The adaptability of Pickering emulsions is further augmented through modifications to the properties and composition of the particle emulsifiers, rendering them multifunctional and facilitating efficient reactions between immiscible phases, such as oil and water, especially when the emulsifiers themselves act as catalysts.

However, the exploration of UV NLO crystals is limited by highly transparent functional units. Herein, the polar methylphosphonate unit with large polarizability and polarizability anisotropy, as well as a wide HOMO–LUMO gap, has been used as a new UV NLO building unit for the first time. An excellent UV NLO crystal, [C(NH<small>₂</small>)<small>₃</small>]<small>₂</small>[CH<small>₃</small>PO<small>₃</small>], has been rationally obtained by tuning the polar [CH<small>₃</small>PO<small>₃</small>] units into an ordered arrangement with the π-conjugated [C(NH<small>₂</small>)<small>₃</small>]<small>⁺</small> cations. Remarkably, [C(NH<small>₂</small>)<small>₃</small>]<small>₂</small>[CH<small>₃</small>PO<small>₃</small>] exhibits good balance among three key NLO properties, including a short UV cutoff edge extending to 207 nm, a moderate phase-matching second-harmonic generation (SHG) response of 1 × KH<small>₂</small>PO<small>₄</small> (KDP), and a suitable birefringence of 0.053@1064 nm.

More importantly, the [C(NH<small>₂</small>)<small>₃</small>]<small>₂</small>[CH<small>₃</small>PO<small>₃</small>] crystal can easily grow up to a large size of 5.4 × 3.8 × 3 mm<small>³</small> in view of its facile crystal growth behavior. Both crystal structure and theoretical calculations demonstrate that the SHG response of [C(NH<small>₂</small>)<small>₃</small>]<small>₂</small>[CH<small>₃</small>PO<small>₃</small>] mainly originates from the ordered arrangement of the polar [CH<small>₃</small>PO<small>₃</small>] units.
