Phase-change semiconductor is one of the best candidates for designing nonvolatile memory, but it has never been realized in organic semiconductors until now. Here, a phase-changeable and high-mobility (3,6-DATT) first synthesized. Benefiting from introduction electrostatic hydrogen bond (S···H), molecular conformation 3,6-DATT crystals can be reversibly modulated by electric field ultraviolet irradiation. Through experimental theoretical verification, tiny difference leads to crystalline polymorphisms dramatically distinct charge transport properties, based on which high-performance phase-change memory transistor (OPCMT) constructed. The OPCMT exhibits quick programming/erasing rate (about 3 s), long retention time (more than 2 h), large window (i.e., threshold voltage shift over 30 V). This work presents new molecule design concept with reversible transition opens novel avenue devices other functional applications.

The upregulation of 4-hydroxyphenylpyruvate dioxygenase (HPPD) can protect plants from adverse abiotic stress. Therefore, studying the changes HPPD under stress is extremely valuable. In this study, we employed a rational molecular design strategy to prepare an HPPD-responsive fluorescent probe consisting pyrene fluorophore, linker and benquitrione skeleton recognition moiety that functions via aggregation–disaggregation sensing mechanism. As predicted, exhibited obvious turn-on fluorescence response towards HPPD. addition, in vivo imaging demonstrated excellent capability track Arabidopsis thaliana, dynamic were monitored different degrees high temperature Cadmium (II) ion (Cd2+) This work provides efficient for acquiring noninvasive probe, which could evaluate degree be further exploring resistance mechanism plants.

Following the progress on mono-heteroaryl azo switches (Het-N=N-Ph), a few bis-heteroaryl (Het-N=N-Het) have been studied recently, whereas nonsymmetric ones (Het1 -N=N-Het2 ) that can combine respective merits of each heterocycle, received little attention. Here we report thiazolylazopyrazoles as visible-light switching character thiazole ring and ease o-substitution pyrazole ring. Thiazolylazopyrazoles achieve (near-)quantitative isomerization in both directions long Z-isomer thermal half-lives several days. In contrast to drastically destabilizing effect o-methylation, o-carbonylation remarkably stabilize Z isomers by inducing attractive intramolecular interactions (dispersion, C-H⋅⋅⋅N bond, lone-pair⋅⋅⋅π interaction). Our work highlights importance rational combination two heterocycles suitable structural substitution developing switches.
