This paper highlights advances made using the 4-bora-3a,4a-diaza-s-indacene (BODIPY) as a fluorophore in design and application of fluorescent sensors for microenvironment polarity. Sections of the paper cover broad analysis of a range of fluorescent indicators immobilized in ethyl-and methyl cellulose matrices. The present study demonstrates that BODIPYbased fluorescent materials could be successfully utilized for ratiometric detection of ethanol and acetone in gas phase. The achieved limit of detection value equals 0.02 mg/ml for acetone and 0.08 mg/ml for ethanol, whereas obtained sensoric materials are reusable without regeneration required.

Hybrid materails with dipyrrin based luminophores are of major interest in different areas of material chemistry, sensors and photovoltaics. Vast variety of the materials with BODIPY motif were synthesized and investigated up to date. Modern trend in the material chemistry is the aimed functionalization of them by immobilizing in their structure an active components. Based on interactions between matrix and dye we can control spectral and photophysical characteristics of hybrid material for tuning practically valuable properties for specific tasks. Presented paper summarize the results of our research group, working in the field of hybrid materials with BODIPY dyes: synthesis, spectral characteristics evaluation and possibilities of practical application investigation. Discussion is focused on the methods of synthesis of materials and practical application of them as sensors for pH, polarity and in OLED devices.
