Abstract: A series of new tricyclic heterocyclic xanthene-1,8-diones tethered with chromophoric dibenzo [b, d]furan, dibenzo[b, d]thiophene and 9-methyl-9H-carbazoles were synthesized through one-pot condensation of dibenzo[b, d]furan-2-carbaldehyde, dibenzo[b, d] thiophene-2-carbaldehyde and 9-methyl-9H-carbazole-3-carbaldehyde with cyclic 1,3-dicarbonyls in the presence of recyclable PPA-SiO2 catalyst under solvent-free conditions. Further, UV-Visible absorption properties of all the synthesized compounds were investigated in CHCl3, THF and acetonitrile.
