The photophysical and photoprototropic behaviour of 4-aminobiphenyl (4ABP) in aqueous β-cyclodextrin (β-CDx) solution has been investigated using steady-state and time-resolved fluorescence spectroscopy. Fluorescence of the neutral form of 4ABP is enhanced due to the formation of a 1:1 complex with β-CDx. The formation of this complex has been confirmed by time-resolved spectroscopy. In the presence of β-CDx, no change was observed in the ground state pKa value but the excited state pKa value changed. Based on its photophysical and photoprototropic characteristics in β-CDx, the structure of the 1:1 inclusion complex is proposed.

Potential Applications

The photophysical properties of the confined dye inside the γ-CD in presence of Au nanoparticles have been studied by steady state and time resolved spectroscopy. It is found that the photoluminescence quenching of C480 dye increases from 26% to 49% due to confinement of dye inside γ-CD. The designing of such new optical based materials having coumarin 480 dye inside the γ-CD in presence of Au nanoparticles may have potential applications for light harvesting system.
