PNDI(2HD)2T is now available featuring:

  • Higher molecular weights and high purityPNDI(2HD)2T is purified via Soxhlet extraction with methanol, hexane and chlorobenzene under an argon atmosphere - higher molecular weights and higher purity normally gives better device performance
  • Larger-quantity orders (so you can plan your experiments with polymers from the same batch)

Chemical structure and product image of PNDI(2HD)2T; Chemical formula: (C54H72N2O4S2)n.



PNDI(2HD)2T, also known as P(NDI2HD-T2), copolymer of naphtalene and bithiophene, is used as a polymer acceptor in high performance all-PSCs.

Compared to PNDI(2OD)2T, PNDI(2HD)2T exhibits a higher degree of crystalline behaviours. This facilitates superior 3D charge-transport between polymer donor and acceptor materials, resulting in enhanced device performance for all-PSCs. 

When PNDI-bithiophene copolymers with different side-chain length were compared, the maximum µe,FET value was identified as 0.39, 1.22 and 1.90 cm2 V−1 s−1 for PNDI(2DT)2T, PNDI(2OD)2T, and PNDI(2HD)2T respectively [2].
