Polarization Properties Orientation Coupling Regulates Molecular Packing and Device Performance Beyond Dipole Moment Strength in Organic Solar Cells

ABSTRACT Strong interactions between large dipole moment additives and host materials have been widely used to modulate molecular packing in organic solar cells (OSCs), while most studies focuses on dipole moment magnitude instead of the polarization properties orientation. Here,...

Thermo-optical properties of polyimide films with bulky side groups: Experimental and theoretical investigations

In this study, we report the design and synthesis of two novel diamine monomers: hydroxyl-containing 4-(bis(4-amino-3,5-dimethylphenyl) methyl) phenol ( HGDT ) and pyridine-functionalized 4,4’-(pyridin-4-ylmethylene) bis(2,6-dimethylaniline) ( PYDT ). These monomers were copolyme...
