Positional Isomeric Thiophene-Based π‑Conjugated Chromophores: Synthesis, Structure, and Optical Properties
{{output}}
A series of positional isomeric chromophores o -TC, m -TC, and p -TC, in which electron-rich thiophene moieties were connected by π-conjugated bridges, were divergently synthesized and characterized. Single-crystal X-ray diffraction analysis revealed an intri... ...
