Vacuum-Sublimed Cocrystalline Thin Films of Naphthalene Bisimide and Pt(II) Complex for Phosphorescent Light-Emitting Diodes
<p>Additional data to report <a href="https://doi.org/10.1002/adom.202402117">https://doi.org/10.1002/adom.202402117</a>:</p> <p>Cocrystals employing small organic molecules with platinum(II)-complexes are known to exhibit organic room-temperature phosphorescence (RTP). However, this desirable property was so far only demonstrated in the macroscopic 1:1 cocrystalline state, which limitsdevice applications outside of small single-crystal devices. Here, we show that vacuum cosublimed thin films of both components in various mixing ratios form layers with selfassembled small cocrystalline domains which exhibit RTP. This Pt(II) doping improved the photoluminescence (PL) quantum yield (ΦPL) of the now phosphorescence emitting 1,8:4,5-naphthalene bisimide (NBI) from below 0.1% to 9% in respective thin films. These doped layers were employed as active layers in light-emitting diodes to emit red electroluminescence (EL). Via time-resolved measurements the lifetime of the device EL was determined in accordance with the PL to be around 50 µs. Maximum external quantum efficiencies (EQEs) of over 0.2% with RTP emission signatures consistent with the PL of solution-grown cocrystals could be achieved.</p>

First-principles simulations of exciton transfer between N-heterocyclic carbene iridium (III) complexes in blue organic light-emitting diodes
<p>N-heterocyclic carbene (NHC) iridium (III) complexes are promising for the use as blue emitters in organic light-emitting diodes. Exciton transfer between such organometallic complexes is investigated using time-dependent density functional theory calculations. Casida's equation is solved to study absorption and emission of the neutral and charged complexes using the ORCA package. The Sternheimer equation implemented in the Octopus code is extended to take into account spin-orbit coupling and is applied to investigate triplet excitations. Real-time propagation as implemented in the Octopus code is used to simulate exciton dynamics in an emitter dimer and to extract the exciton coupling via explicit integration of transition densities.</p>

Long-living and highly efficient bio-hybrid light-emitting diodes with zero-thermal-quenching biophosphors
<p>Bio-hybrid light-emitting diodes (Bio-HLEDs) based on color down-converting filters with fluorescent proteins (FPs) have achieved moderate efficiencies (50 lm/W) and stabilities (300 h) due to both thermal- and photo-degradation. Here, we present a significant enhancement in efficiency (~130 lm/W) and stability (>150 days) using a zero-thermalquenching bio-phosphor design. This is achieved shielding the FP surface with a hydrophilic polymer allowing their homogenous integration into the network of a light-guiding and hydrophobic host polymer. We rationalize how the control of the mechanical and optical features of this bio-phosphor is paramount towards highly stable and efficient Bio-HLEDs, regardless of the operation conditions. This is validated by the relationships between the stiffness of the FP-polymer phosphor and the maximum temperature reached under device operation as well as the transmittance of the filters and device efficiency.</p>
Data from: Transition from conventional to light-emitting diode street lighting changes activity of urban bats
Light pollution is rapidly increasing and can have deleterious effects on biodiversity, yet light types differ in their effect on wildlife. Among the light types used for street lamps, light-emitting diodes (LEDs) are expected to become globally predominant within the next few years. In a large-scale field experiment, we recorded bat activity at 46 street lights for 12 nights each and investigated how the widespread replacement of conventional illuminants by LEDs affects urban bats: we compared bat activity at municipal mercury vapour (MV) street lamps that were replaced by LEDs with control sites that were not changed. Pipistrellus pipistrellus was the most frequently recorded species; it was 45% less active at LEDs than at MV street lamps, but the activity did not depend on illuminance level. Light type did not affect the activity of Pipistrellus nathusii, Pipistrellus pygmaeus or bats in the Nyctalus/Eptesicus/Vespertilio (NEV) group, yet the activity of P. nathusii increased with illuminance level. Bats of the genus Myotis increased activity 4·5-fold at LEDs compared with MV lights, but illuminance level had no effect. Decreased activity of P. pipistrellus, which are considered light tolerant, probably paralleled insect densities around lights. Further, our results suggest that LEDs may be less repelling for light-averse Myotis spp. than MV lights. Accordingly, the transition from conventional lighting techniques to LEDs may greatly alter the anthropogenic impact of artificial light on urban bats and might eventually affect the resilience of urban bat populations. Synthesis and applications. At light-emitting diodes (LEDs), the competitive advantage – the exclusive ability to forage on insect aggregations at lights – is reduced for light-tolerant bats. Thus, the global spread of LED street lamps might lead to a more natural level of competition between light-tolerant and light-averse bats. This effect could be reinforced if the potential advantages of LEDs over conventional illuminants are applied in practice: choice of spectra with relatively little energy in the short wavelength range; reduced spillover by precisely directing light; dimming during low human activity times; and control by motion sensors. Yet, the potential benefits of LEDs could be negated if low costs foster an overall increase in artificial lighting.
