  • Significant progress has been realized in the design and synthesis of light emitting polymers with emission over the whole range of the visible spectrum. However up to seventy-five percent of charge recombination events can lead to triplet states that decay non-radiatively. Following the pioneering work in the field of small molecule organic light emitting devices it has been found that solution processible iridium polymer complexes can be used to harness the wasted triplet energy. In this paper new results concerning electrophosphorescence of solution processible tethered iridium polymer derivatives will be presented. Furthermore our approaches to the design of new high triplet energy conjugated polymer hosts will be reported.

  • Phenylethanoids, including 2-phenylethanol, tyrosol, and salidroside are a group of phenolic compounds with a C6-C2 carbon skeleton synthesized by plants. Phenylethanoids display a variety of biological activities, including antibacterial, anticancer, anti-inflammatory, neuroprotective, and anti-asthmatic activities. Recently, successful microbial synthesis of phenylethanoids through metabolic engineering and synthetic biology approaches has been reported and could allow phenylethanoid production from alternative microbial sources. Here, we review the recent achievements in the synthesis of phenylethanoids by microorganisms. The work done so far will contribute to the production of diverse phenylethanoids using various microbial systems and facilitate exploration of further diverse biological activities of phenylethanoids.
