Thermo-responsive light-emitting metal complexes and related materials

Composite Materials of Thermo-responsive Polymer Networks and Inorganic Nanoparticles

The focus of this work is on composite materials of inorganic nanoparticles such as TiO2 embedded within microspheres of a responsive polymeric network. Microgels of N-isopropylacrylamide (NIPAM) with interpenetrating (IP) linear chains of poly(acrylic acid) (PAAc) were synthesized to promote the incorporation of TiO2. Dynamic light scattering measurements of the IP-microgels in aqueous environ...

Thermo- and light responsive micellation of azobenzene containing block copolymers.

In this communication, the synthesis and characterization of thermo- and light responsive block copolymers is reported. PEO-b-PNIPAM polymers with azobenzene moieties were prepared and analyzed by turbidimetry, fluorescence, NMR and DLS measurements. A temperature controlled reversible formation as well as a light induced disruption and reformation of micellar structures in water was found.

Light-Emitting Porous Silicon: Materials Science, Properties, and Device Applications

Silicon-based. light-emitting devices (LED's) should find numerous uses in optoelectronics. For example, the integration of silicon LED's with silicon microelectronics could lead to reliable and inexpensive optical displays and optical interconnects. Until recently, however, it had not been possible to obtain efficient room-temperature luminescence from silicon. The demonstration in 1990 that a...

Device Structures and Materials for Organic Light Emitting Diodes

Organic light emitting devices (OLEDs) are promising candidates for light-weight color flat panel displays. Different device structures with emission in the blue, green, and red spectral region are discussed with respect to their optical and electrical characteristics. Blue OLEDs based on OXD-8 as emitter molecule show quantum efficiencies of 0.9 % (2.2 cd/A, 0.6 lm/W), green emitting devices b...
