Mechanofluorochromic behaviors of β-iminoenolate boron complexes functionalized with carbazole

Abstract

New β-iminoenolate boron complexes exhibit different mechanofluorochromic properties due to the excimer and monomer transformation.

Bifunctionalized conjugated microporous polymers for carbon dioxide capture

“…S10 and S11). Both of the bifunctionalized polymer networks showed very similar adsorption selectivities of 4.0 for CO 2 /CH 4 and 30 for CO 2 /N 2 at 273 K. The CO 2 / N 2 adsorption selectivity by both of the polymer networks is comparable to that of some other MOPs under the similar conditions, such as the triazine-functionalized CMPs (9.0e25.2 at 298 K) [50], the amide-functionalized CMPs (8.5e12 at 298 K) [26], the imine-linked porous polymer frameworks (14.5e20.4 at 273 K) [52], the carbazolic porous organic frameworks (19À37 at 273 K) [58], and the nanoporous azo-linked polymers (30e43 at 273 K) [34], though it is lower than that of some other reported MOPs with the CO 2 /N 2 adsorption selectivity higher than 100, such as the azobridged covalent organic polymer of Azo-COP-2 with a CO 2 /N 2 adsorption selectivity of 109 at 273 K [59], the porous benzimidazole-linked polymer of BILP-2 with a CO 2 /N 2 adsorption selectivity of 113 at 273 K [48], the PPN-6-SO 3 NH 4 with a CO 2 /N 2 adsorption selectivity of 196 at 295 K, and the tri(4-ethynylphenyl) amine-based porous aromatic framework with amine groups of PAF-33eNH 2 with the CO 2 /N 2 adsorption selectivity as high as 250 at 273 K [29]. However, the absolute amount of CO 2 adsorbed was only 1.19 mmol g À1 for PAF-33eNH 2 at 273 K/1.0 bar [29], much lower than that of the BFCMP-2 (2.77 mmol g À1 at 273 K/1.13 bar) in this work.…”

Synthesis, photoluminescence and Judd–Ofelt analysis of red LiGd5P2O13 : Eu3+ phosphors for white LEDs

“…5,6 It is well-known that phosphates possess many excellent properties as phosphor hosts, i.e. Recently, many novel Eu 3+ -doped compounds have been reported as promising candidates as potential red-emitting phosphors for LED application.…”

Recent progress of optical functional nanomaterials based on organoboron complexes with β-diketonate, ketoiminate and diiminate

“…[39][40][41][42] By grinding powder samples in the crystal state, materials typically convert into the amorphous state; the resulting molecular distribution would thus be randomized, and the degree of intermolecular interactions should be significantly different. As a result, changes in emission color or intensity can thus be observed.…”
