Herein, we present a new series of CuI-based hybrid materials with tunable structures and semiconducting properties. The CuI inorganic modules can be tailored into a one-dimensional (1D) chain and two-dimensional (2D) layer and confined/stabilized in coordination frameworks of potassium isonicotinic acid (HINA) and its derivatives (HINA-R, R = OH, NO2, and COOH). The resulting CuI-based hybrid materials exhibit interesting semiconducting behaviors associated with the dimensionality of the inorganic module; for instance, the structures containing the 2D-CuI module demonstrate significantly enhanced photoconductivity with a maximum increase of five orders of magnitude compared to that of the structures containing the 1D-CuI module. They also represent the first CuI-bearing hybrid chemiresistive gas sensors for NO2 with boosted sensing performance and sensitivity at multiple orders of magnitude over that of the pristine CuI. Particularly, the sensing ability of CuI-K-INA containing both 1D- and 2D-CuI modules is comparable to those of the best NO2 chemiresistors reported thus far.

通过协调组装将 1D 链和 2D 分层 CuI 模块限制在 K-INA-R 框架中：结构调节和半导体调节
在此，我们提出了一系列具有可调结构和半导体特性的新型 CuI 基混合材料。CuI无机模块可以定制为一维（1D）链和二维（2D）层，并限制/稳定在异烟酸钾（HINA）及其衍生物（HINA-R，R = OH， NO 2和COOH)。由此产生的 CuI 基杂化材料表现出与无机模块的维度相关的有趣的半导体行为；例如，包含 2D-CuI 模块的结构表现出显着增强的光电导性，与包含 1D-CuI 模块的结构相比，最大增加了五个数量级。它们还代表了首款用于 NO 2的含 CuI 混合化学电阻气体传感器，其传感性能和灵敏度比原始 CuI 提高了多个数量级。特别是，同时包含 1D-和 2D-CuI 模块的 CuI-K-INA 的传感能力可与迄今为止报道的最佳 NO 2化学电阻器相媲美。
