Macro-organic molecules (1,2-BFBTPB and 1,2-BHPTPB), composing of benzene frame substituted by tetraphenyl and bisphenyl containing functional groups, were synthesized, and their structural and photophysical properties were investigated. X-ray structure showed that the compounds had panwheel-type geometries. The photophysical properties of 1,2-BFBTPB and 1,2-BHPTPB were investigated in terms of excitation, luminescence, UV and reflectance. When exposed to UV light, the compounds produced deep blue to green luminescence, depending on the solvent. It was found that the proton transfer from the organic molecule to the solvent played a key role in the observed solvatochromism. Quantum mechanical calculations for 1,2-BFBTPB and 1,2-BHPTPB were also performed to interpret the observed photophysical properties.
