| abstract |
The invention provides sensors comprising one or more compounds of formulae (I) and (II): n [DENDRON 1 ] p -CORE-[[X] r -[DENDRON] m ] n (I) n [DENDRON 1 ] p -[X] r -[DENDRON] q (II) n wherein CORE, X, DENDRON, DENDRON 1 , m, n, p, q and r are as defined herein. The optical (e.g. luminescent) and electronic properties of the compounds are capable of being altered by exposure to a number of different substances. The invention also provides the use of the compounds disclosed above in the sensing of substances, in particular explosives. |
