3-Urea-1,8-naphthalimides are good chemosensors: a highly selective dual colorimetric and fluorescent ICT based anion sensor for fluoride
DUKE, REBECCA MONICA; GUNNLAUGSSON, THORFINNUR (2011)he 1,8-naphthalimide sensor 1 was developed as a colorimetric and fluorescent sensor for anions. Being the first example of such anion sensors, where the 3-position of the naphthalimide ring is used to incorporate the anion ... -
Colorimetric sensing of anions in aqueous solution using a charge neutral, cleft-like, amidothiourea receptor: Tilting the balance between hydrogen bonding and deprotonation in anion recognition
GUNNLAUGSSON, THORFINNUR; DUKE, REBECCA MONICA; O'BRIEN, JOHN; MCCABE, THOMAS (2008)The design, synthesis and physical evaluation of 1, a visible colorimetric `naked eye? pyridyl based bis-amidothiourea sensor for anions, is described. This charge neutral sensor gives rise to significant changes in the ... -
Fluorescent sensing of anions using a bis-quinoxaline amidothiourea based supramolecular cleft; an example of an anion induced deprotonation event
DUKE, REBECCA MONICA; GUNNLAUGSSON, THORFINNUR (2010)The quinoxaline 1, possessing a 2,6-pyridyl-based amidothiourea moiety, with the view of forming a pre-organised molecular cleft, was developed as a fluorescent anion sensor. The sensing ability of 1 was evaluated in organic ...
