Abstract
1,8-Di(quinol-2-yl)octa-1,7-diyne and 1,8-di(phenanthren-9-yl)octa-1,7-diyne were synthesised by conventional and microwave-assisted methods in good yields. Microwave irradiation enhances the rate of these reactions. Photophysical properties of these derivatives were also evaluated, and it was found that 1,8-di(phenanthren-9-yl)octa-1,7-diyne displays a higher fluorescence quantum yield than 1,8-di(quinol-2-yl)octa-1,7-diyne. The molecular structures of 1,8-di(quinol-2-yl)octa-1,7-diyne and 1,8-di(phenanthren-9-yl)octa-1,7-diyne were established by single-crystal X-ray diffraction studies.
