A highly efficient method was successfully developed for the synthesis of benzo[h]quinoline analogues. Compounds obtained directly from each synthesis were more than 90% pure and did not require any further purification. On the basis of the fluorescence spectra of the compounds in the initial library, fifteen benzo[h]quinoline analogues were designed. Four of these analogues showed very favorable absorbance and fluorescence profiles and have the potential to be used as organic antennas for luminescence resonance energy transfer (LRET) studies.
