“…[ 241,443 ] The most employed acidic molecules are those made of carboxylic acids, phosphoric acids, sulfonic acids, or boronic acids. [ 444 ] Otherwise, main basic molecules are those containing in their skeleton N‐rich groups with nonbonding electron pairs, such as amines, [ 445 ] pyridines, [ 446 ] imidazoles, [ 447 ] piperazines, [ 448 ] hydrazones, [ 449 ] pyrrolidines, [ 450 ] and morpholines. [ 451 ] In addition, molecules containing more than one pH‐responsive group (e.g., amino acids like tryptophan, aniline, etc.)…”

The ability of electronic devices to act as switches makes digital information processing possible. Succeeding graphene, emerging Inorganic 2D Materials (i2DMs) have been identified as alternative 2D Materials to harbor a variety of active molecular components to move the current silicon‐based semiconductor technology forward to a post‐Moore era based on molecule‐based information processing components. In this regard, i2DMs benefits not only for their prominent physiochemical properties (e.g., the existence of band gap, contrary to graphene), but also their high surface‐to‐volume ratio rich in reactive sites (functionalization capability). Nonetheless, since this field is still in an early stage, having knowledge of both i) the different strategies for molecularly functionalizing the current library of i2DMs, and ii) the different types of active molecular components is a sine qua non condition for a rational design of stimuli‐responsive i2DMs capable of performing logical binary operations at the molecular level. Consequently, this Review provides a comprehensive tutorial for covalently anchoring ad hoc molecular components —as active units triggered by different external inputs— onto pivotal i2DMs to assess their role in the expanding field of Molecule‐Programmable Nanoelectronics for electrically monitoring bistable molecular switches. Limitations, challenges, and future perspectives of this emerging field which crosses materials chemistry with computation are critically discussed.This article is protected by copyright.

“…From that time onward, a wide variety of pH papers have been proposed and mass-produced to test the acidity of aqueous solutions, and this cheap, simple, and quick method has become a must-have in laboratory equipment, especially for those applications in which pH measurements by glass electrode are unsatisfactory [ 1 , 3 , 4 , 5 ]. Another interesting application for pH papers can be found in the detection of acidic or alkaline volatile compounds in aerosol, but the details of this application are not discussed in this paper [ 6 , 7 , 8 , 9 ].…”

A novel 3 × 4 colorimetric sensing platform, named the chemometric-assisted litmus test (CLT), has been developed by covalently anchoring commercial pH indicators to ethylene vinyl alcohol (EVOH). The proposed device can be exploited for pH determinations in a wide range from 1 to 13 and in specific narrow ranges, achieving sufficient accuracy and errors below 0.5 pH units. The experimental procedure is simple, quick and reliable; equilibration is reached in less than 2 h, CLT pictures are acquired by a camera, and data treatment is performed applying chemometric techniques such as principal component analysis (PCA) and partial least square regression (PLS) to RGB indices.
