Quadruple Photoresponsive Functionality in a Crystalline Hybrid Material: Photochromism, Photomodulated Fluorescence, Magnetism and Nonlinear Optical Properties

“…Recent studies have demonstrated that the hybrid PMs, [13] particular crystalline hybrid PMs (CHPMs), [14] hold promise as inheriting the merits of each constituents. Hitherto, most of CHPMs are supported by photodeformable ligands with examples of diarylethylene‐/azo‐derivatives [15–18] or photoresponsive ligands like pyridinium‐derivatives [19–30] . Besides the CHPMs based on photodeformable or photoresponsive ligands, [15–40] the conjugated N ‐heterocycle moieties as potential electron acceptors (EAs) are also desirable units for yielding CHPMs [41–50] .…”

“…Hitherto, most of CHPMs are supported by photodeformable ligands with examples of diarylethylene-/azo-derivatives [15][16][17][18] or photoresponsive ligands like pyridinium-derivatives. [19][20][21][22][23][24][25][26][27][28][29][30] Besides the CHPMs based on photodeformable or photoresponsive ligands, the conjugated N-heterocycle moieties as potential electron acceptors (EAs) are also desirable units for yielding CHPMs. [41][42][43][44][45][46][47][48][49][50] The assembly of various EAs moieties, electron donors (EDs) species, and metal ions generates assorted CHPMs driven by photoinduced electron-transfer (ET) between EDs and EAs, [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55] and the resulting CHPMs feature additional fascinating photoresponsive functionality like photomagnetism, photocurrent, sensor for X-ray, etc.…”

Donor–Acceptor‐Type Organic‐Small‐Molecule‐Based Solar‐Energy‐Absorbing Material for Highly Efficient Water Evaporation and Thermoelectric Power Generation

“…Currently the common photothermal materials mainly involve carbon-based inorganic materials, [18][19][20] metal-based inorganic materials, [21,22] organic-polymer, [23][24][25] organic-inorganic hybrid materials, [26,27] organic cocrystals materials, [28] and purely organic-small-molecule materials. [29] Among them, photo thermal materials comprised of organic-small-molecules have attracted growing attention due to their unique advantages in processing feasibility, structural diversity and fine-tuned properties.…”

1-(2-Methylphenyl)-4,4′-bipyridin-1-ium tetrafluoridoborate

“…This is longer than the C-N bond lengths observed in N-aryl structures of monosubstituted 4,4 0 -bipyridinium in: N-phenyl [1.460 (2) A ˚; Coe et al, 1998], N-naphthyl [1.455 (2) A ˚; Lin & Zhao, 2015], or N-biphenyl [1.449 (5) A ˚; Schoder et al, 2019]. The adjacent methyl group of the tolyl group is a likely factor for this longer C-N bond length, which is corroborated by the longer C-N bond distances of 1.463 (9) and 1.482 (9) A ˚resulting from an orthomethyl group in the structure of the disubstituted N,N 0 -bis(3methyl-4-carboxylatophenyl)-4,4 0 -bipyridinium bridging ligand (Wang et al, 2020).…”
