ABSTRACT:
The invention provides sensors comprising one or more compounds of formulae (I) and (II):in-line-formulae description="In-line Formulae" end="lead"?[DENDRON1]p-CORE-[[X]r-[DENDRON]m]n  (I)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?[DENDRON1]p-[X]r-[DENDRON]q  (II)in-line-formulae description="In-line Formulae" end="tail"?wherein CORE, X, DENDRON, DENDRON1, 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.
