“…The diffraction peaks at 4.9°, 8.7°, 13.29° and 24.6° can be corresponded to (100), (110), (210) and (001) crystal planes, respectively. 35 The characteristic peak of the (200) crystal plane of TPA–COFs/PANI–20 composite coincides with the characteristic peak of PANI, which further proved that the TPA–COFs/PANI–20 was successfully prepared. 36 All nitrogen adsorption isotherms at 77 K exhibit the characteristic type I isotherm behavior of microporous polymers in Figure 3(d).…”

Covalent organic frameworks (COFs) possess extraordinary porosity, structural diversity, and good electrochemical performance, and have broad application prospects in the field of energy storage. However, the low conductivity of COFs limits its further development. In this paper, the electrochemical performance of triphenylamine-based COFs (TPA-COFs) was improved by compounding with highly conductive polyaniline (PANI) using solvothermal synthesis process. The highly conductive polyaniline fibers can act as conductive path in the composite to accelerate the charge transfer rate of TPA-COFs. The π-π interaction between TPA-COFs and PANI effectively decreases the agglomeration degree of PANI. The good dispersion of composite results in that the specific surface area of TPA-COFs/PANI-20 is high as 1233.9 m2 g−1, which provides rich diffusion channels for electrolyte ions. Moreover, the strong π-π structure in the composites ensures the stability of the material skeleton. Thus, TPA-COFs/PANI composite exhibits excellent rate characteristics and cycling stability.

“…55% at both 740 and 1050 nm, with no degradation of the contrast during 20 switching cycles. COFs exhibiting similar EC device performance were also prepared from diaminoanthraquinone and triformylresorcinol, using functionalized graphene oxide to enhance their conductivity [ 195 ]. S. Halder et al also prepared electrofluorochromic, conjugated polymeric frameworks ( CPF ; Figure 21 ) via the Suzuki coupling of trisphenyltriazine boronic acid with dibromothiophene [ 196 ].…”

In this review, recent advances that exploit the intrinsic emission of organic materials for reversibly modulating their intensity with applied potential are surveyed. Key design strategies that have been adopted during the past five years for developing such electrofluorochromic materials are presented, focusing on molecular fluorophores that are coupled with redox-active moieties, intrinsically electroactive molecular fluorophores, and unconjugated emissive organic polymers. The structural effects, main challenges, and strides toward addressing the limitations of emerging fluorescent materials that are electrochemically responsive are surveyed, along with how these can be adapted for their use in electrofluorochromic devices.
