“…TIPS pentacene was employed as an example to blend with PFS because of its well-known solution processing and charge transport properties. Metal-containing polymers or metallopolymers [ 32 ] provide unique metal-involved intermolecular interactions that can result in novel electrical properties, which have not been utilized previously in mediated organic crystal growth as far as we know. Without the aid of external alignment techniques, we showed that the orientation of TIPS pentacene bulk crystals can be facilely aligned along the tilted direction of the substrate.…”

In this study, we demonstrated for the first time that a metal-containing semicrystalline polymer was used as an additive to mediate the thin film morphology of solution-grown, small-molecule organic semiconductors. By mixing polyferrocenylsilane (PFS) with an extensively-studied organic semiconductor 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS pentacene), PFS as a semicrystalline polymer independently forms nucleation and crystallization while simultaneously ameliorating diffusivity of the blend system and tuning the surface energies as a result of its partially amorphous property. We discovered that the resultant blend film exhibited a 6-fold reduction in crystal misorientation angle and a 3-fold enlargement in average grain width. Enhanced crystal orientation considerably reduces mobility variation, while minimized defects and trap centers located at grain boundaries lessen the adverse impact on the charge transport. Consequently, bottom-gate, top-contact organic thin film transistors (OTFTs) based on the TIPS pentacene/PFS mixture yielded a 40% increase in performance consistency (represented by the ratio of average mobility to the standard deviation of mobility). The PFS semicrystalline polymer-controlled crystallization can be used to regulate the thin film morphology of other high-performance organic semiconductors and shed light on applications in organic electronic devices.

“…Graft copolymerization is based on the existance of free radicals in an existing cellulose chains. The free radicals can be induced by various initiation methods such as ultraviolet and ionizing radiation [2][3][4][5][6][7]. Grafting of irradiated cellulose has the low grafting effeciency, i.e.…”
