This study includes the synthesis and application of unsymmetrical zinc phthalocyanines ( ZnPcs ) 1 and 2 with three tertiary‐butylated ( tBu ) and hexyl‐tridecafluoro ( C 6 F 13 ) groups that are further connected with carbon nanotubes ( CNTs ) through an amide bonding to yield Pc‐functionalized CNTs 3 and 4 , respectively. The properties of the resulting Pc‐ CNT complexes are thoroughly investigated using various analytical techniques, revealing that 3 and 4 enhanced the dispersion and adhesion properties of the CNTs to poly(vinylidene fluoride) ( PVDF ) matrix, and thereby improved the electrical and dielectric properties. Particularly, the presence of long and fluorinated substituents in 4 allowed for better interfacial compatibility compared to alkylated Pc‐ CNT 3 , leading to more stable dielectric behaviors. Our work has demonstrated that perfluorinated and alkylated Pc‐ CNT complex could be facile and effective approach toward high‐performance polymer‐based dielectrics.
