“…Finally, electrochemical polymerization of carbazole‐containing PDI chromophores has been utilized to fabricate a film comprised of networked PDIs for electrochromic application. Although the solvent resistance of the film was not described, it can be assumed that the highly cross‐linked nature of the polymer should enable the film to tolerate solvent processing …”

Because of their unique structural and optical properties, 1D perylene diimide (PDI) derivatives have gained attention for use in optoelectronic devices. However, PDI‐containing self‐assembled supramolecular systems often are of limited use because they have supramolecular architectures that are held together by weak noncovalent π–π stacking, hydrogen bonding, and hydrophobic interactions. As a result, they are intrinsically unstable under solution‐processing conditions. To overcome this limitation, a polydiacetylene (PDA)‐based strategy is developed to construct a solvent‐resistant and stable PDI assembly. For this purpose, first the monomer PDI–BisDA is generated, in which two polymerizable diacetylene (DA) units are covalently linked to a PDI core. Importantly, 254 nm UV irradiation of self‐assembled PDI–BisDA nanofibers forms solvent‐resistant and stable PDI–PDA fibers. Owing to the presence of PDA, the generated polymer fibers display an increased photocurrent. In addition, the existence of PDA and PDI moieties in the fiber leads to the occurrence of switchable on–off fluorescence resonance energy transfer (FRET) between the PDI and reversibly thermochromic PDA chromophores.

“…14 PDIs are also advantageous due to their high absorption ability, high photochemical and optical stability, reversible redox properties, ease of synthetic modication and excellent environmental/thermal stability. [15][16][17] PDI based molecules and polymers have progressively attracted signicant attention in applications such as light-emitting diodes, 18 sensors, 19 organic eld-effect transistors, 20,21 light-harvesting arrays, 22 molecular wires, 23 photochromic materials 24 and photovoltaic cells. 25,26 Further, in PDI unit, the optical, electrochemical and charge transport properties can be tailored by introduction of appropriate substituents at the N-positions 26,27 or at the perylene bay positions, 28,29 offering wider scope for tuning the optical as well as processing properties.…”

“…35,36 The current rise around −0.5 V was caused by the reduction of PBI core. 37 To maintain the independence of the PBI core, the deposition potential range was determined to be 0.23 to 1.38 V, as Figure 1b shows. As the number of cycles increased, the forward oxidation current and the backward reduction current increased continually, indicating the gradual deposition of polymerfilmonthesubstrate.…”

Cathodic electrochromic materials realized by n-type doping of conducting polymers are scarce. Even with limited cases reported in the literature, long-term stability is an urgent problem to be solved. Herein, we report a high performance and stable cathodic electrochromic material, poly(Th-Cl-PBI), based on a perylene bisimide function core. Due to its high electropolymerization efficiency and low steric hindrance of thiophene groups, perylene bisimide, which generally does not dissolve and form film easily, can grow to the sufficient thickness of 350 nm for wide-range spectral modulation and large-capacity energy storage. The optical contrast of optimized film with a thickness of 240 nm reaches as high as 69.1% at 520 nm, 94.1% at 760 nm, and 95.7% at 680 nm. Theoretical simulation based on the Lambert-Beer law also verifies this optical contrast dependent on film thickness. Besides, during the transition between the neutral state and radical anion state, it maintains 90.2% of the electrochemical activity after 4000 cycles, and the transmittance spectrum remains stable after 2000 cycles. The cation size effect on cathodic electrochromic process and cyclic stability has been investigated.
