In this talk, I will present, with some examples, our recent studies on the development of novel fluorescence sensing films and the relevant instrument creation [1].The topics may include: (1) single-layer chemistry approach [2];(2) conjugated polymer/oligomer-based fluorescent films [3], and (3) potable and vehicular instruments for explosive detection [4].During the presentation, emphases will be given to: (1) "two-dimensional solution model" or "spacer-layer screening/enrichment effect", which determines, to a great degree, the selectivity and sensitivity of a sensing film, and (2) the strategy of side-chain modification, which has been used for the creation of both conjugated polymer/oligomer and single-layer chemistry-based fluorescent films.
