Local Order Is Not Enough: Synthetically Accessible Polymers Reveal the Role of Side‐chain Branching Point in Organic Solar Cell and Transistor Performance
Side‐chain engineering provides a powerful strategy for controlling the microstructure and electronic properties of conjugated polymers, but improved crystalline order does not necessarily translate into enhanced device performance. To investigate this, a homologous series of donor polymers, FO6‐T, 3‐FO6‐T, 4‐FO6‐T, an...
