## Description

- description: This study examines the optical and electronic properties of eight
    2D transition metal chalcogenides (TMDs) covalently functionalized with perylene,
    forming hybrid materials. Characterization was performed using XPS, Raman, EDX,
    TEM, and AFM, while UV-Vis-NIR absorption and photoluminescence spectroscopy assessed
    optical properties. Electronic properties were analyzed via cyclic voltammetry
    and FET devices. The results showed that perylene’s spectroscopic features dominate,
    with WSe₂ and MoSe₂ exhibiting a new near-IR band and MoTe₂ showing enhanced conductivity.
    Perylene also boosted absorption (400–600 nm), improving photoresponse, with responsivities
    over 2 × 10⁵ % and 2 × 10⁴ mA W⁻¹. These hybrids rival top non-covalent functionalization
    methods, emphasizing covalent functionalization’s potential for tuning 2D materials.
