In this thesis, the photophysical behavior of stilbene derivatives and pentiptycene containing gold(I) complexes are investigated. In Chapter 1, we introduce some background, including basic photochemistry, photochemistry of stilbene derivatives, properties of gold(I) complexes, and features of the pentiptycene scaffold. In Chapter 2, we explore the application of the meta-amino effect in stiff-stilbene, and investigates the interplay between the rigidity and planarity of stiff-stilbene and the meta-amino effect on the fluorescence quantum efficiency. In Chapter 3, we investigate whether the meta-amino substitution could induce the formation of a twisted intramolecular charge transfer (TICT) state for stilbenes containing a strong electron-withdrawing group. Model compounds of constrained single bonds are synthesized to identify the single bond that is responsible for the TICT state. In Chapter 4, the correlation between the polymorph of a pentiptycene-containing gold(I) isocyanide complex [Ph-Au-C≡N-Phip-OC8H17] and the observed photophysical behavior is reported. In Chapter 5, we follow-up research of Chapter 4 and the results reveal that the new pentiptycene-containing gold(I) isocyanide complex [Ph-C≡C-Au-C≡N-Phip-OC8H17] adopts a porous supramolecular assembly in solid state and displays novel stimuli-responsive luminescence properties.
