“…This response can be expressed in the form of nonlinear behavior of excitons in MOF or thermally induced volume expansion, affecting the MOF optical transmittance. These effects make it possible to implement both ultra-fast (150 fs) optical information processing [42] and relatively fast processes of data transmission and encryption [43][44][45][46]. However, extremely high energies of exciting laser pulses can lead to irreversible interaction of MOFs with light: Observation of the cold and hot laser ablation of MOFs, as a result of which nanometer scale derivatives can be formed, demonstrating NLO properties already at the nanoscale [47][48][49].…”

Unique structural features of metal-organic frameworks such as their organic-inorganic nature, coupled with a series of weak and strong chemical interactions, provide these hierarchical materials with an adaptive response to external stimuli (including light). The latter allows one to demonstrate energy-efficient and ultra-fast optical processes for light generation, conversion, triggering, encryption, absorption, and transition. Covering the current state and perspectives in this new field of material science for photonics, the report aims to develop a deep understanding of the interaction of light with such hierarchical materials to create sustainable and energy efficient optical devices.

“…Concerning the combination of flexibility and the ligand length, we have considered specific one- and two-dimensional MOFs from our previous works. , For such MOFs, we have detected thermally induced volume expansion, and according to the k -NN model, they can be found in green and yellow regions corresponding to the high probability of PT under the influence of the temperature/pressure and guest molecules, respectively (Figure S6 of the Supporting Information). Also, we have examined an elastic MOF with a densely catenated backbone, showing simultaneously the PT under the influence of guest molecules and temperature.…”

Metal−organic frameworks (MOFs) possess a virtually unlimited number of potential structures. Although the latter enables an efficient route to control the structurerelated functional properties of MOFs, it still complicates the prediction and searching for an optimal structure for specific application. Next to prediction of the MOFs for gas sorption/ separation and catalysis via machine learning (ML), we report on ML to find MOFs demonstrating a phase transition (PT). On the basis of an available QMOF database (7463 frameworks), we create and train the autoencoder followed by training the classifier of MOFs from a unique database with experimentally confirmed PT. This makes it possible to identify MOFs with a high potential for PT and evaluate the most likely stimulus for it (guest molecules or temperature/pressure). The formed list of available MOFs for PT allows us to discuss their structural features and opens an opportunity to search for phase change MOFs for diverse physical/chemical application.
