The consumption of illicit drugs has increased exponentially in recent years and has become a problem that worries both governments and international institutions. The rapid emergence of new compounds, their easy access, the low levels at which these substances are able to produce an effect, and their short time of permanence in the organism make it necessary to develop highly rapid, easy, sensitive, and selective methods for their detection. Currently, the most widely used methods for drug detection are based on techniques that require large measurement times, the use of sophisticated equipment, and qualified personnel. Chromo‐ and fluorogenic methods are an alternative to those classical procedures.

“…24 The attractive aspects of organic fluorescent dyes lie in their designable structure, ease of characterization and wide range of available choices. [15][16][17][18][25][26][27] In fact, few commercial fluorescent sensors can operate without their sensing films. [15][16][17][18] It is notable that fluorescent sensing films have great advantages in device manufacture and this makes them more favorable for practical applications.…”

Fluorescence is now a dominant technology and is used extensively in many fields owing to its incomparable properties. On account of its advantages, scientists and engineers have been investigating novel and powerful fluorescent sensors and sensor arrays for real-life applications, in which the construction of highperformance fluorescent films plays a prominent role. The appropriate immobilization of suitable fluorescent sensing elements onto a given substrate is an efficient way to construct usable fluorescent films. Molecular design and film fabrication are two key issues in the development of films because they determine the sensing performance of the films. Via the careful design and selection of sensing fluorophores, the development of convenient film fabrication strategies and the study of the relevant sensing dynamics, a variety of fluorescent sensing films with desirable sensing performance have been developed over at least the last ten years. This review describes recent progress in this important area of science, which combines surface and interface chemistry, photophysics and materials science.High-performance sensing films are the key to real-life usable fluorescent sensors. Different strategies have been developed to fabricate fluorescent sensing films during the previous decades, which mainly include physical coating, doping, single-layer chemistry and molecular gel-based fabrication. The asdeveloped films can be divided into disordered and generally densely packed physical films, 2-dimensional chemical films and 3-dimensional networked physical films. To enhance sensing performance, the structures of films should be optimized both at a molecular level and on a microscopic scale. Therefore, more factors are involved in the design of sensing molecules; in particular, some functional structures need to be introduced to obtain films with favorable adlayer structures. A molecular gel strategy possesses advantages in the fabrication of fluorescent sensing films: 1) increased surface density and effectiveness of sensing sites; 2) increased speed and reversibility of response; and 3) ease of scale-up. However, this strategy is still open to improvement. For example, a general method is urgently needed to increase the adhesive and mechanical strength of gel-based films. Films that were fabricated using the newly developed strategy have found important applications in the sensitive and fast detection of hidden explosives and illegal drugs.
