  "id": "MLC-T-CHM-009224",
  "term": "Polyphenylenethynylenes",
  "field": "Chemistry",
  "definition": "A class of conjugated polymers characterized by alternating phenylene (aromatic benzene) and ethynylene (-C≡C-) units in their main chain. The extended pi-electron delocalization along the backbone gives these polymers semiconducting or conducting properties. They are investigated for applications in organic light-emitting diodes (OLEDs), solar cells, and other optoelectronic devices due to their tunable electronic structure.",
