Organoborylazadipyrromethenes were synthesized from free base and fluoroborylazadipyrromethenes and characterized with regard to their structural and electronic properties. B-N bond lengths, along with photophysical and redox behavior, appear dependent on the effective electronegativity at the boron atom as tuned by its substituents, with stronger electronegativity correlating to a shorter B-N bond length, red-shifted absorbance, enhanced fluorescence lifetime and yield, and positively shifted redox potentials.

- Fullerene and acenequinone compounds were studied as electron mediators between a p-type semiconductive polymer and n-type oxide semiconductors for enhancing solar cell efficiency.
- The research found that these sensitizers worked better with titanium dioxide than zinc oxide due to different dipole-induced vacuum level shifts impacting the conduction band.
- Observations indicate that in titanium dioxide cells, sensitizers can enhance photovoltage and overall efficiency, while in zinc oxide cells, they tend to be less effective due to shifts in the conduction band, guiding future design of photocells.
