Specifications | MSDS | Literature and Reviews

PBBTCD, polybenzobisthiadiazole-dithienocyclopentane (CAS number 1334032-14-2), is a small bandgap copolymer (E_g = ~ 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.

For 5 - 10 grams order quantity, the lead time is 4-6 weeks.
