2D organic crystals play a unique role in photodetection owing to their tunable detection wavelength, low manufacturing cost, compatibility with lightweight, and controllable synthesis. However, their detection wavelength range mainly encompasses the visible (Vis) and near-infrared (NIR) spectra. Herein, 2D erucamide crystals are synthesized using nitrogen gas and methanol as raw materials without catalysts at room temperature under atmospheric pressure via laser processing. The synthesized 2D erucamide is demonstrated to be a promising broad bandgap organic semiconductor material. A UV photodetector made of 2D erucamide exhibited a responsivity as high as 145 mA W−1, a millisecond-level response speed, and an excellent detectivity of 4.96 × 109 Jones. Furthermore, the synthesized erucamide showed an excellent UV–vis suppression ratio (R254 nm/R532 nm) of 59. The synthesis mechanism of erucamide via laser bubbling in liquids is proposed. Thermodynamically, the high temperature of the bubbles is beneficial for nitrogen and methanol decomposition. Kinetically, rapid bubble quenching facilitates final product formation. This accomplishment represented the pioneering utilization of lasers in converting nitrogen gas into organic compounds while introducing 2D erucamide into the realm of organic UV photodetectors.

二维芥酸酰胺晶体合成和紫外光电检测
二维有机晶体由于其检测波长可调、制造成本低、轻量化、合成可控等特点，在光电检测中发挥着独特的作用。然而，它们的检测波长范围主要涵盖可见光 (Vis) 和近红外 (NIR) 光谱。本文以氮气和甲醇为原料，在室温、大气压下，在无催化剂的情况下，通过激光加工合成了二维芥酸酰胺晶体。合成的二维芥酸酰胺被证明是一种有前途的宽带隙有机半导体材料。由2D芥酸酰胺制成的紫外光电探测器表现出高达145 mA W −1 的响应度、毫秒级的响应速度以及4.96×10 9 Jones的优异探测灵敏度。此外，合成的芥酸酰胺表现出优异的紫外可见光抑制比（R 254 nm/R 532 nm）为59。提出了通过液体中激光鼓泡合成芥酸酰胺的机理。从热力学角度来说，气泡的高温有利于氮气和甲醇的分解。从动力学上讲，快速气泡猝灭有利于最终产品的形成。这一成就代表了激光在将氮气转化为有机化合物方面的开创性应用，同时将二维芥酸酰胺引入有机紫外光电探测器领域。
