摘要:
The invention relates to chemical sensors comprising fluorescent conjugated polymers as sensitive materials and to their use in detecting or assaying nitro compounds, in particular nitroaromatic compounds. Fields of application: detection of explosives, monitoring and observation of atmospheric pollution and of the quality of relatively confined surroundings, watching over industrial sites.
摘要:
The invention relates to a chromophore of general formula: in which: R1 represents C1-C4 alkyl; R2 represents a sterically hindered group; R3 represents a pi-conjugated system; Y represents O, S, NH or is absent; R4 represents a C3-C18, preferably C3-C8 and more preferably C3 alkyl group; M represents a metal from Group III or IV of the Periodic Table; n is an integer, to its process of preparation and to its uses.

摘要:
The invention relates to a process for the hydrolysis-polycondensation of a sterically hindered crosslinkable chromophore, characterized in that the hydrolysis-polycondensation is catalyzed with an acid released by a photoacid generator (PAG).
