Meniscus-Assisted Solution Printing Enables Cocrystallization in Poly(3-alkylthiophene)-based Blends for Field-Effect Transistors
The formation of cocrystallization in two various conjugated components may endow the newly formed conjugated cocrystals with multiple functionalities and improved charge transport properties. However
compared to conjugated small molecules
this strategy is rather limitedly realized in conjugated polymers. Herein
a simple meniscus-assisted solution printing (MASP) strategy is utilized to achieve the cocrystallization in the blends of two conjugated polymers
i.e.
poly(3-hexylthiophene) (P3HT) and poly(3-octylthiophene) (P3OT)
and the cocrystalline structures are correlated closely to their charge mobilities. The P3HT/P3OT blends phase separate and crystallize individually in their drop-cast thin films. When subjecting the P3HT/P3OT blended solution to MASP
the confined solvent evaporation between two nearly parallel plates triggers them to cocrystallize progressively when accelerating the moving lower plate. The cocrystallization kinetics and the changes in P3HT/P3OT molecular structures are elucidated. Finally
these different crystalline structures of P3HT/P3OT blends are applied in organic field-effect transistors
imparting the cocrystallization-enhanced charge transport than respective P3HT and P3OT crystal domains. Such MASP method can be extended to craft cocrystals of other conjugated polymer blends for their diverse optoelectronic applications.
