Key Points

The research aims to investigate how homoconjugation affects the photophysical properties of donor-acceptor triptycenes through the interactions between charge transfer and exciton states.
Utilized various spectroscopic techniques to analyze the optical properties of organic chromophores.
Investigated the impact of intramolecular charge transfer on spectrum edges using donor-acceptor triptycenes.
Enhanced optical properties were observed with specific shifts in absorbance bands, indicating efficient charge transfer.
Notable improvements in solar absorbance performance were reported, highlighting the potential for solar energy applications.

Implication

Explores optical property enhancements in donor-acceptor triptycenes, suggesting novel strategies for chromophore development.

Abstract

Strategies for tuning the optical properties of organic chromophores generally focus on shifting the edges of the spectrum: this might be red-shifting the longest absorbance band to improve solar absorbance,...
