This study reports the synthesis and photophysical characterization of 12 compounds from two new fluorophore architectures, in order to study the photophysics of cruciforms in relation to stilbenes. Therefore, analogues of cruciforms missing a styryl or arylethynyl branch were synthesized. The response of some of these T-shaped fluorophores to metal salts and protons in CH2Cl2 was studied. Likewise, the solvatochromicity of all derivatives was studied. The derivatives lacking a distyrylbenzene moiety were found to be photochemically unstable and possessed characteristics similar to stilbenes. Derivatives containing a distyryl branch were found to be photochemically stable, with responses analogous to cruciforms.
