We first introduce how the microstructure of conjugated polymer films evolves with molecular weight in terms of solution aggregation, chain entanglement and phase separation. Next, we discuss the impact of molecular weight on the electrical performance of conjugated polymer films by analyzing the intrachain and interchain charge transport behaviors.

In recent years, self-assembled monolayers (SAMs) have been demonstrated to be effective as hole transport materials for photovoltaic devices to boost both efficiency and stability. Nevertheless, research on SAM-based interface engineering to optimize the photodetection is still rarely reported. In this study, by choosing different SAMs to replace the traditional poly(bis(4-phenyl)(2,4,6-trimethylphenyl)amine) (<strong>PTAA</strong>) hole transport layer (HTL) for PPD fabrication, we find that the dark current level is more determined by the highest occupied molecular orbital (HOMO) level of HTLs, rather than the crystallinity of perovskite layers. Moreover, the SAM HTLs significantly improved the response speed of the PPDs with the tunneling hole transporting properties and enhanced built-in potential with the induced interface dipole. In comparison to the <strong>PTAA</strong> based PPDs, the dark current level of (4-(7<em>H</em>-dibenzo[<em>c</em>,<em>g</em>]carbazol-7-yl)butyl) phosphonic acid (<strong>4PADCB</strong>) modified devices was reduced to 1.44 × 10<small>⁻⁹</small> A cm<small>⁻²</small>, the response rise/fall time was optimized from 901 ns/1.89 μs to 546/334 ns (both with an effective area of 6 mm<small>²</small>), and they exhibited a peak specific detectivity of 1.67 × 10<small>¹³</small> Jones and high operational stability.

Such interactions frequently produce low-dimensional band structures that are susceptible to perturbation and to lose the electrical conductivity. To extend the intra- and intercolumnar interactions, heteroatoms such as chalcogen atoms are often introduced at the periphery of the constituent molecules. Yet this strategy inevitably encounters difficulties, as such molecules would be more and more difficult to synthesize with increasing the number of heteroatoms and the molecular weights, while they would still produce highly anisotropic conductors. Herein, we report an extended intermolecular interaction pattern in a newly synthesized charge-transfer complex (EtHAC)<small>₂</small>I<small>₃</small>, which includes ten ethyl groups around the periphery of its fused aromatic rings HAC. The (EtHAC)<small>₂</small>I<small>₃</small> crystal contains columns of stable EtHAC radical cations with intercolumnar interactions by Et–Et contacts. Theoretical calculations indicate that intramolecular Et-HAC and intermolecular Et–Et interactions enable formation of three-dimensional (3D) EtHAC network. Additionally, charge-transfer interactions <em>via</em> Et–I contacts lead to carrier doping into the EtHAC network. These effects are combined to produce a stable 3D metallic ground state, accounting for their high 3D electrical conductivity (<em>ca.</em> 10–2500 S cm<small>⁻¹</small>) down to ∼2 K. The unique metallic properties of (EtHAC)<small>₂</small>I<small>₃</small> are further corroborated by the calculated band structures and polarized reflectance spectra, both indicating 3D metallic characteristics. The electron spin resonance spectra of (EtHAC)<small>₂</small>I<small>₃</small> suggest that the highly mobile unpaired electrons behave as if they are free electrons with long relaxation times.
