“…The observed nitrogen content of PCTP-1 networks was almost double the PCTP-2 networks, and the relatively high Q st value in PCTP-1 is in line with their CO 2 adsorption capacity. Here, the CO 2 gas uptakes and Q st are dependent on the material surface area, pore size and the number active nitrogen species in the pore walls of the networks [52]. Q st values of PCTP-1 and PCTP-2 were relatively lower than those of porous framework materials [51,[53][54] where P is the pressure, T is the temperature, θ is the amount adsorbed, and R is the universal gas constant.…”

A novel metal-doping strategy was developed for the construction of iron-decorated microporous aromatic polymers with high small-gas-uptake capacities. Cost-effective ferrocene-functionalized microporous aromatic polymers (FMAPs) were constructed by a one-step Friedel-Crafts reaction of ferrocene and s-triazine monomers. The introduction of ferrocene endows the microporous polymers with a regular and homogenous dispersion of iron, which avoids the slow reunion that is usually encountered in previously reported metal-doping procedures, permitting a strong interaction between the porous solid and guest gases. Compared to ferrocene-free analogues, FMAP-1, which has a moderate BET surface area, shows good gas-adsorption capabilities for H2 (1.75 wt % at 77 K/1.0 bar), CH4 (5.5 wt % at 298 K/25.0 bar), and CO2 (16.9 wt % at 273 K/1.0 bar), as well as a remarkably high ideal adsorbed solution theory CO2 /N2 selectivity (107 v/v at 273 K/(0-1.0) bar), and high isosteric heats of adsorption of H2 (16.9 kJ mol(-1) ) and CO2 (41.6 kJ mol(-1) ).

The development of advanced nonlinear media as well as active optical materials for light conversion applications is an ongoing process. [1,2] Aims include improved conversion efficiencies, brilliance, i.e., beam quality, and accessible target wavelengths. Light-converting materials for white-light generation are of particular interest, e.g., for white light-emitting diodes (LEDs) and their applications. Here, phosphors offer great efficiency even at low driving power densities and huge spectral versatility across the visible spectrum. [3][4][5][6] The virtually perfect Lambertian angular emission pattern of such functionalized LEDs is highly desirable in applications such as backlights in displays, while others require low-étendue sources with limited angular spread. [7,8] Laser-driven phosphors in automotive headlights are a recent, prominent example where a small laser spot is exploited to achieve a virtual point source and tailorThe vast optical nonlinearity of 1,3,5,7-tetraphenyladamantane (AdPh 4 ) enables efficient frequency conversion. The observed spectrum depends heavily on the material's habitus. In particular, it shows nonlinear white-light generation when its powder form is irradiated in the near-infrared, similar to an analogous organotin sulfide cluster [(PhSn) 4 S 6 ]. In contrast, single crystals of AdPh 4 exclusively exhibit narrow-band second-harmonic generation, i.e., discrete conversion within the crystal, rather than spectrally broadband white-light emission. This shows that crystallinity restricts the nonlinear response to the symmetryallowed higher-harmonics, in this case the even-numbered, second harmonic, and inhibits the quasi-continuum white-light emission. Using the diamondoidbased material significantly enhances compatibility with conventional production techniques using photorefractive polymers and is thus an important step towards the fabrication of all-integrated white-light emitting devices.
