A magnetic particle-polymer hybrid material can include: a substance having a structure of Formula 1 or derivative or salt thereof: Z(L-FP)(Formula 1), wherein: Z is a magnetic particle smaller than 1 mm; m is a positive integer and defines the number of (L-FP) coupled to the Z; L is a linker linked to the magnetic particle; FP is a functionalized polymer having: a first structure derived from a first norbornene compound linked to the magnetic particle through the L; and one or more monomeric units each including a second structure derived from a second norbornene compound, where one of the monomeric units is linked to the first structure through a saturated or unsaturated alkyl, each monomeric unit includes a functional group capable of binding with another substance.

The invention relates to a method for identifying an object comprising at least one object identifier with an object code that is used to verify the authenticity of the object. The method comprises the following steps: creation of a unique random system code consisting of a first and a second system code, the first part of the system code being generated from a first character set by a first random method and the second part of the system code being generated from a second character set by a second random method and saving of the system code together with at least one first object-specific information in a first data memory, the first part of the system code being encrypted by a first encryption method and the second part of the system code by a second encryption method prior to being saved; creation of a random encryption key from a third character set by a third random method, creation of a unique assignment identifier by an assignment method and saving of the encryption key, assignment identifier and at least one second object-specific piece of information in a second data memory; creation of the object code, consisting of the first part of the system code and the assignment key, encryption of the object identifier by a fourth encryption method and saving of the encrypted system code together with the encrypted object identifier in a third data memory; and attachment of the object code to the object.

Method and device for identifying objects

The present invention relates to compounds which can be used in particular as ligands, to complexes of formula (I) and (II) and also to light-emitting devices and in particular to organic light-emitting devices (OLEDs). In particular, the invention relates to the use of luminescent oxazole-chelate metal complexes as emitters in such devices.
