The first structurally characterized example of a trioxaborinanone () is produced by the reaction of a 9-carbene-9-borafluorene monoanion and carbon dioxide. When compound is heated or irradiated with UV light, carbon monoxide (CO) is released, and a luminescent dioxaborinanone () is formed. Notably, carbon monoxide releasing molecules (CORMs) are of interest for their ability to deliver a specific amount of CO. Due to the turn-on fluorescence observed as a result of the conversion to , CORM serves as a means to optically observe CO loss "by eye" under thermal or photochemical conditions.
第一个结构特征明确的三氧杂硼烷酮（）是通过 9-卡宾-9-硼氟苯单阴离子与二氧化碳反应得到的。当化合物加热或用紫外光照射时，会释放出一氧化碳（CO），形成发光的二氧杂硼烷酮（）。值得注意的是，一氧化碳释放分子（CORM）因其能够输送特定量的 CO 而受到关注。由于观察到转化为的荧光开启，CORM 可作为在热或光化学条件下“用眼睛”光学观察 CO 损失的手段。
