TL;DR: In this article, photochromic metal organic frameworks (MOFs) containing photo-chromic 1,4,5,8-naphthalenediimide (NDI) core and metal ions selected from Mg, Ca or Sr.
Abstract: The present invention disclose photochromic metal organic frameworks (MOFs) containing photochromic 1,4,5,8-naphthalenediimide (NDI) core and metal ions selected from Mg, Ca or Sr. The developed MOFs find application in inkless and erasable printing wherein they retain the photogenerated colour for a prolonged period of time so that the 10 printed content remains legible/readable for reasonable time.

TL;DR: In this paper, the authors provide an overview of the best practices for C-H activation as well as key advances in asymmetric, photoinduced and electrocatalytic-mediated catalysis for this synthetic platform.
Abstract: Transition metal-catalysed C–H activation has emerged as an increasingly powerful platform for molecular syntheses, enabling applications to natural product syntheses, late-stage modification, pharmaceutical industries and material sciences, among others. This Primer summarizes representative best practices for the experimental set-up and data deposition for C–H activation, as well as discussing key developments including recent advances in asymmetric, photoinduced and electrocatalytic C–H activation. Likewise, strategies for applications of C–H activation towards the assembly of structurally complex (bio)polymers and drugs in academia and industry are discussed. In addition, current limitations in C–H activation and possible approaches for overcoming these shortcomings are reviewed. This Primer provides an overview of the best practices for C–H activation as well as key advances in asymmetric, photoinduced and electrocatalytic-mediated catalysis for this synthetic platform. An overview of how C–H activation facilitates the synthesis of molecules such as structurally complex (bio)polymers and drugs is provided along with the current challenges and priorities for the next decade.

TL;DR: In this paper, a new procedure for the synthesis of titanium silicate-1 (TS-1) with high Ti (Si + Ti) ratios is reported, and the rationale for the method adopted and the reasons for the incorporation of more Ti (than reported by earlier workers) are discussed based on liquid-phase n.m.t.r.

TL;DR: The experimental results explicitly elucidate that more hydrophobic imidazolium and phosphonium cations carrying longer alkyl chains of ILs were weak stabilizers for CT, while smallAlkyl chain molecules of triethyl ammonium salts are strong stabilizers and therefore more biocompatible for CT stability.
Abstract: In view the of wide scope of structural information of biomolecules in biocompatible ionic liquids (ILs) in various applications including chemical and biochemical, it is essential to study the productive preferential interactions between biological macromolecules and biocompatible ILs. We have therefore explored the stability and activity of α-chymotrypsin (CT) in the presence of five ILs from different families, such as triethyl ammonium acetate (TEAA), triethyl ammonium phosphate (TEAP) from ammonium salts, 1-benzyl-3-methylimidazolium chloride ([Bzmim][Cl]), 1-benzyl-3-methylimidazolium tetrafluoroborate ([Bzmim][BF4]) from imidazolium salts and tetra-butyl phosphonium bromide (TBPBr) from phosphonium families. Circular dichroism (CD) and UV–vis spectrophotometer experiments were used to study CT stabilization by ILs, related to the associated structural changes and enzyme activity studies, respectively. We observed that all ILs have a dominant contribution to the stabilization of CT. The stability and activity of CT depends on the structural arrangement of the ions of ILs. Our experimental results explicitly elucidate that more hydrophobic imidazolium and phosphonium cations carrying longer alkyl chains of ILs ([Bzmim][Cl], [Bzmim][BF4] and TBPBr) were weak stabilizers for CT, while small alkyl chain molecules of triethyl ammonium salts (TEAA and TEAP) are strong stabilizers and therefore more biocompatible for CT stability. Our CD and NMR measurements reveal that TEAA is a refolding additive for CT from a quenched thermal unfolded enzyme structure.
