Nowadays all over the world considerable attention is focused on development of chemical sensors for the detection of various organic compounds in solutions and gas phase. One of the possible sensor types for organic compounds in solutions detection is optochemotronic sensor - device of liquid-phase optoelectronics that utilize effect of electrogenerated chemiluminescence. In order to enhance selectivity and broaden the range of detected substances the modification of working electrode of optochemotronic cell with organic films is used. Composition and deposition technique of modifying films considerably influence on electrochemical and physical processes in the sensor. 

Electrogenerated chemiluminescence (ECL) has proved to be useful for analytical applications including organic analysis, ECL-based immunosensors, DNA probe assays, and enzymatic biosensors. In the last few years, the electrochemistry and ECL of compound semiconductor nanocrystallites have attracted much attention due to their potential applications in analytical chemistry (ECL sensors).

Some work has been done with fiber-optic-based chemiluminescence sensors. Luminol has been used with various enzymes immobilized on the end of an optical fiber. Sensors based on electrogenerated chemiluminescence with luminol or tris(2,2 -bipyridyl)ruthenium(II) have appeared the latter is particularly attractive due the regenerable nature of the reagent. Importantly, for these applications of liquid-phase chemiluminescence, the reactions are occurring at a reactive surface rather than in a homogeneous solution and as such mass transfer probably controls the overall response.
