Bandgap and Molecular‐Energy‐Level Control of Conjugated‐Polymer Photovoltaic Materials Based on 6,12‐Dihydro‐diindeno[1,2‐b;10,20‐e]pyrazine
Abstract Six conjugated polymers based on the indenopyrazine ( IPY) unit are designed and synthesized by copolymerization with different electron‐deficient and electron‐rich building blocks. All of the polymers show good solubility, excellent film‐forming ability, and low‐lying highest occupied mole...
