Abstract
Conjugated polyarenes have been the focus of considerable interest due to their
potential for serving as materials for electroluminescence devices, since they possess
high fluorescence efficiency and are technically processable. A novel Family of
phenanthroline-based compounds were synthesised via a [2+4] Diels-Alder
cycloaddition reaction between specifically designed cyclopentadienone based
synthons that incorporate the already fused phenanthroline moiety 11b-Hydroxy-1,3-
diphenyl-1,11b-dihydro-7,8-diaza-cyclophenta[l]phenanthrene-2-one (1a) and 11b-
Hy d r o x y - 1 , 3 - d i ( 4 - t e r t - b u t y l p h e n y l ) - 1 , 1 1 b - d i h y d r o - 7 , 8 - d i a z a -
cyclophenta[l]phenanthrene-2-one (1b) and various di-substituted acetylenes. These
systems have been found to display tuneable fluorescent capabilities, which make them
promising material for application in optoelectronics as well showing excellent metal
coordination potential
