Fifteen title compounds, e.g. (I)-(III), are prepared essentially as described previously. Evaluation of their absorption, emission and laser properties shows that N-allyl substituted derivatives (Ia) and (IIa) have high fluorescence quantum yields and laser efficiencies of 137 and 140%, respectivel

Abstract
Several long‐chain alkyl‐D‐glucofuranosidurono‐6,3‐lactones were synthesized by the acid‐catalysed glycosidation of glucurono‐6,3‐lactone. The alkyl β‐D‐glucofuranosidurono‐6,3‐lactones were reacted with sodium borohydride to give the corresponding alkyl β‐D‐glucofuranosides, and with 2‐aminoethanol and N,N‐dimethylethanediamine to give the corresponding alkyl‐N‐(2‐hydroxyethyl)‐β‐D‐glucofuranosiduronamides and alkyl‐N‐[2‐(dimethylamino)ethyl]‐β‐D‐glucofuranosiduronamides, respectively. The dodecyl‐N‐[2‐(dimethylamino)ethyl]‐β‐D‐glucofuranosiduronamides were quaternized with iodomethane to give the ammonium iodides. These new compounds, and some representative derivatives, were characterised by ^1^H‐ and ^13^C‐NMR spectroscopy. The physical properties (liquid‐crystal behaviour, surface tension, CMC) of some of these compounds were also determined.
