C2-symmetric 2-(2?-cyanophenoxy) benzonitrile (O,O-CPBN) was self-assembled using silver ions into spontaneously resolved, helical and coordination polymer gel structures including unprecedented ... -
Substituted Pyridazines As Ligands In Homoleptic (fac and mer) and Heteroleptic Ru(II) Complexes
DRAPER, SYLVIA (2011)This article reports the preparation of a range of phenyl, pyridyl and pyrazinyl substituted pyridazinesvia the inverse electron demand [2 + 4] Diels?Alder reaction between 3,6-di(2-pyridyl)-1,2,4,5-tetrazines (bptz) and ... -
Synthesis and 13C NMR assignment of ammonium benzylidenepropanedioates and benzylidenepropanediamides
DRAPER, SYLVIA (1998)Mono- and di-ammonium benzylidenepropanedioates are synthesised, the molecular structure of a mono-ammonium salt confirmed by X-ray diffraction, and the 13C NMR spectra of the salts and the related benzylidenepropanediamides ... -
The synthesis and characterisation of novel ferrocenyl polyphenylenes
WATSON, GRAEME; DRAPER, SYLVIA (2012)This work describes the synthesis and characterisation of a new series of polyphenylenes with up to four ferrocenyl moieties. The synthetic route involves the preparation of a number of novel precursors. Cyclopentadienones, ... -
Synthesis, characterisation and biological evaluation of N-(ferrocenyl)naphthoyl amino acid esters as anticancer agents
DRAPER, SYLVIA (2010)A series of N-(ferrocenyl)naphthoyl amino acid esters 5?18 has been prepared by coupling ferrocenyl naphthoic acids 3?4 to ?-amino acids and linear amino acids in the presence of N-(3-dimethylaminopropyl)-N?-ethylcarbodiimide ... -
Visible light-harvesting trans bis(alkylphosphine) platinum(II)-alkynyl complexes showing long-lived triplet excited states as triplet photosensitizers for triplet-triplet annihilation upconversion
DRAPER, SYLVIA (2013)Symmetric and asymmetric linear trans-bis(tributylphosphine) Pt(II) bis(acetylide) complexes with functionalized aryl alkynyl ligands (coumarin, naphthalimide and phenyl acetylides) were prepared, which show enhanced ...
