An inexpensive fiberoptic-based formaldehyde field sensor is described for monitoring low-levels of formaldehyde, a widespread indoor air pollutant, based on the principle of evanescent wave absorption of light. Operating at an optimal temperature of 210 °C, the sensor exhibits high. In this paper, a decaboryl derivative formaldehyde fluorescent probe (M1) was synthesized for the first time by introducing a 5-amino-isoquinoline group into a decaborane parent. Using theoretical calculations, 1 H-NMR, 11 B-NMR, HR-MS, and FT-IR, the molecular structure of the probe was determined. Fiber optic metal oxide (MO) semiconductor sensors have so increased the utility and demand for optical sensors in a variety of military, industrial, and social applications. Therefore, the development of formaldehyde detection methods is fundamental. For this purpose, optical sensors are used, which are.
