Regulation and application of organic luminescence from low-dimensional organic–inorganic hybrid metal halides

Abstract

Organic solid-state luminescence shows broad application prospects in fields such as sensing, luminescent devices, information storage, and biological imaging. However, most organic molecules show poor luminescence performance in aggregated states....

Passivation of Organic–Inorganic Hybrid Perovskite with Poly(lactic Acid) to Achieve Stable Red-Light Flexible Films

“…The diversity of organic cations and inorganic polyhedra endows low-dimensional OIHPs with structural tunability and various unique photophysical properties. − For example, Li et al improved the yellow-light quantum yield (QY) of zero dimension (0D) Sb-based perovskite from 0 to 79.57% by changing the spatial conjugation degree of organic molecules . Kang et al realized the adjustment of the optical band gap of organic–inorganic hybrid perovskite from 2.75 to 2.88 eV by changing the planar π-conjugated organic cation size .…”

Broadband Green Luminescence and Phase Transition in Low-Dimensional Organic–Inorganic Hybrid Iodate

“…23−25 And among them, organic cations play a key role in the process of light harvest. 26,27 Herein, 9-aminoacridine attracted our attention due to its large ring-conjugated system and rigid planar structure as well as its wide application in biology and optoelectronics. Moreover, in the presence of inorganic acids, 9-aminoacridine molecules tend to be protonated, which is beneficial to generate strong hydrogen bonding interactions between the host−guest components and further generate a stable crystal structure.…”

“…Different from metal iodate systems, organic–inorganic hybrid iodates are less reported, and only a few of them have been systematically studied such as (C 6 H 20 N 3 )­(IO 3 ) 3 ·2H 2 O, [C 5 H 6 NO­(IO 3 )] 2 and [ o -C 5 H 4 NHOH] 2 [I 7 O 18 (OH)]·3H 2 O. − However, due to its structural diversity and abundant intermolecular linkages, the introduction of organic molecules makes this system an intriguing treasure to be explored. Generally, organic–inorganic hybrid systems can form highly ordered chromophores and uniformly oriented transition dipole moments, which are ideal host–guest systems for constructing micron-scale optical devices. − Especially those with low-dimensional structures could exhibit strong quantum-limited and highly localized charges, capable of generating high exciton energies and stable excitation emission. − And among them, organic cations play a key role in the process of light harvest. , Herein, 9-aminoacridine attracted our attention due to its large ring-conjugated system and rigid planar structure as well as its wide application in biology and optoelectronics.

Tunable multicolor fluorescence of polyurethane derivatives controlled by molecular weight

“…8–13 However, such hybrid materials exhibit poor reproducibility, low stability, and complex manufacturing processes. 14–16 Inorganic materials, on the other hand, are constrained by high costs and toxicity. 17–19 Therefore, achieving controlled multicolor fluorescence regulation by simple and efficient strategies remains elusive.…”
