PBBTCD, high quality semiconducting polymer

High purity and available online for priority dispatch

PBBTCD, polybenzobisthiadiazole-dithienocyclopentane, is a small bandgap copolymer (Eg = ~ 0.6 eV) with a backbone alternating electron donating cyclopentadithiophene (CDT) and electron accepting fused-ring benzobisthiadiazole (BBT) units.

High charge mobilities were observed to be 0.076 cm2 V-1 s-1 for electrons and 0.10 cm2 V-1 s-1 for holes for PBBTCD due to its planar structure and orderly packed structure in film. The balanced ambipolarity of the BBT moiety of the polymer makes it a good candidate for logic circuit applications.
