研究目的
To study the effect of length of the alkyl side chain on the performance of n-type organic field-effect transistors (OFETs) based on naphthalene diimide and bithiophene vinylene bithiophene copolymers.
研究成果
The study successfully synthesized two NDI-based n-channel polymers with different side chains and demonstrated that increasing the alkyl side chain length from 24 to 28 carbon atoms improves transistor performance due to better solubility and crystallinity.
研究不足
The study focused on the effect of alkyl side chain length on OFET performance but did not explore other potential modifications to the polymer structure that could further enhance device performance.
1：Experimental Design and Method Selection:
The study involved the synthesis of two copolymers via Stille-coupling polymerization reaction to investigate the effect of alkyl side chain length on OFET performance.
2：Sample Selection and Data Sources:
The copolymers were characterized using thermal, optical, and electrochemical properties, and their performance in OFETs was evaluated.
3：List of Experimental Equipment and Materials:
Instruments used included a Bruker Avance-300 MHz and Bruker 500 FT-NMR spectrometer, TA instruments 2050 thermogravimetric analyzer, Shimadsu UV-1065PC UV-visible spectrophotometer, and Keithley 4200-SCS semiconductor parameter analyzer.
4：Experimental Procedures and Operational Workflow:
The polymers were synthesized, purified, and then used to fabricate OFETs, which were characterized for their electrical properties.
5：Data Analysis Methods:
The field-effect mobility and threshold mobility were calculated using the gradual channel approximation equation.
