The invention describes electrically conductive shaped bodies with an inherent positive temperature coefficient (PTC), produced from a composition which contains at least one organic matrix polymer (compound component A), at least one submicroscale or nanoscale, electrically conductive additive (compound component B) and at least one phase-change material with a phase-transition temperature in the range from &#x2212;42&#xb0; C. to +150&#xb0; C. (compound component D). The phase-change material is incorporated into an organic network (compound component C). The electrically conductive shaped body with an inherent PTC effect is, in particular, a filament, a fibre, a spun-bonded web, a foam, a film, a foil or an injection-moulded article. The switching point for the PTC behavior is dependent on the type and also the phase-conversion temperature of the phase-change material. By way of example, a self-regulating surface heater in the form of a film, foil and/or textile can be realized in this way.

Disclosed are pyridinyl-isoquinoline-dione derivatives, methods of producing these derivatives, conjugates comprising the pyridinyl-isoquinoline dione derivatives and (i) a solid support, or (ii) a biomolecule, methods of producing these conjugates as well as the use of these conjugates as quenchers in fluorescence resonance energy transfer (FRET).
