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
