“…Time-resolved ps studies under 371 and 515 nm excitation revealed comparable mu tiexponential photobehavior, with lifetimes of 160-180 ps, 710-720 ps, and 2.3-2.5 n Modification of the arms of CBPHAT-1a with 1,2-diphenylethyne and 4,7-diphenylbenzo-2,1,3-thiadiazole resulted in the formation of more expanded HOFs (TolHAT-1 and ThiaHAT-1) [111]. Particularly, ThiaHAT-1 (Figure 6) showed a great stability up to 305 • C and a high BET surface area of 1394 m 2 g −1 , with a pore diameter of 15.5 Å.…”

“…Remarkably, the CBPHAT-1a/HCl interactio (adsorption, desorption) was reversible even at ambient temperature. Modification of the arms of CBPHAT-1a with 1,2-diphenylethyne and 4,7-diph nylbenzo-2,1,3-thiadiazole resulted in the formation of more expanded HOFs (TolHAT and ThiaHAT-1) [111]. Particularly, ThiaHAT-1 (Figure 6) showed a great stability up t 305 °C and a high BET surface area of 1394 m 2 g −1 , with a pore diameter of 15.5 Å. Th photophysical properties of Tol-HAT-1 and ThiaHAT-1 were elucidated by steady-sta and time-resolved spectroscopy, as well as single-crystal fluorescence microscopy.…”

Hydrogen-bonded organic frameworks (HOFs) have attracted renewed attention as another type of promising candidates for functional porous materials. In most cases of HOF preparation, the applied molecular design principle is based on molecules with rigid π-conjugated skeleton together with more than three H-bonding groups to achieve 2D- or 3D-networked structures. However, the design principle does not always work, but results in formation of unexpected structures, where subtle structural factors of which we are not aware dictate the entire structure of HOFs. In this contribution, we assess recent advances in HOFs, focusing on those composed of hexatopic building block molecules, which can provide robust frameworks with a wide range of topologies and properties. The HOFs described in this work are classified into three types, depending on their H-bonded structural motifs. Here in, we focus on: (1) the chemical aspects that govern their unique fundamental chemistry and structures; and (2) their photophysics at the ensemble and single-crystal levels. The work addresses and discusses how these aspects affect and orient their photonic applicability. We trust that this contribution will provide a deep awareness and will help scientists to build up a systematic series of porous materials with the aim to control both their structural and photodynamical assets.

“…There are several advantages associated with various isostructural hexagonal networks (HexNets) of C3-symmetric carboxylic acids with p-conjugated cores. A key factor is the mosaic of materials has been formed using 1,2-diphenylethyne (tolane) and 4,7-diphenylbenzo-2,1,3-thiadiazole, which defines the relationship of carboxy-phenyl and -biphenyl arms [ 117 ].…”

Photosensitive supramolecular systems have garnered attention due to their potential to catalyze highly specific tasks through structural changes triggered by a light stimulus. The tunability of their chemical structure and charge transfer properties provides opportunities for designing and developing smart materials for multidisciplinary applications. This review focuses on the approaches reported in the literature for tailoring properties of the photosensitive supramolecular systems, including MOFs, MOPs, and HOFs. We discuss relevant aspects regarding their chemical structure, action mechanisms, design principles, applications, and future perspectives.

“…Therefore, supramolecular complexes self-assembled through intermolecular hydrogen-bonding interactions, named HOFs, have been proven to be a potentially tunable platform for constructing functional materials [4][5][6][7]. So far, various supramolecular HOFs, made by employing organic molecules, have been reported and employed in fields like sensing, capture, separation, proton conductivity, catalysis, and so on [8][9][10][11][12][13][14].…”

Here, we report a design strategy for constructing supramolecular organic frameworks by introducing 1H-pyrazole groups to aromatic cores as non-coplanar molecules to form diverse supramolecular assemblies through multiple 1H-pyrazole [N−H···N] hydrogen bonds as well as other weak interactions. The new supramolecular organic frameworks displayed interesting crystallization-induced emission (CIE) behavior.
