Lead-carboxylate/polyiodide hybrids constructed from halogen bonding and asymmetric viologen: structures, visible-light-driven photocatalytic properties and enhanced photocurrent responses

Abstract

Two lead-carboxylate/polyiodide hybrids constructed from halogen bonding and asymmetric viologen have been synthesized, which exhibit efficient photocatalytic degeneration performances.

Quaternary Phosphorus‐Induced Iodocuprate(I)‐Based Hybrids: Water Stabilities, Tunable Luminescence and Photocurrent Responses

“…Photocurrent generation has been observed in metal halide based hybrids , . Photoelectrochemical experiments have also been performed on 1 , 3 and 4 according to typical method.…”

Crystal engineering of coordination-polymer-based iodine adsorbents using a π-electron-rich polycarboxylate aryl ether ligand

“…Thus, CPs have attracted increasing attention in the recent years. [25][26][27][28][29][30][31] It was found that the adsorption of I 2 by crystalline porous materials, including CPs, was based on noncovalent interactions like halogen bonding interactions between I 2 and Lewis basic sites [32][33][34][35] or charge-transfer interactions between the electron-poor I 2 and π-electron rich aromatics. [36][37][38][39][40][41] Thus, a combination of halogen bond and CT interactions between the guest I 2 molecules and the host frameworks imparts a comprehensive tuning effect on the iodine capture process.…”

Core‐Shell Structured Layered Lanthanide‐Organic Complexes with Stilbazolium‐type Dye Encapsulation for Multifunctional Performances

“…But after loading with (DEAST)I, their currents decrease greatly (0.72×10 −7 A for (DEAST)I@La‐LMOC, 0.63×10 −7 A for (DEAST)I@Nd‐LMOC). According to universal accepted photocurrent generation mechanism, radicals on organic moiety can generate under irradiation, then the electrons on organic moiety move to ITO substrates to produce the recyclable currents . In this work, for Ln‐LMOC, radicals can appear on BTB to produce BTB .…”

“…According to universal accepted photocurrent generation mechanism,r adicals on organic moiety can generate under irradiation, then the electrons on organic moiety move to ITO substrates to produce the recyclable currents. [34] In this work, for Ln-LMOC,r adicals can appear on BTB to produce BTBC radicals, and electron-rich Ln 2 O 16 dimers can transfer their electrons to BTBC radicals. Because there are covalently bonded between the radicalc enters and electron-rich Ln 2 O 16 units, this electront ransfer is smooth.…”
