    Synthesis and characterization of naphthalimide-functionalized polynorbornenes

    Highly fluorescent and photostable (2-alkyl)-1H-benzo[de]isoquinoline-1,3(2H)-diones with a polymerizable norbornene scaffold have been synthesized and polymerized using ring-opening metathesis polymerization. Th...

    Enabling luminescence decay time-based sensing using integrated organic photodiodes

    The use of organic photodiodes (OPDs) for measuring phosphorescent lifetimes of optochemical oxygen sensors is described. Phosphorescent indicators with lifetimes ranging from ∼5 to 60 μs have been studied usi...

    Screen-printed polymer waveguides for integrated optics

    We demonstrate screen printing of polymer waveguides on rigid and flexible substrates. The waveguides are characterized by optical microscopy and propagation losses are determined by cut-back measurements. Fur...

    Filter-free integrated sensor array based on luminescence and absorbance measurements using ring-shaped organic photodiodes

    An optical waveguiding sensor array featuring monolithically integrated organic photodiodes as integrated photo-detector, which simplifies the readout system by minimizing the required parts, is presented. The...
